  • External button processor with a rechargeable battery
    Patent number: 9227064
    Abstract: An external processor device is described for a hearing implant system. An external processor housing has a generally planar skin contacting surface and a central axis perpendicular to the skin contacting surface. A signal processor is located within the processor housing for developing an implant data signal. The processor housing also contains a transmitter coil for coupling the implant data signal across the skin to the implantable prosthetic system. A battery container forms an annular compartment around the central axis and contains a battery arrangement to provide electrical power to the signal processor and the transmitter coil.

  • Battery Ventilation for a Medical Device
    Publication number: 20130096646
    Abstract: A medical device is presented that includes an external portion adapted for placement external to the skin of a user. The external portion includes a battery pack for interfacing with at least one battery cell. The battery pack includes a housing, the housing defining air inlet and/or outlet holes such that fluid flow is enabled through at least a part of the housing. A micro-ventilation mechanism moves air through at least a part of the housing.
