Abstract

A urethral prosthesis provides relief of urinary retention and has first and second tubular elements with an interposed bridge segment. A valve can be disposed in the second tubular element to control the flow of urine therethrough.

Claims

1. A urethral prosthesis, comprising:

(a) a tubular element including a distal portion and a closed distal end, the distal portion defining a drainage hole for receiving urine from a bladder of a patient, the tubular element further including a proximal end and a lumen extending from the drainage hole through the tubular element to the proximal end, the tubular element further including a length defined between the proximal end and the distal end, the tubular element configured to maintain an open channel for fluid flow through a prostatic urethra of the patient when the prosthesis is positioned within the patient;

(b) an inflation balloon disposed on the tubular element;

(c) at least one suture extending from the proximal end of the tubular element, the at least one suture passing through a urinary sphincter of the patient when the prosthesis is positioned within the patient to allow the patient to control the urinary sphincter; and

(d) a non-inflatable element extending from a proximal end of the at least one suture, the non-inflatable element including a proximal end and a distal end and defining a length between the proximal end and the distal end, the length of the tubular element being greater than the length of the non-inflatable element, the distal end of the non-inflatable element having an outer diameter greater than an outer diameter of the proximal end of the non-inflatable element.

2. The urethral prosthesis of claim 1, wherein the non-inflatable element is configured to be disposed within a penile urethra.

3. The urethral prosthesis of claim 1, wherein the non-inflatable element has a width and is configured to substantially maintain the width during both insertion and while maintained within a urethra.

4. The urethral prosthesis of claim 1, further comprising at least one removal suture coupled to the non-inflatable element.

5. The urethral prosthesis of claim 1, wherein the inflation balloon is disposed near the drainage hole.

6. The urethral prosthesis of claim 1, wherein the tubular element comprises a pliable, biocompatible material.

7. The urethral prosthesis of claim 1, wherein the tubular element comprises silicone rubber.
