An implantable medical device assembly comprises a sealed housing; a motor including a rotating output shaft within the sealed housing; a first coaxial shaft within the sealed housing, the first coaxial shaft being mechanically coupled to the rotating output shaft such that rotation of the rotating output shaft drives rotation of the first coaxial shaft; a second coaxial shaft external to the sealed housing, the second coaxial shaft being in axial alignment with the first coaxial shaft; an oscillating component mechanically coupling the first coaxial shaft to the second coaxial shaft, wherein rotation of the rotating first coaxial shaft drives the oscillation of the oscillating component, wherein the oscillation of the oscillating component drives rotation of the second coaxial shaft; and a flexible seal including the oscillating component. The sealed housing and the flexible seal combine to form a substantially sealed enclosure encasing the motor and the first coaxial shaft.

Mechanical feedthroughs for implantable medical device

A medical device lead connector includes electrically conducting contact rings spaced apart by an electrically insulating ring and in axial alignment. The electrically conducting contact ring and the insulating ring having an interface bond on an atomic level.

Diffusion bonded lead connector

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.

Methods of manufacturing a hermetic lead connector

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.

Electrical contact for implantable medical device

A medical lead may be fabricated using an electrode fixture ((A)-(D)) configured to facilitate circumferential and axial alignment between electrodes of the lead. In one example, a method includes positioning an electrode fixture around at least one conductor of a plurality of conductors () for a medical lead, wherein the electrode fixture at least partially retains an electrode assembly. The method also includes electrically coupling a portion of the at least one conductor with at least a portion of the electrode assembly at an attachment area defined by the electrode assembly when the electrode assembly is at least partially retained by the electrode fixture.

Structures and techniques for medical lead fabrication

Medical devices include stimulation and/or sensing circuitry that is interconnected to electrical components by a flexible circuit body having exposed portions of circuit traces that are attached to electrical contacts of the electrical components. Each circuit trace may span a separate window formed in an insulative body of the flexible circuit body, or a plurality of circuit traces may span a single window or may be freely extending from the insulative body. The exposed portion of the circuit trace may be plated with a conductive metal and then attached to the electrical contact of the electrical component. The flexible circuit body may be an extension from a flexible electrical circuit board containing the circuit. The circuit may be present on a circuit board that includes electrical contacts and where the flexible circuit body has exposed portions of circuit traces attached to the electrical contacts of the circuit board.
