  • Publication number: 20200001094
    Abstract: Systems, devices and methods allow inductive recharging of a power source located within or coupled to an implantable medical device while the device is implanted in a patient. The implantable devices in some examples include a multi-axis antenna having a plurality of coil windings arranged orthogonal to one another. The multi-axis antenna configured to generate at least a minimum level of induced current for recharging a power source of the implanted medical device regardless of the orientation of a direction of a magnetic field imposed on the multi-axis antenna relative to an orientation of the implanted medical device and the multi-axis antenna for a given energy level of the imposed magnetic field.

  • Patent number: 10433737
    Abstract: In some examples, an implantable medical device (IMD) comprises an electrochemical cell compartment that may define a barrier between an inside of the compartment and an outside of the compartment. The IMD may include an electrically conducting pad. The IMD may comprise an electrically conducting pin coupled to the pad. The pad may include top and bottom sides. The pin may extend from the bottom side of the pad. The pad may be positioned outside of the compartment and the pin may extend through an aperture in the compartment from inside the compartment to pad positioned outside of the electrochemical cell compartment. The IMD may include an electrically insulating material surrounding the aperture and between the bottom side of the pad and the compartment. The insulating material may insulate the pad from the barrier and form a seal between the inside of the compartment and the outside of the compartment.

  • Publication number: 20190247669
    Abstract: Systems, devices and methods allow inductive recharging of a power source located within or coupled to an implantable medical device while the device is implanted in a patient. The recharging system/device in some examples includes a first electrical coil and a second electrical coil configured to generate opposing magnetic fields forming a resultant magnetic field within a recharging envelope located between the coils. A third coil of the implantable medical device may be positioned within the recharging envelope so that the resultant magnetic field is imposed on the third coil, causing electrical energy to be induced in the third coil, the induced electrical energy used to recharge a power source of an implantable medical device coupled to the third coil, and/or to power operation of the implantable medical device.

  • Patent number: 9543566
    Abstract: Miniature electrodes and electrochemical cells are disclosed. Such electrodes are made from forming an electrode mixture onto a current collector and distal end of a feedthrough pin such that the current collector and distal end of the feedthrough pin is encapsulated. The methods and electrode assemblies disclosed herein allow such electrode assemblies to be made free from the step of directly attaching a formed electrode to a feedthrough pin and thus simplifying assembly and decreasing size.
