System and method for transcutaneous energy transfer achieving high efficiency
First Claim
1. A system for transcutaneous energy transfer in a transverse direction, comprising:
- an external power source having a primary coil being driven at a frequency selectable in the range between eight and twelve kiloHertz contained in a housing; and
an implantable medical device having componentry for providing a therapeutic output and a secondary coil operatively coupled to said componentry;
said external power source capable of providing energy to said implantable medical device when said primary coil of said external power source is placed in proximity of said secondary coil of said implantable medical device;
said external power source having a lateral positional adjustment for said primary coil;
said frequency of said external power source being frequency adjustable providing a frequency adjustment;
said positional adjustment and said frequency adjustment allowing, at least in part, said system to attain an efficiency of energy transfer from said external power source to said implantable medical device of at least thirty percent.

Abstract
A system and method for transcutaneous energy transfer and/or charging in a transverse direction. An external power source having a primary coil being driven at a frequency selectable in the range between eight and twelve kiloHertz contained in a housing. An implantable medical device has componentry for providing a therapeutic output and a secondary coil operatively coupled to the componentry. The external power source is capable of providing energy to the implantable medical device when the primary coil of the external power source is placed in proximity of the secondary coil of the implantable medical device. The external power source has a lateral positional adjustment for the primary coil. The frequency of the external power source is frequency adjustable providing a frequency adjustment. The positional adjustment and the frequency adjustment allows, at least in part, the system to attain an efficiency of energy transfer from the external power source to the implantable medical device of at least thirty percent.
