    摘要: Techniques for recharging a rechargeable power source coupled to a secondary coil implanted within a living body are described. In one embodiment, a recharging device external to the living body induces a sequence of pulses in a primary coil that is coupled to the secondary coil. The sequence includes high-amplitude pulses alternating with low-amplitude pulses, each high-amplitude pulse having an amplitude selected to transfer charge to the rechargeable power source during times of poor coupling between the primary coil and the secondary coil, each low-amplitude pulse having an amplitude selected to transfer charge to the rechargeable power source during times of good coupling between the primary coil and the secondary coil, and wherein the sequence of pulses is selected to prevent a violation of a limiting condition such as heating that is associated with recharging the rechargeable power source when recharging occurs in an open-loop manner.

    摘要: Techniques adapted for use with recharging a rechargeable power source of an implantable device. One aspect relates to providing a flexible primary coil that can be transcutaneously coupled to a secondary coil of the implantable device. Multiple adjacent turns of the coil are grouped via lacing to form bundles. The bundles have at least one dimension that is selected to be a same size as a predetermined thickness of the coil. In one embodiment, the dimension is a diameter of the bundle. In another embodiment, the dimension is at least one of a length or width of the bundle. Insulating overmolding may be provided over the coil. In one embodiment, the resulting antenna structure is bidirectional such that substantially the same performance characteristics are obtained during recharge regardless of which of two major surfaces of the antenna is placed in proximity to the patient.

    摘要: A charging system is disclosed. In one embodiment, the system includes a charging unit having a primary coil, and an implantable medical device comprising a secondary coil to receive charge from the primary coil. The implantable medical device further includes a half-wave voltage-doubling rectifier coupled to the secondary coil, a full-wave rectifier coupled to the secondary coil, and a rechargeable power source. Control logic is provided to periodically configure the rechargeable power source to receive charge from a selected one of the voltage-doubling circuit and the full-wave rectifier in a manner that increases rate at which charge is transferred from the secondary coil to the rechargeable power source. The control logic may configure the rechargeable power source to receive charge based on one or more monitored conditions which may include, for example, an indication of a current, a voltage, a coupling coefficient, back-scatter, and temperature.

    摘要: Devices, systems, and techniques for managing heat generated in coils for wireless energy transmission are disclosed. Inductive coupling between two coils may be used to recharge the power source of an implantable medical device. A phase change material may be thermally coupled to a flexible coil to absorb heat generated during the inductive coupling and reduce temperature increases of the flexible coil. The flexible coil may be configured to at least one of transmit energy to or receive energy from a second coil, and the phase change material may be configured to deform with the flexible coil and absorb heat from the flexible coil. The phase change material may be contained within thermally conductive tubes or channels configured in shapes that promote flexibility of the flexible coil.
