Abstract

An active implantable medical device (AIMD) is described. The AIMD has a rechargeable electrical energy power source connected to a PCB assembly for powering the medical device. The AIMD can sense biological signals from a patient, or it can have at least two electrodes that provide stimulation therapy to the patient. An inductive charging coil housed inside an elongate device enclosure is connected to the power source. The inductive charging coil has winds of an electrically conductive wire or tape that wrap around the PCB. The winds of the inductive charging coil have an upper wind portion residing above the PCB and a lower wind portion below the PCB. Opposed curved ends of the inductive charging coil winds are continuous with the upper and lower wind portions. This structure provides the inductive charging coil with a length aligned along a longitudinal axis of the PCB. In that manner, the inductive charging coil occupies a space otherwise not used in an elongate cylindrical enclosure for an AIMD.
