Abstract
Abstract A method of controlling urinary incontinence in a male comprises implanting in the penis of the male a relatively rigid backup support against which the urethra can be collapsed, anchoring said backup support to prevent it from migrating, and exerting pressure upon only one side of the urethra to collapse and keep it closed against the backup support. The preferred backup support includes a groove which receives the neurovascular bundle and protects the major blood and nerve supplies of the penis from the adverse effects of pressure exerted on the urethra. Devices for practicing the method are also disclosed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
68 words
A method of controlling urinary incontinence in a male patient which comprises implanting into the corpora cavernosum of the patient's penis relatively rigid backup support means of biocompatible material against which the urethra can be collapsed, anchoring said means to prevent it from migrating and then exerting selective pressure upon only one side of the urethra to collapse it and keep it closed against the backup support means.
Claim 2
Independent Claim
68 words
A method of controlling urinary incontinence in a male patient which comprises implanting into the corpora cavernosum of the patient's penis relatively rigid backup support means of biocompatible material against which the urethra can be collapsed, anchoring said means to prevent it from migrating and then exerting selective pressure upon only one side of the urethra to collapse it and keep it closed against the backup support means.
Claim 3
Dependent Claim
33 words
The method of claim 1 in which the selective pressure is exerted upon only one side of the uretha by a balloon implanted in the penis which is inflated by an implanted pump.
Claim 4
Dependent Claim
23 words
The method of claim 1 in which the selective pressure is exerted upon only one side of the urethra by an external clamp.
Claim 5
Dependent Claim
100 words
A urinary incontinence device for a male patient comprising relatively rigid backup support means of biocompatible material for implanting in the corpora cavernosum of the penis of the patient to provide a support against which the patient's urethra can be collapsed, anchoring means for keeping said backup support means properly positioned in the penis, pressurizing means for selectively exerting pressure upon only one side of the urethra to collapse it and keep it closed against the backup support means and means for relieving the pressure exerted by the pressurizing means so that the urethra will open to permit fluid flow.
Claim 6
Dependent Claim
100 words
A urinary incontinence device for a male patient comprising relatively rigid backup support means of biocompatible material for implanting in the corpora cavernosum of the penis of the patient to provide a support against which the patient's urethra can be collapsed, anchoring means for keeping said backup support means properly positioned in the penis, pressurizing means for selectively exerting pressure upon only one side of the urethra to collapse it and keep it closed against the backup support means and means for relieving the pressure exerted by the pressurizing means so that the urethra will open to permit fluid flow.
Claim 7
Dependent Claim
30 words
A device of claim 4 in which the backup support means is a pair of rod-like members, each of said members having a cylindrical main body and an integral stem.
Claim 8
Dependent Claim
76 words
A device of claim 4 in which the pressurizing means for selectively exerting pressure upon only one side of the urethra includes an inflatable balloon, pump means for inflating the balloon with pressurizing fluid to cause it to expand to exert selective pressure against one side of the urethra, and valve means for controlling the flow of pressurizing fluid between the pump and the balloon and controlling the pressure in the balloon at a safe level.
Claim 9
Dependent Claim
13 words
A device of claim 4 in which the pump is a pressure bulb.
Claim 10
Dependent Claim
24 words
A device of claim 4 in which the pressurizing means for selectively exerting pressure upon one side of the urethra is an external clamp.
Claim 11
Dependent Claim
27 words
A device of claim 4 in which the backup support means consists of a pair of rod-shaped penile implants adapted to be implanted in the corpora cavernosum.
Claim 12
Dependent Claim
32 words
A device of claim 9 in which the pressurizing means is a balloon and a pump reservoir in one of the implants, said pump reservoir being connected by tubing to the balloon.
