APPARATUS FOR CONTROL OF URINARY INCONTINENCE Filed Oct. 18, 1960 INVENTOR JOHN L. BERRY atent lifihihiiti? Fatenteel Dee. 4t, 1962 hoe Filed Oct. 18, 1960, Ser. No. 63,308 3 Claims. ((11. l281) The present invention relates to the control of urinary incontinence, and, more particularly, is directed to a prosthesis and method of utilizing the same which will control undesirable leakages in the urethra of the human body.
in recent years an increasing amount of infection in the vicinity of the prostate gland has necessitated the removal of the same from the bodies of humans. in carrying out the operation by which the prostate or parts thereof are removed incisions are necessarily made which occasionally result in urinary incontinence after prostate removal. T his urinary incontinence is inconvenient, unsantitary and often psychologically demoralizing and depressing to the patient.
Several operative techniques and methods have been proposed and carried out in attempts to correct urinary incontinence. None of these however has been completely satisfactory. Among tie methods which have been used in attempts to control urinary incontinence are the operations of revision, compression, constriction and support. in the revi n tchnique a vesicle neck or urethral stenosis is created by incision or wedge excision. In the constriction method muscular constriction is use to create an artificial sphincter by Gracilis transplant or stenotic constriction. The operation of support utilizes plication procedures in which the transverse perineal muscles, ischiocavernosus and the levator ani muscles are used. The operation of compression applies a pressure to the urethra by means of a sling of muscular or fascial origin which does not completely surround the urethra. It is with this latter type of approach to correction of urinary incontinence that the present invention is directed, is. the application of pressure to the urethra by kinking and constricting.
According to the method of the present invention substantially improved control of urinary incontinence can be provided by the utilization of a new and novel prosthesis and method of utilizing the same. The prosthesis is of simple design, durable, comparatively easy to use and results in a substantially improved control of flow in the urethra. in carrying out the process of the present invention an unexpectedly high rate of complete cure has been obtained with very slight morbidity and minimal complications. The technique of the present invention is such that it can be repeated several times if the initial implant of the prosthesis is not completely satisfactory. Moreover, the technique of the present invention can be utilized in many instances where other procedures have been tried to control incontinence and failed to produce the desired result.
it is accordingly an object of the present invention to provide a new method of controlling urinary incontinence.
it is another obiect of the present invention to provide a new and improved prosthesis for urinary incontinence control.
it is a still further object of the present invention to provide a prosthesis suitable for positioning in the bulbocavernosus muscle in a manner that will provide compression of the urethra.
it is a still further object of the present invention to provide a prosthesis suitable for kinking or angulating the urethra in a manner that will control urethral flow.
These and other objects and advantages are accomplished according to the present invention by positioning in a pocket created between the urethra and the bulbocavernosus muscle and inserting therein the prosthesis of the present invention which may be generally described as a small, inflexible, biologically inert article, having in the plan view a generally rectangular shape which includes a bottom surface having a urethra bearing surface, parallel to the transverse axis of the urethra, when positioned adjacent thereto, a generally curved upper or top surface and means to permit the prosthesis to be fixedly positioned in the desired position adjacent to the urethra.
A more complete description of the prosthesis of the present invention and the manner in which it is used will be apparent from the drawings and description which follows in which:
FIGURE 1 shows the top View of one embodiment of the present invention.

FIG URE 7 shows the prosthesis positioned in a pocket fashioned between the urethra and the bulbocavernosus muscle.
FIGURE 8 is a cross section of the lower extremities of the human body showing the prosthesis positioned in relation to the urethra.
The prosthesis of the present invention is constructed of hard, inflexible, biologically inert materials such as plastics, metals, alloys and the like which are more specifically described hereafter.
The prosthesis is shaped in one of several forms with variations depending on the particular shape of the anatomy in the vicinity in which the prosthesis is to be positioned.
In FZGURES 1-4 there are shown several forms of prosthesis of the present invention. In SURE 1 one form of the prosthesis is shown in plan view. it will he noted that in this view the prosthesis has a generally rectangular shape with curved surfaces and no sharp e res, including sides 2 which terminate in the curved portion, generally shown at 3. Prosthesis 1 as shown in FIGUPF 2 includes a base. or more particularly, a urethra bearing surface t and an upper curved su ac 5 terminating at the base at ti. The upper curved surface 5 increases to a maximum at d at which point the prosthesis has its maximum thickness. To posi tion the prosthesis a plurality of holes it ext 1d ".g from the upper curved surface through the urethra bearing surface l, are positioned around the periphery of the prosthesis. Holes it) vary in number, generally from a minimum of two to a maximum of about ten.
ln FEGURES 3 and 4 alternate embodiments of the prosthesis of FIGURE 1 are shown. FEGURE 3 is a cross sectional side view, similar to the View of the embodiment shown in FIGURE 2. This form of the prosthesis is generally identified as 11. Prosthesis ll includes a base or bottom 12, having fashioned thereon a generally curved urethra bearing surface 14. Bearing surface extends across the width of prosthesis Ill so that when the prosthesis is positioned with its long axis parallel to the long axis of urethra, bearing surface 14 will be perpendicular to the urethra.
Similar to the embodiment of FIGURES l and 2, prosing of the pocket crethesis 11 of FIGURE 3 includes a generally upper curved surface 136, terminating in the curved ends 18. A plurality of holes Z-tl, constructed similar to holes 19 of 2 are positioned at the periphery.
The prosthesis 21 shown in FIGURE 4 in cross sectional side view includes a base or bottom surface 27 having a urethra bearing surface 223 thereon, which, similar to'urethra bearing surface 14 of FIGURE 3, extends across the width of the prostl esis. It will be noted that the curvature of urethra bearing surface 28 is more gradual than the similar surface of the prosthesis of FIG- URE 3. Varying degrees of curvature of the urethra bearing surface 23 can be provided in the body portion depending on the extent of coverage and application of pressure desired on the surface of the urethra. In any event, urethra bearing surface 28, similar to surfaces 14 and 4, must have suificient width to extend across the kinked or distended width of the urethra when the prosthesis is firmly implanted against the same and exerting maximum pressure. Prosthesis 21 includes in the top thereof an indented or V shaped depression 24 to assist in seating prosthesis 21 around muscular extensions or protrusions that may exist at the site of prosthesis implantation. Similar to the embodiments shown in FIG- URES 2 and 3, means are provided at 3b to permit positioning of the prosthesis in position in the manner desired.
As has previously indicated it is necessary to fashion or shape the prosthesis in such a manner as to avoid sharp edges. It is also necessary that the prosthesis be prepared from materials which are biologically inert and provide sufficient strength to prevent the prosthesis from flexing once in position. Suitable materials include plastics of the methacrylate type and metals such as gold, silver, and platinum, as well as other inert metal alloys. it is of course preferable that the prosthesis be light in Weight without sacrificing strength so as not to unduly distort or distend the muscular structure in the vicinity of the urethra when the prosthesis is positioned. When using a methacrylate type material to construct the prosthesis it may be desirable to impregnate the same with bismuth or other similar materials to enhance radiant visualization of the prosthesis when the same is positioned in the body.
In utilizing the prosthesis of the present invention it is necessary to insert the prosthesis in a pocket prepared between the bulbocave'rnosus muscle and the urethra in a position substantially adjacent to the urethra. To accomplish this the patient is placed on the operating table in a Lithotomy position with the perineal region of the body prepared in a sterile manner as is accomplished in carrying out a conventional perineal operation including the positioning of a Lowsley Anterior Tractor. Referring now to FIGURE 5, a verticle incision, generally identified as 52, is made in the middle of the perineum, extending from the scrotal margin to a point about 3 cm. above the anal margin. The incision is deepened through the skin .31, the subcutaneous tissues and fat down to the colles fascia 48 which covers the bulbocavernosus muscle 5G. in accomplishing this and other incisions retractors shown at 56, 57, 6t) and 62 are used. Drains such as 58 are provided as needed.
By blunt dissection the ischiocavernosus muscle 52 on either side of the bulbocavernosus muscle is exposed. This exposure is more completely shown in FIG RE 6 in which the bulbocavernosus muscle is identified as Sf In this further incision additional retainers or re-tractors 6'9 and drains 55 are used. After the isochiocavernosus muscle 52 is exposed the fascia covering the bulbocavernosus 5t hereafter referred to as the bulbo, known as the colles fascia 48, is incised in the rnidline, vertically over the entire length of the bulbo 53. A transverse incision is made in the bulbo 5 about 1 /2 cm. from its distal attachment to the urethra.
At this point, mainly by blunt dissection, a pocket 66 is formed between the bulbo 5% and the urethra 76, as shown in FIGURE 8, using the handle of the scalpel. In accomplishing the pocket formation it may be necessary to cut a few of the fibres of the decussation where they joint the urethra. The pocket 66 is made as deep as pos sible by carrying the dissection to the posterior insertion of the bulbocavernosus muscle.
At this point the Lowsley Anterior Tractor is removed. A prosthesis is selected of the proper size and shape. The size and shape selected will of course depend on the size and shape of the pocket, the structure of the bulbo muscle and its relationship and position to the urethra. The selected prosthesis identified as 68 in FEGURE 7 then placed in pocket 66- oriented in such a way that the flat or bottom surface is positioned against the urethra with the longer axis of the prosthesis paralleling the urethra.
The selected prosthesis may utilize the embodiment such as FIGURE 3 when a very narrow point of contact between the urethra wall is available for pressure application. The embodiment shown in FIGURE 4 can be utilized when a broader area of contact between the prosthesis and the urethra is desired. However, the prosthesis generally shown in FIGURES 1 and 2 will be preferred since the maximum contact along the long axis of the prosthesis with the long axis of the urethra can be obtained.
Once in position and properly oriented with respect to the urethra, the prosthesis is fixed in position by means of four double strands of a suitable steel wire 70 with one strand looped through each hole 10 in the four corners of the prosthesis 68. The prosthesis is secured in the pocket 66 by passing the double suture of wire which is threaded on a curved needle through the bulbo 5th out through the isochiocavernosus muscle 52. One strand of wire is removed from the needle and passed through the ischiocavernosus muscle at a lower point and tied to its fellow.
This procedure is repeated on each of the four corners of the prosthesis. It is essential that the prosthesis be firmly anchored and immobilized in position. It has been found that the use of steel wire in the manner described above accomplishes the permanent positioning most adequately. However, other suitable means if available such as clamps fashioned into the body portion of the prosthesis can conceivably be used. Experience has shown however that the plurality of holes at the periphery of the prosthesis provides a most adequate means for immobilizing the prosthesis in the desired position. Positioning the prosthesis in this manner will permit kinkingand cornpresson of the urethra in a manner that substantially restores the normal functioning of the external sphincter.
After the prosthesis has been positioned the transverse incision of the bulbocavernosus muscle is closed in line with the incision using interrupted sutures of catgut in the conventional manner. Similarly the collesfascia 4-3 is closed in a vertical manner followed by closure of the subcutaneous tissues and finally the skin is closed. Suitable dressings and drains as necessary may then be applied.
As installed the prosthesis remains permanently fixed in the bulbocavernosus muscle functioning in such a manner that pressure applied by the prosthesis to the urethra will substantially eliminate urinary incontinence.
While the description of this invention has been undertaken with respect to specific embodiments shown which will generally have a length of from 25 to about 49 mm, a width of from about 15 to 25 mm. and a thickness of from about 0.3 to about 1.5 mm, it is to be understood that many variations thereof can be made without departing from the essential nature of the invention. Such variaeeaeer ations and departures are to be understood as coming Within the scope of this invention and are to be limited only by the claims appended hereto.
