Intermittently wholly indwelling, user-actuated, continually-retained, valved urinary catheter

Abstract

Problems associated with prostate enlargement can be negated by using the present valved catheter. Such can be inserted and removed by the user. The catheter is retained in place by a flexible, foldable tee bar attached to the valve plug, which in turn is attached to a stretchy Nylon line. To actuate the valve, the plug can be pulled out of the upper catheter simply by pulling on the distal end of the catheter, allowing urine to drain. When the user has an erection, the penis engulfs the entire valved catheter. That helps to assure that reproductive functions will not be affected.

1 . A flexible plastic, valved catheter held in place within the bladder by a foldable, plastic tee bar tube that is attached through a stainless steel wire bail, which is attached to a rounded-end, rigid plastic tubing that constitutes the valve plug and which is glued and anchored to a stretchy monofilament line that keeps the valve plug seated within the conical shaped upper I. D. of the catheter until the user actuates the valve by pulling down on the distal end of the catheter, thus stretching the monofilament line, and yanking the valve plug out of the upper catheter I. D. so as to allow the discharge of urine from the bladder. 
     
     
         2 . A valved catheter, as in  1 , above, that retains the foldable plastic tee bar tube in a centered relationship under the stainless steel wire bail by the insertion of two, short, zee-shaped and rounded end, stainless steel wires which force the O. D. of said tee bar tube to be greater than the I. D. of the stainless steel wire bail that is holding said tee bar. 
     
     
         3 . A valved catheter, as in  1 , above, that is of sufficient length to protrude from the flaccid penis to allow easy valve actuation, but which will be engulfed into the urethra when the user has an erection, thereby allowing having normal sexual relations. 
     
     
         4 . A valved catheter, as in  1 , above, that is ergonomically pre-curved into the shape of a typical man's urethra, to reduce the lateral bending stresses from the installed catheter that could be painful to the user. 
     
     
         5 . A means of temporarily tying the stainless steel wires of  claim 2  together using monofilament line threaded through a thin-wall plastic sheath which can be untied after the valved catheter is past the bladder neck, simply by pulling on the monofilament line to release the knot, then removing the plastic sheath from within the flexible plastic catheter tube. 
     
     
         6 . A valved catheter as in  1 , above, that has no obstructions to the flow of seminal fluids along the smooth outside of the flexible plastic catheter tube, as will facilitate normal insemination.
