摘要:
A connector assembly for effectuating electrical and mechanical coupling between an implantable device and a lead comprises a main body portion and a rotating lever which collectively define a socket for receiving the terminal end of the lead therein. When the lever is in an unlocked or open position, very little insertion force is required to introduce the terminal end of the lead into the socket. When the lever is rotated to its closed position, a J-groove connection between the lever and the main body portion causes the lever to be drawn toward the main body portion. This inward travel of the lever causes an annular sealing grommet in the connector assembly to be compressed around the circumference of the lead body, effectuating a frictional and fluid-tight connection between the lead and the implantable device. In another embodiment of the invention, compression of the sealing grommet is accomplished by pressing downward on a slide element. Complementary stepped-ramp bosses or protrusions on the slide element and main body of the connector assembly are such that as the slide element travels downward, it is simultaneously pulled inward slightly to compress the sealing grommet.

An implantable medical device includes a housing forming an internal cavity, the housing defining a profile with a height and a width and further defining a thickness perpendicular to its profile. The thickness of the housing is shorter than both the height and the width of the profile of the housing. The implantable medical device further includes at least one battery within the internal cavity, at least one capacitor adjacent the battery within the internal cavity, the capacitor and the battery being located along a common plane within the internal cavity, and circuitry within the internal cavity. The circuitry extends over both the battery and the capacitor within the internal cavity such that the circuitry is in a stacked arrangement relative to the battery and the capacitor.

Systems and techniques that enable a user to selectively extend the time prior to providing an indication of power source depletion, e.g., allow an extended the recommended replacement time (RRT) prior to providing an elective replacement indication (ERI), are described. The user provides input, which may indicate an acceptable level of implantable medical device performance, e.g., that lesser performance for a period between a default RRT and an extended RRT is acceptable. In response to the input, the time until providing an RRT/ERI notification, or some other indication of depletion of the implantable medical device power source, may be extended.

An implantable medical device is manufactured with a hermetically sealed housing and a modular assembly enclosed within the housing. The modular assembly includes a circuit board, an electronic component mounted on a top surface of the circuit board, and a wall formed having an outer surface and an inner surface separated by a top edge and a bottom edge, the wall bottom edge positioned against the circuit board such that the wall encircles the electronic component coupled to the circuit board. The wall top edge is coupled to the housing a ferrule in one embodiment.

A connector assembly of a medical electrical device includes a plurality of electrical contacts and an insulative base that supports the plurality of electrical contacts and extends between the plurality of electrical contacts and a housing of the device, and, wherein at least one contact of the plurality includes an elongate electrical coupling receptacle in which a first part of a feedthrough member extends, being fixedly coupled thereto. The feedthrough member further includes a second part and a bend, which is located between the first and second parts. The second part of the feedthrough member extends away from the contact and through a port formed in the insulative base adjacent to the contact.

Structures and methods relating to electrodes for incorporation into a feedthrough with a profile adapted for subcutaneous sensing of physiologic and cardiac signals. Electrode assemblies are adapted for integration with feedthroughs and provide reliable insulation from the implantable medical device housing. Various structures and manufacturing processes are implemented to provide a large sensing surface with a low profile. The subcutaneous sensing electrode assembly can provide a leadless sensing system and further enhances installation and follow-up procedures.
摘要:
A connector circuit assembly for use in an implantable medical device, and a method of making the assembly that includes a core portion formed of a thermoplastic material using either an injection molding process or a machining process. This core portion is adapted to be fitted with at least one electrically-conductive circuit component such as a connector member, a set-screw block, or a conductive jumper member. In one embodiment of the invention, the core portion includes multiple receptacles or other spaces that are adapted to be loaded with the various circuit components. The core assembly is positioned into a second-shot mold assembly, and a second thermoplastic material is injected into the mold so that the second thermoplastic material extends over and adheres to the core portion and the circuit component.
