Wholly indwelling, valve-actuated, urinary catheter

Abstract

Temporary relief from urine retention often accompanying prostate gland enlargement can be had by catheterization. Conventional catheters extend through the sensitive tip of the penis, causing pain, and preventing sexual relations. This invention places a valve inside the urethra that has an attached, proximal catheter which passes through the prostate into the bladder. Such valve can be opened at will by applying finger pressure against the distal valve tip and pushing upward toward the prostate. The latter tip can be felt inside the urethra, near the juncture between the penis and the scrotum. With the valve in the open position, the bladder can be nearly fully voided, regardless of the degree of enlargement of the prostate. This efficient and easy drainage of the bladder can eliminate the need to endure the painful surgical enlargement of the prostate duct—which can cause an inability to father children, normally, and may cause incontinence.

1 . A urinary catheter having two, integral, bulged portions for retaining such in the proper position inside the prostate gland. 
     
     
         2 . A mechanical valve, open on the distal end, which attaches to the catheter and is contained within the urethra. 
     
     
         3 . A removable valved-catheter inserting tool that is comprised of a flexible tubing; threaded, hollow metal tip; and a hollow, knurled knob for screwing in, or removing, the insertion tube from the valve. 
     
     
         4 . A dissolvable, cone-shaped tip for the catheter to facilitate inserting such through an enlarged prostate gland. 
     
     
         5 . A hydraulic means for expelling the cone-shaped tip, as in  4 , above, using fluid pressure from a syringe. 
     
     
         6 . A valve, as in  2 , above, which can be opened at will simply by applying fingertip pressure at the base of the penis, near the scrotum, and pushing the palpable distal end of the valve upward toward the prostate gland. 
     
     
         7 . A valved catheter that eliminates the necessity for having any portion of such extend through the sensitive tip of the penis, thus allowing sexual relations. 
     
     
         8 . A valved catheter combination having smooth outer contours which will allow ejaculate to pass around such.
