Implantable medical power module
First Claim
1. An implantable power module comprising:
- a hermetically sealed biocompatible case;
an electrochemical energy storage device housed within said case;
a power management circuit housed within said case;
a couple for remotely communicating with said power module;
said couple electrically connected to said power management circuit;
and at least one connector for functionally interconnecting said electrochemical energy storage device to an implantable medical device.

Abstract
Disclosed is a medically implantable integrated biocompatible power module incorporating a power source (e.g., battery), a power management circuit (PMC), a magnetically inductive coupling system (MICS) for remote communication and/or inductive charging and a homing device for locating the implanted inductive charging coil. Three configurations are disclosed, each generally suitable for a specified range of energy capacities. The implantable power module (IPM) allows for improved design flexibility for medical devices since the power source may be located remotely and be recharged safely in situ. Special safety aspects may be incorporated, including endothermic phase change heat absorption material (HAM), emergency energy disconnect and emergency energy drain circuits. Communication (one or two way) may be carried out using the inductive charging link, a separate inductive pathway, or other pathway such as RF or via light waves. Homing devices and other means for precisely locating the IPM and/or MICS are disclosed.
