CATHETER DEVICE AND METHOD FOR INDUCING NEGATIVE PRESSURE IN A PATIENT'S BLADDER

摘要

A urine collection catheter is provided. The catheter includes: a conduit having an open distal end; a drainage tube positioned at least partially within the conduit; and a bladder superior wall support. The drainage tube includes one or more fluid ports or perforations for permitting fluid flow into a drainage lumen defined by the drainage tube. The bladder superior wall support includes a support cap and a plurality of support members extending from a proximal surface of the support cap through the open distal end of the conduit. The support cap is capable of being moved between a retracted position and a deployed position. In the deployed position, the distal end of the drainage tube is spaced apart from the support cap, such that the support cap supports portions of the superior wall of the bladder from occluding the one or more fluid ports or perforations of the drainage tube.
