摘要

Disclosed are systems and methods for use of an inductive link for a communication channel in a transcutaneous energy transfer system.

主权项

1. A method of communicating data in a transcutaneous energy transmission device, comprising
transferring electrical power from an external primary to an implanted secondary by driving the external primary with a first time-varying electrical signal such that a second time-varying electrical signal is induced in the implanted secondary; encoding the first time-varying signal with a data signal by modulating an attribute of the first time-varying electrical signal as electrical power is transferred from the external primary to the implanted secondary; and receiving the data signal at the implanted secondary by demodulating the secondary time-varying electrical signal as electrical power is transferred from the external primary to the implanted secondary.
