Spacers for use with transcutaneous energy transfer system

摘要

A transcutaneous energy transfer system, method and kit for an implantable medical device having componentry for providing a therapeutic output and a secondary coil operatively coupled to the componentry and is adapted to be implanted at a location in a patient. An external power source has a primary coil contained in a housing. 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. A holder is adapted to be externally positioned with respect to the patient at a spot in proximity of the location of the implantable medical device and secured at the location. A spacer, removably coupled to the holder, has an opening receiving the protrusion. A plurality of spacers can be used. The number is spacers is selectable based on the size of the protrusion.
