Tensile Test to Ensure a Safety of Cannula Connection in Clinical Ventricular Assist Device (VAD)

摘要

A pneumatic driven ventricular assist device (VAD) is not only designed for short-term usage of a "bridge to recovery" (BTR) in cardiac function recovery, but also developed to apply as a "bridge to transplantation" (BIT) for cardiac transplant. However, in the latter, the VAD must be exchanged before its expiries of guarantee. In this research, the authors have investigated the connector's strength between connector and cannula, and safety during the VAD exchange.
