DEVICES, METHODS AND SYSTEMS FOR COUNTERPULSATION AND BLOOD FLOW CONDUIT CONNECTION

摘要

A blood flow conduit includes a first conduit portion defining a first portion of a lumen and blood flow path, and a second conduit portion defining a second portion of a lumen and blood flow path. The first portion of the lumen has a smoother surface for contacting the blood flow than the second portion of the lumen. A discontinuity such as a tip portion is positioned between the first and second portions of the lumen.
