Tóm tắt

BACKGROUND: The survival rate of LVAD recipients may be improved by eliminating the infection failure mode at the percutaneous lead entry site. Wireless powering through a Transcutaneous Energy Transfer System (TETS) is a promising solution for achieving this. However, automatic controls need to be employed to compensate for the variations in efficiency and power transfer due to changes in load and coil-to-coil gaps. METHODS: This article discusses the results of in vitro and animal models performance evaluation of an automatically controlled TETS for powering a Left Ventricular Assist Device. RESULTS: It was found that power up to 20 W could be transferred at an axial gap of 30 mm. A 5% variation in speed and a 2% change in flow rate are observed with the change in tissue thickness, in porcine carcass model. CONCLUSIONS: The LVAD could be operated at the required RPM irrespective of the change in axial positions.
