ADJUSTABLE-LENGTH DUAL-LUMEN HEMODIALYSIS CATHETER AND A METHOD FOR ITS USE

摘要

The present adjustable-length dual-lumen hemodialysis catheter can eliminate the need to stock various lengths of hemodialysis catheters and can provide a hemodialysis catheter, which can be trimmed to various lengths in order to precisely accommodate patients of various shapes and sizes. Specifically, the present adjustable-length dual-lumen hemodialysis catheter can comprise a cuff ring assembly, which can be secured at selected locations along the trailing limbs of the catheter allowing the cuff ring assembly to be installed in a location chosen to precisely fit a particular patient.
