摘要:
A connector assembly of a medical electrical device includes a plurality of electrical contacts, wherein at least one contact of the plurality of electrical contacts includes an electrical coupling receptacle. The electrical coupling receptacle of the at least one contact includes a first portion, which is adapted to receive a connector element of a medical electrical lead, and a second portion, in which a part of a feedthrough member extends, and to which the part of the feedthrough member is fixedly coupled.

IPG connector headers for implantable medical devices are provided. In one embodiment of the invention, an IPG connector header having a header bore for receiving and making electrical connection to a lead connector assembly of an implantable medical device comprises a non-conductive header base and a plurality of electrically conductive header connector elements disposed within the header base. A plurality of electrically insulative fluid seals are interposed between the header connector elements. Each fluid seal has a fluid seal bore and is formed from an elastomeric material and an additive. The additive is formulated to reduce the frictional forces required to insert the lead connector assembly through the fluid seal bores of the fluid seals.

A telemetry antenna for an implantable medical device includes one or more portions having a non-linear configuration. In some embodiments, the non-linear configuration provides an antenna having a greater antenna length than the linear lengthwise dimension of the antenna structure. In some embodiments, the non-linear configuration is a serpentine pattern.

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.

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.
摘要:
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.
