CLINICAL APPLICATION OF TH-7 VENTRICULAR ASSIST DEVICE

Abstract

An newly developed total VAD, which is more practical and proper for mass-production, have been evaluated. This new VAD system is parted into the sac and outer case, inflow and outflow cannulae, and their prosthetic valve built in connectors. Therefore, when we find the partial accident in VAD system, we can exchange only the accidental part. Durability test in the mock circulation and chronic animal experiments using adult goats were performed. THe results show that our VAD system has good property of hydrodynamics and antithrombogenecity and durability. We conclude that our VAD system can be useful for clinical application.
