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.
