Abstract: Systems, devices and methods allow inductive recharging of a power source located within or coupled to an implantable medical device (IMD) while the device is implanted in a patient. The IMD may include a rechargeable battery having a battery housing; a non-metallic substrate attached to the battery housing, wherein the non-metallic substrate and the battery housing form an outer housing of the implantable medical device; control circuitry formed on the non-metallic substrate within the outer housing of the IMD; a receive coil within the outer housing of the IMD, the receive coil configured to receive energy from outside of the outer housing of the IMD; and recharge circuitry within the outer housing of the IMD and coupled to the receive coil, the recharge circuitry configured to receive the energy from the receive coil, and recharge the rechargeable battery using the received energy.

Abstract: Medical devices include a separate enclosure that houses a battery and electrically isolates the battery from external conditions such as any metal enclosures and ultimately isolates the battery from body fluids. Thus, the separate enclosure attaches to a housing of a medical device and provides for modularity of the battery which allows, for instance, different size batteries to be used with the same medical device design. The separate enclosure further prevents stimulation current from leaking back to the battery housing by providing the electrical isolation.

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.

Abstract: Implantable medical devices include connector enclosure assemblies that utilize conductors that are electrically coupled to feedthrough pins and that extend into a can where electrical circuitry is housed. The conductors may be coupled to the feedthrough pins and to capacitor plates within a filter capacitor by an electrically conductive bonding material and as a single bonding event during manufacturing. The base plate of the connector enclosure assembly may also include a ground pin. Ground capacitor plates may be present at a ground aperture of the filter capacitor where the ground pin passes through so that the ground pin, a ground conductor, and the ground capacitor plate may be coupled. A protective cover may be provided for the connector enclosure assembly to enclose the conductors intended to extend into the can prior to the assembly being joined to the can. Conductors may be attached to a common tab that is subsequently removed.

Abstract: A lead connector assembly includes a lead receptacle, a sleeve, and a handle for coupling to a medical lead. The lead receptacle has an inner surface and an opening configured to receive the lead. The sleeve is deflectable by the inner surface of the lead receptacle. The sleeve has a distal end portion defining a first outer diameter to engage the lead in a locked position and a second outer diameter greater than the first diameter in an unlocked position. The handle is coupled to the lead receptacle and a proximal end portion of the sleeve to move the sleeve axially in both directions along the longitudinal axis relative to the lead receptacle. The lead connector assembly retains the lead in the locked position. The lead receptacle is couplable to a medical device housing.

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.
