Abstract

Prosthesis consisting of a mesh material impregnated with an antibiotic, antiseptic, antispore medication or a combination of these which surrounds a conduit leading to the skin, such as the urethra, and having an end portion thereof embedded in a waterrepellent substance which protrudes from the end of the conduit and the surface of the skin and a cap therefor.

Claims

2. Prosthesis defined in claim 1 comprising a tubular fibrous mesh extending throughout substantially the entire longitudinal extent of said member and defining alone said one end portion and a water-repellent and nonporous coating extending substantially entirely over a longitudinally extensive portion of said mesh to define therewith said other end portion.

3. Prosthesis defined in claim 2 together with a solid waterproof removable closure closing said other end for precluding the flow of bodily fluids therethrough and removable to permit the passage of bodily fluids therethrough.

4. Method of treating urinary incontinence comprising, at least the steps of, freeing the end portion of the urethra of a patient from the surrounding skin, positioning a prosthesis comprising a bodily flexible tubular member, one end of which comprises a nonreactive material into which tissue can grow and the other end of which comprises a water-repellent, nonporous material with said one end portion thereof disposed within the incision and surrounding the end portion of the urethra and with the other end portion thereof protruding generally axially of the end of the urethra and from the surface of the surrounding skin;

permitting of the tissue to grow into said one end; and

selectively plugging and unplugging said other end portion of the prosthesis to control urinAtion.

5. Method defined in claim 4 further comprising, at least the additional step of, suturing said one end portion of said prosthesis in position during implantation.
