Abstract
Official abstract text for this publication.
A TET system is operable to vary an amount of power transmitted from an external power supply to an implantable power unit in accordance with a monitored condition of the implantable power unit. The amount of power supplied to the implantable power unit for operating a pump, for example, can be varied in accordance with a cardiac cycle, so as to maintain the monitored condition in the power circuit within a desired range throughout the cardiac cycle.
First claim
Opening claim text (preview).
What is claimed is: 1. A circulatory assist device comprising: (a) a pump adapted for implant in a patient, the pump having an electric motor, the pump having a time-varying power demand which is adapted to vary with a cardiac cycle of the patient; (b) an implantable power unit adapted for mounting within a body of the patient, the implantable power unit having a secondary coil, a power circuit connected to the secondary coil for supplying power to the pump so that power applied…
