  • Patent number: 10661088
    Abstract: An implantable medical device (IMD) has a housing enclosing an electronic circuit. The housing includes a shield member defining a first portion of an interior cavity of the implantable medical device and a skirted feedthrough assembly. The feedthrough assembly includes a shield extender having a top face and a sidewall that extends from the top face so that the top face and the sidewall are a single continuous component. At least one feedthrough aperture extends through the top face.

  • Patent number: 10632316
    Abstract: A one-piece electrical contact ring for use in a lead receptacle of an implantable medical device includes (i) a tubular body defining a cavity extending through the body and (ii) a plurality of resiliently deflectable elements extending from the tubular body into the cavity. The deflectable elements have a lead contacting portion configured to contact the lead when received by the cavity. The lead contacting portions of the deflectable elements in a relaxed state are located in a plane that intersects the tubular body and are configured to deflect along the plane towards the tubular body as the lead is inserted in the contact ring. The contact ring may further include a plurality of stops, each configured to (i) engage a stop portion of the elements when the elements are sufficiently outwardly deflected and (ii) inhibit further outward deflection of the elements when the stops engage the stop portions.

  • Publication number: 20200001007
    Abstract: The disclosure is directed to a pressure sensor of an implantable medical device. The pressure sensor may utilize detect fluid pressure based on a changing capacitance between two capacitive elements. The pressure sensor may define at least a portion of a fluid enclosure of the IMD. In one example, the pressure sensor has a self-aligning housing shape that occludes an opening in the pump bulkhead of the IMD. An operative surface of the pressure and the portion of the fluid enclosure may be formed of a corrosion resistant and/or biocompatible material. A first capacitive element of the pressure sensor may be a metal alloy diaphragm that deflects in response to external fluid pressure. A second capacitive element of the pressure sensor may be a metal coating on a rigid insulator sealed from the fluid by the diaphragm and a housing of the sensor.

  • Publication number: 20190329048
    Abstract: A method of manufacturing a hermetic lead connector includes fixing an electrically insulating ring between an electrically conducting contact ring and an electrically conducting spacer ring to form a hermetic ring subassembly, and fixing a plurality of the hermetic ring subassemblies in axial alignment to form a hermetic lead connector. The hermetic lead connector includes an open end, an outer surface, and an inner surface defining a lead aperture. The hermetic lead connector provides a hermetic seal between the outer surface and the inner surface.
