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.
Claims95
A urethral prosthesis, comprising:
- (a) a first tubular element having a first diameter and including a distal portion with at least one drainage hole for receiving urine, a proximal end, and a lumen extending from the hole through the first tubular element to the proximal end, at least a portion of the first tubular element for residing in a urethra of a patient;
- (b) a bridge segment having a diameter smaller than the first diameter, extending from the proximal end of the first tubular element, and for passing through a urinary sphincter of the patient, the bridge segment including a lumen extending from the lumen of the first tubular segment and through the bridge segment to provide a permanent urine flow channel across and through the urinary sphincter;
- (c) a second tubular element for residing in a penile urethra of the patient, the second tubular element extending from an end of the bridge segment opposite the proximal end of the first tubular element and including a lumen extending from the permanent urine flow channel through the second tubular element;
- and
- (d) a valve disposed within the lumen of the second tubular element for controlling a flow of urine through the lumen of the second tubular element.
