DISTRIBUTED TRANSFORMER

摘要

Disclosed is a distributed transformer or extension cord component for a transcutaneous energy transfer system used to transfer electric power to an implanted medical device. The extension cord component may enable power transfer to occur at various points on or near the body of the subject within whom the medical device is implanted. In this way, the subject may gain greater flexibility and high levels of convenience in connection with use of the transcutaneous energy transfer system.

主权项

1. A distributed transformer of a transcutaneous energy transmission device, the distributed transformer component comprising
a first transformer including a primary winding and a secondary winding, the primary winding associated with a power supply, the first transformer configured to transfer power from the primary winding to the secondary winding across a first boundary; a second transformer including a primary winding and a secondary winding, the secondary winding associated with a medical device implanted within a subject, the second transformer configured to transfer power from the primary winding to the secondary winding across a second boundary that includes at least the skin of the subject; and a cord that connects the secondary winding of the first transformer to the primary winding of the second transformer.
