TRANSCUTANEOUS ENERGY TRANSFER SYSTEMS

摘要

The present disclosure relates to an improved transcutaneous energy transfer (TET) system that generates and wirelessly transmits a sufficient amount of energy to power one or more implanted devices, including a heart pump, while maintaining the system's efficiency, safety, and overall convenience of use. The disclosure further relates one or more methods of operation for the improved system.

主权项

1. A transcutaneous energy transfer system comprising:
(a) an internal component comprising a power-consuming device and an internal coil electrically connected to the power-consuming device, the internal component being adapted for mounting within the body of an animal; (b) an external coil adapted for mounting outside of the body; (c) a coupling detection circuit operative to provide an indication of whether or not the external coil is electromagnetically coupled to the internal coil; and (d) a drive circuit operative to apply a power-level alternating potential to the external coil responsive to an indication from the coupling detection circuit that the external coil is electromagnetically coupled to the internal coil, and to apply a test-level alternating potential less than the power-level alternating potential to the external coil when the not applying the power-level alternating potential.
