- the balloon since the balloon is less defor able, there will be less of a tendency for the areas of the balloon to expand in those regions beyond the anatomic narrowing being treated, which remote expansion, in effect, minimizes the pressure internal to the balloon.
- the external surface of the expanded balloon is stiffer, there is a-greater tendency for the re ⁇ molded structure to conform to the predetermined cross-sectional configuration of the balloon.

STIFFENED DILATION BALLOON CATHETER DEVICE
S P E C I F I C A T I O N
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to balloons for catheter devices adapted to be used for angioplasty and/or valvuloplasty and, more particularly, to balloons having stiffening means to main¬ tain the shape of the balloon when in the expanded state.
Description of the Prior Art
Inflatable balloons are presently employed to dilate stenotic arteries (angioplasty) and to dilate stenotic cardiac valves (valvuloplasty). In these procedures, considerable force must be generated to dilate these stenotic arteries and valves, particularly if these arteries and/or valves are heav¬ ily ingrown with scar tissue or if they are calcified. Hence, the balloons used for these procedures are filled with liquid under high pressure, often as high as 5 atmospheres (75 p.s.i.).
Despite the use of such high pressures, dilation with these balloons may be less than desired and may not be adequate. One reason for this inadequacy is related to the irregularity of the stenotic structure on which the angioplasty or valvulo¬ plasty procedure is being performed. When the expanded balloon impinges on a local elevation, the elevation will distort the balloon which results in a very limited area of the balloon contacting the local point of irregularity or elevation and thereby greatly reducing the force that can be exerted by the contacting surface of the balloon on the irregular shape. For example, if a local irregularity is one-eighth inch by one- eighth inch at its point of highest elevation, the area of such elevation is one-sixty-fourth square inches. An internal pressure of 75 p.s.i. from the balloon on this area provides a
force barely more than one pound. Such a force may be far less than that required to dilate the stenotic orifice of an artery or valve.
Presently this problem is largely unsolved since the abil¬ ity of balloons to accept higher pressure is compromised by the limitation on the thickness of their skin in order to minimize their bulk so as to enable them to be inserted into the vascular system.
Balloon catheters with stiffeners have been constructed, but they do not address, let alone solve, the problems discussed above. Three patents dealing with stiffened balloons are:
Baskin 2,854,933
Valli 4,437,856
Rowe 2,078,686
Rowe, 2,078,686, shows a ribbed support surrounded by an inflatable balloon. The ribs do not inflate with the balloon.
Baskin, 2,854,983, shows a catheter employing an inflatable bag 24. The bag has strips 46 attached thereto. Inflation of the bag serves to "expand" the strips. This serves in turn to keep the area open for drainage. The strips, however, are totally unsuitable and are not intended to augment the stiffness of the contacting surfaces for the expanded balloon, nor to deliver any expansile or dilating forces upon expansion of the balloon.
Valli, 4,437,856, teaches a dialysis catheter which employs an inflatable portion and a rib structure, which ribs serve as passages for the dialysis fluid, alternatively as collectors for the returning liquid, and alternatively as unperforated supports.

DETAILED DESCRIPTION OF THE INVENTION
Figures 1 and 2 show a perspective view of a dilation balloon associated with a catheter for use in angio-valvulo- plasty procedures, generally indicated at 20. The device consists of a catheter, generally indicated at 30, and an expandable balloon, generally indicated at 40. The catheter 30 has a closed end 32 which is used as a probe for threading the catheter. The catheter could, of course, have a channel formed in it for the placement of a guide wire on which the catheter could travel. The external wall 34 of the catheter has a plurality of passages 36 therein for the passage of pressure fluid into the interior of the balloon 40. The balloon 40 consists of a skin 42 which is connected to the wall of the catheter at a tapered or arcuate front portion 44 and a tapered or arcuate rear section 48.
As seen from Figure 2, the balloon can be attached to the catheter wall by any convenient bonding method known in the art. For example, at the front section of the balloon 42, the balloon is tapered to a cylindrical section approximating the size of the catheter wall and is bonded to the wall by means of a bonding agent. The rear portion 48 of the balloon shows
another method for attaching the balloon to the wall of the wall of the catheter in which the end of the balloon is folded over so as to be inside the expandable chamber. As mentioned, various adhesives or other bonding agents or ultrasonic welding can be used as well as any other wellknown bonding means for attaching the balloon to the catheter section.
The middle portion 46 of the balloon is cylindrical in shape and of relatively uniform and continuous surface. This is the portion of the device which is intended to press upon the stenotic structure to dilate the same by expansion of the balloon. As seen in Figures 2 and 3, embedded in the skin 42 of the balloon is a stiffening member 50, which is intended to run the length of the cylindrical section of the balloon or the contacting section of the balloon. This need not necessarily extend from the arcuate front 42 to the arcuate rear 48; but could be shorter. In all likelihood, it would not be longer than the contacting surface, since the stiffening member should be straight in order to minimize the cross-sectional area of the balloon when in the unexpanded or contracted state. The stiffening members 50 have rounded corners 52 so that there will be no sharp edges that would tend to form stress concen- • tration points or initiate rips or stretches in the skin 42 of the catheter device. The skins are usually made from a rela¬ tively thin flexible but usually not elastic plastic.
As shown in Figure 4, it is possible to locate the stiffening member externally of the wall. In this case, a wall 442 of the balloon has a stiffening member 450 attached to one surface. The stiffening member 450 again has rounded upper corners 452 and also a rounded, but wider, bottom surface 454, which contacts the skin 442 of the balloon. The wider bottom surface tends to give a larger surface for adhering of the stiffening member 450 to the skin. The corners, again, are rounded in order to avoid deterioration of the skin by the corners of the stiffening member during the expansion or con¬ traction of the expandable chamber.
In Figure 4, the stiffening member 450 can be either on the inside or the outside of the skin. The stiffening members
when external to the skin can be internally or externally dis¬ posed with relation to the envelope of the balloon. The stiffening members can be made from any convenient inert sub¬ stance from an inert metal to a relatively rigid plastic such as delrin or rynite.
Referring to Figures 5, 6 and 7, these are different embodiments of stiffening members that are suitable for use in the stiffened balloon. Figure 5 is a T-shaped section, gener¬ ally indicated at 550, having square corners 552 on the sides and the bottom of the T. The purpose of the T leg 556 is to increase the stiffness to the stiffening member with a minimum of crosssectional area.
Referring to Figure 6, there is a channel-shaped stiff¬ ening member, generally indicated at 650, having rounded exter¬ nal corners 652 at the top surface 654 and the channel legs 656.
Figure 7 shows a stiffening member similar to Figure 4, generally indicated at 750, having a curved top 754 to conform to the desired arcuate shape of the external skin of the balloon when the balloon is expanded. The curved surface also adds rigidity to the stiffening member. The external corners 752 are again rounded on the arcuate top 754 and also on the short¬ ened descending leg 756 of the T.
It should be noted that the stiffening members shown in Figures 5, 6 and 7 can be mounted on the inside of the skin 442 and possibly embedded in the skin.
Figure 8 is a partial view similar to a portion of Figure 2, and shows the wall or skin of the balloon 842 with a series of stiffening members, generally indicated at 850. Running perpendicular or in a generally crosswise or angular direction to the length of the stiffening members are a plurality of strengthening fibers, generally indicated at 860. The fibers can be internally or externally positioned with relation to the skin or embedded or bonded to the wall, and help provide a res¬ traint to the skin so that higher pressures can be transmitted by the pressurizing liquid filling the balloon without ripping or otherwise rupturing the skin. The strengthening fibers can
be on the same side or opposite side of the skin from the stiffening members.
In Figure 9, we have an embodiment different from that shown in Figure 8 in that rather than having a plurality of fibers positioned at an angle to the axis or length of the stiffening members, we have a mesh of fabric which is adapted to coact with the skin of the balloon either externally or internally, or which could also be embedded in the skin to add strength to the skin so that the balloon can hold a liquid maintained at a greater pressure and thereby exert a greater force on the structure being treated the dilating procedure.
The mesh may be on the same side as the stiffening members or on the opposite side.
Figures 10 and 14 show perspective views of stiffening members which are tapered.
Figure 10 shows a stiffening member, generally designated as 1050, is rectangular in cross-section and has relatively parallel edges in the central portion of the stiffening member which is intended to make contact with the wall of the vessel being treated. The stiffening member tapers both in the width and thickness towards either end as shown in Figures 11, 12 and 13. The edges 1052 are rounded to minimize the likelihood of damage to the material forming the balloon during the expansion of the balloon or while the balloon is in its collapsed state.
The tapering of the ends of the stiffening member, as shown at 12 and 13, reduces the trauma on the balloon as the balloon moves from its central cylindrical shape towards the end of the balloon where it tapers down to be joined with the wall of the catheter. By having the ends of the stiffening members tapered, they are less rigid and therefore more able to conform to the shape of the balloon at the end of the stiffener thereby reducing the discontinuity of stiffness and/or flexibil¬ ity between the stiffener and the skin of the balloon.
Figure 14 and associated Figures 15, 16, 17 and 18 show a stiffening member similar to that shown in Figure 7 but tapered in much the manner as that shown in Figure 10. Here the stiff¬ ening member, generally indicated at 1450, has a T-leg 1456
which extends downwardly in the central portion of the catheter. The top portion 1454 is curved and parallel to the bottom section and the edges 1452 are rounded as those in Figure 7. As you move from the central or contacting portion of the catheter towards either end, the stiffening member tapers in thickness and in width in the same manner as that discussed in Figure 10 and its associated Figures. Accordingly, the stiff¬ ening T-member 1456 will taper into the bottom of the bottom surface 1458 of the stiffening member and then the stiffening member will taper in thickness and width as it goes towards the ends. The purpose of the tapering is similar to that discussed with respect to Figure 10.
It can be seen from the above that the use of the stiff¬ ening members will, in effect, amplify the force that will be exerted by the balloon on any surface irregularities in the structure being treated. By having a relatively stiff contact¬ ing surface, the force exerted by the balloon's contacting surface on the irregularity will be greater and therefore the force will be amplified. Additionally, since the balloon is less defor able, there will be less of a tendency for the areas of the balloon to expand in those regions beyond the anatomic narrowing being treated, which remote expansion, in effect, minimizes the pressure internal to the balloon.
Further, because the external surface of the expanded balloon is stiffer, there is a-greater tendency for the re¬ molded structure to conform to the predetermined cross-sectional configuration of the balloon.
Additionally, as mentioned, since greater pressures can be tolerated in a balloon of the present invention, a greater force can be applied against local irregularities during the dilation procedure to crack or otherwise remold the irregulari¬ ties which are present.
While several embodiments of the invention have been illustrated and described, it is apparent that many other variations that may be made in the particular design and con¬ figuration without departing from the scope of the invention as set forth in the appended claims.
