FLEXIBLE RECHARGE COIL TECHNIQUES
First Claim
1. A charging system adapted to charge a power source of an implantable medical device, comprising:
- a coil having multiple turns and being adapted to transcutaneously transfer an electromagnetic waveform to the implantable medical device;
lacing adapted to group the turns into multiple bundles, each containing a predetermined number of adjacent ones of the turns; and
a flexible overmolding formed over the coil.

Abstract
Techniques adapted for use with recharging a rechargeable power source of an implantable device. One aspect relates to providing a flexible primary coil that can be transcutaneously coupled to a secondary coil of the implantable device. Multiple adjacent turns of the coil are grouped via lacing to form bundles. The bundles have at least one dimension that is selected to be a same size as a predetermined thickness of the coil. In one embodiment, the dimension is a diameter of the bundle. In another embodiment, the dimension is at least one of a length or width of the bundle. Insulating overmolding may be provided over the coil. In one embodiment, the resulting antenna structure is bidirectional such that substantially the same performance characteristics are obtained during recharge regardless of which of two major surfaces of the antenna is placed in proximity to the patient.
