ABSTRACT:
An intra-urethral catheter for a male patient, has a lumen (7) interrupted within the prostatic space (S) of the patient's urethra (U), by a blockage (8), and upper and lower by-pass openings (9, 10) through the catheter-wall (6) are located one above and one below the blockage (8). The upper opening (9) discharges urine collected from the bladder (B) to flush the prostatic space (S), and the lower opening (10) passes the urine back into the lower part (7″) of the lumen for discharge. In a modification, the length of the catheter below the sphincter (M) of the bulbar urethra and the external urethral orifice (O), is of membraneous form (11), and at the external urethral orifice (O) extends into a portion (12) for folding back over the glans (G). A ring (13) retains the folded-back portion (12) on the glans (G).
