Portable medical power system
First Claim
1. A power system for powering an implantable medical device, comprising:
- an implantable battery pack including an implantable secondary battery and an implantable energy management system for controlling power to the medical device and to the secondary battery;
an implantable power inlet for receiving power to charge the secondary battery; and
nonimplantable power sources that are each configured to provide the power for charging the secondary battery to the power inlet without that power flowing from the power source to the power inlet through another one of the power sources,at least one of the nonimplantable power sources being a nonportable power source configured to be plugged directly into a wall socket,at least one other nonimplantable power source being chosen from the group consisting of;
a wearable power source configured to receive electrical power from the nonportable power source, and a power cart configured to receive electrical power from the nonportable power source.

Abstract
Disclosed is a medical power system for powering an implantable medical device including an implantable rechargeable battery pack, a wearable power source, a power cart, and an external power supply. The system may be used in three modes: 1) Fully disconnected (powered by implanted battery only); 2) Power provided by a wearable power source and/or a portable wheeled power cart via an inductive link, and 3) Nonportable power provided by a non-portable source such as an AC outlet with an uninterruptible power supply. The system includes automatic choice of the optimum source of power depending on the circumstances, and greatly increases “untethered time” a bionic-dependent patient may spend.
