Abstract

Abstract A suprapubic catheter comprising, an elongated shaft having a drainage lumen extending therethrough, and a plurality of openings extending through the shaft and communicating with the drainage lumen. The catheter has a first elastic sleeve secured to the shaft in spaced circumferential zones and defining a first cavity beneath the first sleeve, with the first sleeve being located adjacent a distal end of the shaft. The catheter has a second elastic sleeve secured to the shaft in spaced circumferential zones and defining a second cavity beneath the second sleeve, with the second sleeve being located proximal the first sleeve, and with the openings being located intermediate the first and second sleeves.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 90 words
A method of performing a suprapubic procedure comprising the steps of: passing the shaft of a catheter through the abdominal wall of a patient's body until a distal portion of the shaft containing a first distal sleeve and a second proximal sleeve is located in the patient's bladder; inflating the first and second sleeves in the bladder with the inflated first sleeve preventing passage of the shaft into the urethra; and pulling the shaft proximally until the inflated second sleeve seals against the bladder to prevent leakage around the shaft.
