Design and synthesis of blood-compatible polyurethane derivatives polydimethylsiloxane graft chains, or which are ionically or covalently heparinized, have been synthesized. The water contact angle of these polyurethane derivatives ranged from 0° to 110°..Heparinized polyurethanes were highly blood compatible. The other polyurethane derivatives were more blood co

A small-caliber vascular graft for aortocoronary artery graft with temporarily artificial and permane carotid arteries were obtained, soaked in distilled water, and then sonicated bring about cell destruction. In this way, a natural tissue tube composed of collagen and elastic laminae was obtained. The tube with a protamine sulfate solution inside was cross-linked with polyepoxy compounds, which m

Development of nutating centrifugal blood pumpd contamination through the shaft seal in direct motor drive. To overcome these problems, Baurmeister and Affeld proposed and developed a centrifugal pump with a.nutating (non rotating) impeller, the so-called tea spoon pump. However, a great reduction in hydrolysis is necessary with this pump. Pump

Technical considerations in the development of clinical systems for temporary and permanent cardiac ith a description of two ABIOMED systems: an extracorporeal system (“the BVS”) designed for short-term in-hospital use and an implantable system (“the VAS”) designed for longterm ambulatory use. In the last decade, temporary support to either or both ventricles has moved from the research laboratory
