Treating urinary retention
View Patent ↗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.
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.
