Compression implant for urinary incontinence
First Claim
1. A compression implant to resist flow of urine through the urethra comprising:
- a flexible cap; and
external pressure face on the cap;
a base;
a peripheral wall continuously interconnecting the cap and the base;
a peripheral fold in the peripheral wall enabling the face to move toward and away from the base by changing the shape of the fold without stretching the material which forms the wall;
the cap, base and peripheral wall defining an internal cavity;
fluid-like material in the cavity including the portion of the cavity contiguous to the base, whereby the spacing apart of the face and base can be determined by selection of the amount of said fluid-like material in the cavity, and the resistance of the cap to force exerted on the pressure face which tends to move it toward the base can similarly be determined.

Abstract
A compression implant to resist the flow of urine through the urethra comprising a cap, an external planar pressure face on the cap, a base, an external bearing face on the base, and a peripheral wall continuously interconnecting the cap and the base. A peripheral fold in the peripheral wall enables the face to move toward and away from the base by changing the shape of the fold without elastic stretching of the material which forms the wall. The cap, base and peripheral wall together define an internal cavity which can be filled with an adjustably variable amount of fluid whereby to adjust the firmness of the capsule and thereby to adjust the force which it exerts against the urethra after implantation.
