Implantable medical device with external housing for a recharging coil
First Claim
1. An implantable medical device adapted to be charged with an external recharging coil, comprising:
- a housing having an interior cavity, a proximal face, and an electrical feedthrough;
electronics carried in the housing interior cavity, the electronics configured to perform a medical therapy;
a rechargeable power source carried in the housing interior cavity and electrically coupled to the electronics; and
,a recharging coil having a major plane and being centrally located and substantially carried exterior to the proximal face of the housing and electrically coupled through the housing electrical feedthrough to the electronics and rechargeable power source, the proximal face of the housing being co-planar with the major plane of the recharging coil.

Abstract
A rechargeable implantable medical device with an external recharging coil carried on the medical device proximal face. The recharging coil can be attached to the medical device housing physically, or chemically, or a combination of both physically and chemically. The recharging coil electrically couples through housing electrical feedthroughs to electronics configured to perform a therapy and a rechargeable power source both carried inside the medical device housing. Additionally methods for attaching the external recharging coil to an implantable medical device are disclosed. The rechargeable implantable medical device can be a medical devices such as a neuro stimulators, drug delivery pumps, pacemakers, defibrillators, diagnostic recorders, cochlear implants, and the like.
