  • Patent number: 10322288
    Abstract: 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.

  • Publication number: 20190060656
    Abstract: An implantable medical device (IMD) includes a housing that is configured to enclose internal components including at least a processor and a power source. The housing defines two major surfaces that are generally parallel to each other and one or more channels that are each configured to receive a lead and electrically couple the respective lead to the internal components, where each of the channels extend substantially straight in to the housing along an axis generally parallel to the two major surfaces. The housing may be configured to be mounted to a cranium of a patient such that at least one of the two major surfaces approximates a curvature of the cranium. The IMD may include one or more funneling walls that define a rounded and smooth transition from a sidewall of the housing to a surface that defines one or more mouths to the channels.

  • Patent number: 10045764
    Abstract: An external medical device generates a drive signal inductively coupled to an implantable coil from an external coil. A regulator module coupled to the implantable coil generates an output signal in response to the inductively coupled signal and a feedback signal correlated to an amplitude of the inductively coupled signal. A signal generator receives the output signal for generating a therapeutic electrical stimulation signal. The control module adjusts the drive signal in response to the feedback signal to control the electrical stimulation signal.
