Abstract

An artificial urinary sphincter (AUS) system that includes a clamp and an inflatable device. The clamp is configured to be disposed on a urethra and includes a first portion and a second portion biased together to compress the urethra. The inflatable device is coupled between the first portion and the second portion of the clamp and configured to be inflated to separate the first portion from the second portion and unclamp or open the urethra.

First claim

The invention claimed is:

1. An artificial urinary sphincter system, comprising:
a clamp to be disposed on a urethra and including a first rigid member and a second rigid member;
a first elastic member biasing a first end of the first rigid member together with a first end of the second rigid member;
a second elastic member biasing a second end of the first rigid member together with a second end of the second rigid member, the first and second elastic members combining to elastically bias the first rigid member and the second rigid member together to compress the urethra;
a first device coupled to the first rigid member and the second rigid member, the first device being inflatable to push the first end of the first rigid member away from the first end of the second rigid member; and
a second device coupled to the first rigid member and the second rigid member, the second device being inflatable to push the second end of the first rigid member away from the second end of the second rigid member;
wherein the first rigid member and the second rigid member are separated by inflating the first device and the second device.

2. The system of claim 1 , comprising:
a reservoir to hold a fluid; and
a pump to move the fluid from the reservoir to the first device to inflate the first device and push the first rigid member away from the second rigid member.

3. The system of claim 2 , wherein the first device is to be drained of the fluid and the first rigid member and the second rigid member are elastically biased together by the first elastic member to compress the urethra as the fluid flows out of the first device.

4. The system of claim 1 ,
wherein the first elastic device is coupled to the first rigid member and the second rigid member at one end of the clamp and the second elastic device is coupled to the first rigid member and the second rigid member at another end of the clamp to elastically bias together the first rigid member and the second rigid member.

5. The system of claim 1 , wherein the first device and the second device are inflated simultaneously to separate the first rigid member and the second rigid member.

6. The system of claim 1 ,
wherein the first elastic member is attached to the first rigid member adjacent to the first end of the first rigid member, and the first elastic member is attached to the second rigid member adjacent to the first end of the second rigid member, and
wherein the second elastic member is attached to the first rigid member adjacent to the second end of the first rigid member, and the second elastic member is attached to the second rigid member adjacent to the second end of the second rigid member.

7. The system of claim 6 ,
wherein the first device is attached to the first rigid member adjacent to the first end of the first rigid member, and the first device is attached to the second rigid member adjacent to the first end of the second rigid member, and
wherein the second device is attached to the first rigid member adjacent to the second end of the first rigid member, and the second device is attached to the second rigid member adjacent to the second end of the second rigid member.

8. The system of claim 6 ,
wherein the first device is attached to the first and second rigid members between the first elastic member and the second device, and
wherein the second device is attached to the first and second rigid members between the first device and the second elastic member.
