Abstract: A contact component of an implantable medical device connector module assembly includes a threaded bore in fluid communication with a connector bore thereof, and a flanged bore in fluid communication with the threaded bore. A perimeter surface of the flanged bore creates a shutoff with a pin during injection molding to form an insulative body of the assembly, and a perimeter surface of an insulative bore formed around the pin is preferably flush with that of the flanged bore of the contact component. A centerline axis of the flanged bore is preferably aligned with that of the threaded bore, for example, so that the molded insulative bore has a centerline axis aligned with that of the threaded bore of the contact component.

Abstract: An implantable medical device includes two conductive enclosures that are attached together, wherein the first enclosure contains electronics, and the second enclosure contains a power source. The second enclosure, all or a portion of which is located outside the first enclosure, includes an inner layer, an outer layer, and a header plate, all of which are configured to provide redundant sealing for the power source. The inner and outer layers, formed by separate metal sheets nested one within the other, are preferably in direct mechanical and electrical contact. The first sheet, which forms the inner layer, approximately conforms to a profile of the power source, located therein, and the second sheet, which forms the outer layer, conforms to a profile of the first sheet. An insulative housing, which contains connector contacts of the device, is directly secured to the first and second conductive enclosures, for example, by mounting brackets.

Abstract: 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.

Abstract: Methods for forming an insulative body of an implantable medical device connector module assembly employ an injection molding process, whereby first and second shots of insulative material form core and an overlay portions, respectively. In some methods, a panel portion of an electrical component is mounted between opposing surfaces of a mold such that a finger-like portion of the component extends into a cavity of the mold, with a first side thereof touching another surface of the mold and a second, opposite side exposed within the cavity; following first shot injection, the core portion captures the finger-like portion in relatively rigid relation thereto. When two types of connector bores are formed, a color indicator may be engaged with a feature of the core portion that is located in proximity to a connector bore of the first type, and then the overlay portion is formed over the indicator.

Abstract: A battery having an electrode assembly located in a housing that efficiently utilizes the space available in many implantable medical devices is disclosed. The battery housing provides a cover and a shallow case a preferably planar, major bottom portion, an open top to receive the cover opposing the bottom portion, and a plurality of sides being radiused at intersections with each other and with the bottom to allow for the close abutting of other components located within the implantable device while also providing for efficient location of the battery within an arcuate edge of the device. The cover and the shallow case being substantially hermetically sealed by a laser weld technique and an insulator member disposed within the case to provide a barrier to incident laser radiation so that during welding radiation does not impinge upon radiation sensitive component(s) disposed within the case.
