A capacitively loaded loop antenna for an implantable medical device is disclosed comprising a feed extending from a conductive surface of an implantable housing, a radiating element having a cross section larger than the feed, and a return coupling the radiating element to a conductive surface of the implantable housing. The radiating element can have a height above the top surface of the implantable housing, creating a capacitance between the radiating element and the conductive surface of the implantable housing configured to counteract the inductance of the capacitively loaded loop antenna.

Capacitively loaded implantable loop antenna

Implantable medical devices including interconnections having strain-relief structure. The interconnections can take the form of flexible circuits. Strain relief gaps and shapes are integrated in the interconnections to relieve forces in each of three dimensions. In some examples, the region of an interconnection which couples with a component of the implantable medical device is separated by a strain relief gap from a connection to a second component and/or a location where the flex bends around a corner.

The present subject matter provides feedthrough or interconnect systems for components of an implantable medical device and methods for their manufacture. A feedthrough system includes a wire or nailhead having a protruded tip. The wire or nailhead extends from an aperture in an encasement of a first component and is connected to a terminal conductor adapted to electrically connect to circuitry within the encasement. A ribbon wire has a distal end adapted to electrically connect to a second component and a proximal end having a pattern adapted to fit to the protruded tip of the wire or nailhead to provide for subsequent attachment of the ribbon wire to the nailhead.

Feedthrough system for implantable device components

The present subject matter provides apparatus and methods for manufacturing an encasement for a component of an implantable medical device having a main circuit board. The method includes forming an encasement aperture on a lateral side of the encasement. The lateral side of the encasement is adapted to be placed substantially parallel to a surface of the main circuit board. A feedthrough assembly is connected through the encasement aperture. The feedthrough assembly includes at least one terminal conductor at least partially passing through the encasement aperture.

Side mount feedthrough system for sealed components

Some examples of an electrical contact spring for an implantable medical device includes a housing, rigid and tubular in shape, defining a housing passage extending along a longitudinal axis, from a proximal portion including a proximal lip that defines a proximal opening, to a distal portion including a distal lip that defines a distal opening and a spring disposed in the housing, the spring tubular in shape and defining a spring passage concentric to the housing passage, the spring including: a distal ring portion disposed adjacent the distal portion of the housing and physically coupled to the housing, a plurality of spring elements coupled to and extending from the distal ring portion toward the proximal portion of the housing and a proximal ring portion disposed adjacent the proximal portion of the housing, cantilevered and suspended inside of and spaced apart from the housing by the plurality of spring elements.

An assembly integrating commercially available capacitors into filtered feedthroughs. A feedthrough assembly comprises a plurality of Input/Output (I/O) conductors, wherein the I/O conductors pass through a hermetic seal such that a first end of the I/O conductors reside on a non-hermetic side of the hermetic seal and a second end of the I/O conductors reside on a hermetic side of the hermetic seal, a printed circuit interconnect substrate residing on the hermetic side of the hermetic seal, and a plurality of ceramic chip capacitors mounted on the printed circuit interconnect substrate, wherein a first end of each capacitor is connected via the interconnect to the second end of an I/O conductor and a second end of each capacitor is connected via the interconnect to a constant voltage level.

Integrated electromagnetic interference filters and feedthroughs

A tape automated bonding (TAB) structure which includes a flex tape having a conductive lead pattern formed thereon. The conductive lead pattern includes a plurality of leads configured to form an inner lead bond (ILB) portion of the TAB structure. At least one of the plurality of leads is internally routed and has a contact exposed interior to the ILB portion of the TAB structure.
