ATTORNEYS United States Patent f 3,452,740 SPRING GUIDE MANIPULATOR Wolf F. Muller, New York, N .Y., assignor to United States Catheter & Instrument Corporation, Glens Falls, N.Y., a corporation of Delaware Filed May 31, 1966, Ser. No. 553,850 Int. Cl. A6111 00, 17/00; A61m 25/ 00 U.S. Cl. 128-2 10 Claims ABSTRACT 0F THE DISCLOSURE This invention is directed to a handle for attachment to, and manipulation of, spring guides that are used primarily as internal vascular probes to guide catheters to specific locations within the circulatory system. This handle remains in the hands of the doctor or surgeon outside of the patients body but permits manipulation of the spring guide and catheter within the patients body. The handle includes a pair of chucks for securely holding at the proximal ends both the spring guide coils and the spring guide tension wire with a linkage therebetween.
This invention relates to new and useful improvements in manipulative handles in general and particularly seeks to provide a novel handle for the manipulation of spring guides used primarily in internal vascular probes.
The marked advances in cardiac and vascular surgery in the past few years and other medical problems that require diagnostic study of the vascular beds and systems has led to the extensive use of cardiac or vascular catheters, particularly for retrograde aortography and angiocardiography, and less often to take blood samples, determine oxygen content, infuse medicaments, etc. at internal sites and various other uses that require the insertion of a relatively long catheter to an internal site that requires movement of the catheter into branch vessels at sharp angles relative to the feeding direction of the catheter.
The most common method for insertion of such catheters is the percutaneous technique described in 1953 by Sven Ivar Seldinger. In this procedure a local anesthesia is administered and a skin puncture made at a small angle to the vessel (eg. femoral in the leg or brachial in the arm) with an obturator positioned within a cannula. Once the unit has been properly located in the vessel, the obturator is removed and the exible spring guide then inserted through the cannula into the vessel for a short distance. Pressure is then applied to hold the spring guide in place while the cannula is withdrawn. The spring guide is then fed into the vessel generally under the fluoroscope until the desired point is reached which may or may not require considerable manipulation if there are branched vessels or curves concerned. Thereafter the catheter is passed over the flexible spring guide and fed into the desired position and the spring guide then withdrawn from the catheter unless both are needed for cooperative manipulation purposes.
A particularly useful spring guide for these purposes is disclosed and claimed in my co-pending application for U.S. Letters Patent Ser. No. 512,143, filed Dec. 7, 1965, now abandoned in favor of Ser. No. 563,927, filed June 29, 1966. In that form of spring guide its distal end may be straightened or curved by manipulation of an inner tension wire from its proximal end outside the patient and it may also be curved after a catheter is placed thereover to cause the catheter to curve.
'Ihe handle of this invention is particularly useful for manipulating spring guides of the abovementioned type.
Therefore, an object of this invention is to provide a manipulative handle attachable to the proximal end of a 3,452,740 Patented July l, 1969 spring guide containing an inner tensioning wire and having devices for controllably applying tension to or releasing tension from the inner wire.
Another object of this invetnion is to provide a handle of the character stated in which the tensioning devices may be locked in their tension-applying position to maintain the distal end of the attached spring guide in its curved condition.
Another object of this invention is to provide a handle of the character stated which includes means for rotating the attached spring guide and its contained tensioning wire relative to the handle.
Another object of this invetnion is to proivde a handle of the character stated that includes a two-valve manifold to permit the injection of liquids into a connected catheter while the spring guide is retained therein.
A further object of this invention is to provide a handle of the character stated that can be effectively used to progressively advance a catheter after it has been threaded over the spring guide.
A further object of this invetnion is to provide a handle of the character stated which is expressly designed for one-hand use.
A further object of this invention is to probide a handle of the character stated which is simple in design, rugged in construction and economical to manufacture.
With these and other objects which will be more apparent, the invention will be more fully understood by reference to the drawings, the accompanying detailed description and the appended claims.

Referring to the drawings in detail, the invention as illustrated is embodied in a manipulative handle including a cylindrical body portion generally indicated A, a front chuck generally indicated B for securely holding the proximal end coils of a spring guide, a back chuck generally indicated C for securely holding the proximal end of the spring guide tension wire and being axially movable with respect to the front chuck, a wheel generally indicated D for rotating both chucks relative to the body portion, A and a linkage assembly generally indicated E for effecting axial movement of the back chuck C toward or away from the front chuck B.
The body portion A includes a front end closure flange 5 rigidly connected to an axially spaced mounting block 6 by a spacer rod 7.
The mounting block 6 is preferably fabricated from a single piece of rod stock and machined to define a forwardly projecting vertical rib 8 and a pair of longitudinally extending horizontal slideways `9, 9, the bases of which are coplanar with the lateral faces of the rib 8. The rear of the mounting block is provided with a relatively deep large diameter bore 10 and a smaller diameter bore 11 which connects with a still smaller bore (not shown) extending through the rib 8 for the passage of a torque tube as will be hereinafter more ful-ly described.
A slide piece generally indicated 12 is mounted for reciprocatory movement in block 6 and includes a hollow cylindrical stem 13 which ts into the bore 11 and a disk end 14 which tits into the bore 10. A pair of oppositely disposed stub axles 15, 15 which are secured to the stem 13 and extend into the slideways 9, 9 are provided at their outer ends with rollers 16 engaged in the slideways 9.
A longitudinally extending tubular stud 17 is secured to the body rib 8 and carries a coil compression spring 18. A bifurcated spring yoke 19 is itted over the end of the stud 17 and has its arm pivotally attached to the axles 15, thus maintaining the spring 18 under compression and constantly urging slide 12 toward the right as viewed in FIGS. 2 and 3 of the drawings.
The slide 12 and its associated elements is adapted to be reciprocated by the linkage assembly E which includes a pair of spaced parallel downwardly extending levers 20, 20 pivotally connected at one end to the axles 15 and at their other end to a spacer pivot 21. A lever plate 22, provided with a nger ring 23, has one pivotally connected to the spacer pivot 21 and its other end pivotally connected within a radial slot as at 24 in the closure ilange 5. The levers 20 and 22 thus form a toggle which can be moved into its open position by moving the nger ring 23 toward the body of the handle and thus moving the slide 12 to the left against the pressure of the coil spring 18. Release of the nger ring permits the spring 18 to force the slide 12 to the right and to move the toggle levers back to their initial positions.
The lever plate 22 is provided with a slot 25 generally parallel with its upper edge which receives the pin 26 of a vertical locking bar 27 slidably mounted on the spacer rod 7. Its normal position is indicated in full lines in FIG. 2 of the drawings and can be moved to the left as shown in FIG. l when the toggle dened by the levers 20 and 22 is in its open position to hold it in that position and maintain the slide 12 at its left end limit of movement.
A swivel generally indicated 28 includes a hollow stem 29 rotatably carried within the stem 13 of the slide 12 and a relatively thick disk end 30 which ts into the bore 10. A thrust washer 31, formed from nylon or other suitable material, is secured within an annular recess formed in the outer face of the slide disk 14 and serves as a slide seat for the disk 30 of the swivel 28. The end of the swivel stem 29 extends slightly beyond the end of the slide stem 13 and is provided with an annular retaining groove 32 engageable with the pin end of a retaining screw (not shown) which extends radially through the mounting block 6. Thus rotation of the swivel is permitted while axial movement thereof is prevented.
A rotatable torque tube 33 is aflxed at one end to the cylindrical body portion of a pin vise generally indicated `34 rotatably mounted in the closure flange 5 and restrained from axial movement with respect thereto by a pin screw 35 extending radially therethrough and having its pin end engaged within an annular groove formed adjacent the end of the vise body portion. Incidentially, the pin screw 35 also secures the handle cover or shell in place as may be seen in FIG. 2.
The torque tube 33 extends axially from the closure ilange 5 through the locking bar 27, the tubular stud 17,
4 the rib 8 of the mounting block 6 and the stem and disk of the swivel 28 to a position somewhat beyond the swivel. One side of the torque tube 33 is notched as at 36 for connection with the front chuck B.
A radially offset, longitudinally extending, internally threaded tension post 37 is secured to the disk 30 of the swivel 28 and has a length approximately equal to that of the projecting end of the torque tube 33. A slide rod or stud 38, having a length substantially greater than that of tension post 37, is also secured to the disk 30 in spaced parallel relation to the tension post.
The front chuck B includes a body 39 containing a cam-actuated clamp (not shown), a knurled clamp-actuating sleeve 40 and a spring-biased pin 41 for locking the chuck onto the projecting end of the torque tube 33. The chuck B is provided with an axial duct passing through the internal clamp for receiving and retaining the proximal end of the spring guide coil while permitting the tensioning wire thereof to project therethrough for engagement by the back chuck C and for permitting the chuck to be attached to the end of the torque tube. When the front chuck B is attached to the torque tube the tension post 37 and slide stud 38 pass freely through longitudinal passages suitably provided therein so that relative sliding motion can take place between the chuck and the tension post and slide stud and permit relative axial motion to take place between the chuck and the swivel 28.
The back chuck C includes a body 42 containing a camactuated detent (not shown), a knurled detent-actuting sleeve 43 and knobbed tension screw 44. The chuck C is provided with an axial duct passing through the internal detent for receiving and retaining the proximal end of the spring guide tensioning wire. The back chuck C is slidably mounted on the stud 38 and is connected to the swivel 28 by engagement between the tension screw 44 and the tension post 37. The tension screw 44 is freely rotatable with respect to the back chuck C but is restrained against axial movement by suitable means shown in dotted lines) so that the tension screw is not only used to connect the back chuck with the swivel but may also ybe used to vary the spacing therebetween and thus correspondingly vary the total tension to be applied to the tensioning wire of the attached spring guide.
The torque tube 33 may be rotated in either direction relative to the handle body A by the knurled wheel D which is pin connected to the cylindrical body of the pin vise 34. Since the front chuck B is rmly attached to the torque tube any rotation thereof will be transmitted through the chuck to the swivel 28 via the tension post 37 and stud 38 as well as to the attached back chuck C. Thus the torque tube, the two chucks and the swivel all rotate as a unit.
Axial movement ofthe slide 12 and its associated swivel 28 which results from manipulation of the linkage assembly E effects a corresponding axial movement of the rear chuck C and a relative movement of the rear chuck C with respect to the front chuck B. It is this relative movement between the chucks that applies and releases tension to and from the tensioning wire of the attached spring guide. FIG. 4 shows the relative positions of the chucks and swivel under normal or nontension conditions, While FIG. 5 shows their relative positions when tension has been applied. No axial motion of the front chuck B takes place because it is attached to the torque tube 33 that has no axial movement at any time, only rotary.
A telescoping tube 46 of square-section is carried within the torque tube 33 and projects beyond the end of the pin vise 34 for connection to a two-valve manifold as will be hereinafter more fully described.
A tubular shell or cover 47, suitably slotted to permit the linkage assembly E and the top of the locking bar 27 to project therebeyond, tits snugly over the mounting block 6 and closure flange 5 and is retained in position by the pin screw 35 as mentioned before.
A two-valve manifold (see FIGS. 911) generally indicated 48 is operably connected to the outer projecting end of the telescoping tube 46 and includes a transversely extending stainless steel body 49 provided at each end with a female Luer fitting 50. Each of the fittings 50 connects with a horizontal duct 51 which communicates 'with a vertical tappered bore 52 containing a rotatable plug valve 53 provided at its projecting upper end with an actuating handle 54 pivotally connected thereto. Each valve 53 is provided with a single tranverse duct 55 horizontally aligned with its associated duct 51 and with an inner horizontal duct 56 extending into communication with a relatively large diameter ibore 57 disposed in axial alignment with the telescoping tube 46.
A hollow rotary spindle generally indicated S8 fits snugly within the bore 57 and is provided at its forward end with a catheter connecting fittings 59. The spindle 58 is provided intermediate its ends with a pair of of fianges 60, 60 having an outer face spacing equal to the length of the bore 57. A second pair of flanges 61, 61, having conical interfaces 62, are symetrically positioned intermediate the flanges 60 so that the zone defined by their conical interfaces is aligned with the ducts 56. The conical face of the forward flange 61 is provided with four radial ducts 63 extending into communication with the axial bore of the spindle. A rubber O-n'ng 64 is fitted into each annulus defined by each pair of anges 60 and 61.
The inner end of the spindle 58 is provided with an externally threaded boss 64 and the male half 65 of a toothed coupling or clutch, the female half 66 of which is affixed to the end of the telescoping tube 46. An inter- :nally threaded locking cap 67 is carried by the tube 46 for the engagement with the boss 64 to secure the two halves of the coupling together.
A U-channel pressure cap 68 having front and rear upwardly extending iianges 69, y69 spans the bottom of the manifold body 49 and is of sufficient length that its center web presses against the bottoms of the tapered plug valves 53 to retain them in place while permitting their rotation. The cap 68 is secured by a knurled disk nut 70 threadably engaged with a stud 71 affixed to the maniiiold body 49 and projecting downwardly through a hole in the Web of the cap. The cap flanges 69 are just suiciently high to engage the lower edge portions of the outer faces of the flanges 60= and thus restrain the spindle 58 against axial movement while permitting its rotation.
Proper alignment of the valve ducts 55 with the ducts 51 and 56 when the plug valves are turned to the open positions is assured through the use of upwardly projecting stop pegs 72 against which the handles or levers 54 are adapted to abut.
If desired the manifold body 49 may be provided with a. vertical duct 73 extending into communication with the bore 57 for connection with external injection fitting 74 provided with a self-sealing rubber disk (shown in FIG. 9 in plan) for use when supplemental or flashing solutions are to be introduced by a hypodermic needle.
An externally threaded collar 75 (see FIG. 9) is aixed to the telescoping tube 46 adjacent to the coupling element 66 and carries an external sleeve 76 threadably engaged therewith. The sleeve 76 serves as an adjustable abutment engageable against the end of the pin vise 34 for accurately setting the initial or retracted position of a catheter connected to the fitting 59 with respect to the spring guide secured to the chucks B and C. In this way the distal ends of both the spring guide and catheter may be brought into exact registry prior to the time that the catheter is payed out or advanced relative to the spring guide during probing manipulations.
FIGS. 7 and 8 of the drawings show a preferred form of spring guide for use with the handle of this invention and formed from a continuous wire coil 77, the helices of which are individually tapered at the distal end to define a series of generally wedge-shaped spaces 78 therebetween.
The distal end of the spring guide is closed by a cap or plug 79 connected to one end of an internally extending tensioning wire 80, the other end of which projects beyond the proximal end of the spring guide and is provided with an enlarged pellet 81.
The proximal end of the spring guide is stiffened by an external stainless steel tube 82 rolled into tight contact therewith and provided with an annular groove 83 engageable by the clamp of the front chuck B to additionally restrain the spring guide against axial movement relative to the handle to avoid inadvertent flexing or relaxing of its distal end. The length of the stilening tube 82 is such that the distal end thereof will extend through the body 49 of the manifold 48 when the spring guide is attached to the handle.
When the handle and spring guide are connected the spring guide is led through the telescoping tube 46 so that the pellet 81 is retained within the back chuck C and the proximal end of the wire coil 77 and stilening tube 82 is clamped within the front chuck B. As the back chuck C is moved axially away from the front chuck B through operation of the linkage assembly E, tension is applied to the wire and it is axially displaced to fiex the distal end of the spring guide to the position shown in FIG. 8 by closing up the wedge-shaped spaces 78.
The total length of axial displacement of the tension wire 80 may be adjusted by varying the position of the tension screw 44 in the tension post 37 thus changing the axial spacing -between the back chuck C and the swivel 28.
During connection of the spring guide to the handle, its unexed distal end is passed through the spindle 58 of the manifold 48 and the manifold is then drawn along the spring guide toward its proximal end until the coupling halves 65 and 66 become engaged and the cap 67 can be secured on the boss 64 to complete the connection. The boss 64 carries a no-bleed plastic fitment (not shown) through which the spring guide passes and which serves to prevent back-How leakage of liquid from the manifold around the spring guide.
When these connections have thus been completed a suitable catheter can be drawn over the spring guide from its distal end and connected to the fitting S9 on the manifold 48. It should be noted that whenever the manifold is to be used for the injection of liquids when the spring guide is still retained within the catheter, the outside diameter of the spring guide must be suiciently less than the inside diameter of the catheter to permit free passage of liquid along the void therebetween.
It is believed that this invention, for the first time in medical and surgical technology, provides means for simultaneously manipulating a spring-guided catheter and injecting liquids therethrough.
When the manifold 48 is being used, the connections between the female Luer fittings 50 and the injection liquid supply sources prevent the manifold from rotating bodily although the spring guide and attached catheter may be rotated with respect thereto through use of the wheel D and its connected elements.
In the event that the manifold 48 is not to be used, it and the telescoping tube 46 are removed from the handle by releasing the pin vise 34 and replaced by a similar telescoping tube (not shown) having a catheter connecting fitting identical with the fitting 59 in place of the coupling half 66.
It is, of course, to be understood that variations in arrangements and proportions of parts may be made within the scope of the appended claims.
