Dialysis catheter with stiffening member and flow diverting structure

摘要

Disclosed is a double lumen continuous flow dialysis catheter having contiguous lumens of different lengths, the shorter lumen acting as a blood intake lumen and the longer as a blood return lumen. The catheter is designed to ease insertion into the body without the use of a tearaway sheath and to minimize recirculation flow from the blood return lumen to the blood intake lumen and/or prevent the blood intake lumen from becoming compressed against a vessel or body wall during dialysis.
