1. A medical implant, comprising:
- a prosthetic hearing implant having a power management system, a power supply comprising;
a first rechargeable battery, and at least one further rechargeable battery;
a switching means, wherein each battery independently provides power to said hearing implant through said switching means; and
a management means for controlling said switching means, wherein said switching means has the capability to place said power management system in a first state where said prosthetic hearing implant draws power from only said first battery and has the capability to place said power management system in at least a further state where said prosthetic hearing implant draws power from only said at least one further battery, and wherein the power supply provides power to the prosthetic hearing implant.

Abstract
A power management system for a power supply (43) providing power to electrical equipment, such as a totally implantable prosthetic hearing implant (40). The power supply (43) can comprise a first rechargeable battery and at least one further rechargeable battery that each independently provide power to the implant (40) through a switching means. The management system comprises a management means for controlling the operation of the switching means to place the system in a first state where the implant (40) can draw power from only the first battery or at least in a further state where the implant (40) can draw power from only said at least one further battery.

2. An implantable tissue-stimulating prosthesis comprising
a power supply comprising: -
a first rechargeable battery, and at least one further rechargeable battery;
a switching means, wherein each battery independently provides power to said prosthesis through said switching means; and
a power management system for said power supply, wherein said management system comprises a management means for controlling the operation of said switching means, wherein said switching means places said power management system in a first state where said prosthesis draws power from only said first battery and wherein said switching means places said power management system in at least a further state where said prosthesis draws power from only said at least one further battery, wherein said prosthesis draws power from said power supply, and wherein said power supply is implantable with or in said prosthesis. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
