Valve operated catheter for urinary incontinence and retention
First Claim
1. A valve operated catheter for urinary incontinence and retention comprising a flexible duct (2) for insertion into a patient'"'"'s urethra and having a spiral shaped distal portion (12) for insertion inside a bladder, said distal portion provided with a plurality of holes (16) for the outflow of urine from the bladder to said duct, said catheter comprising:
- a seat (21) provided at an end of the catheter that remains outside of a penis;
an elastically deformable valve (20) provided with a slit (22) that is normally closed, said valve (20) being housed inside said seat (21);
two winglets (25) fixed at the end of the duct (2), the winglets placed outside of the penis for resting against the top of the glans, such that the patient pressing on the winglets causes the deformation of the part of said duct (2) correspondent to said seat (21), and of said valve (20) until the slit (22) opens.

Abstract
A valve operated catheter for urinary incontinence and retention comprises a flexible duct (2) designed to be inserted in the patient'"'"'s urethra, the catheter provided with a spiral shaped end portion (12), having a plurality of holes (16) for the passage of urine. The duct 2 is provided, at its other end, with a seat (21) in which there is housed a valve (20) made of elastic material, the valve being usually closed because of the elastic action. The valve (20) may be operated by the patient through light compressive action on two winglets (25) which are fixed to the end of the duct near to the valve, the winglets positioned symmetrically to the longitudinal axis of the same valve, outside the top of glans, so as to cause the opening of the passage (22) through elastic deformation of the valve (20).
