A high rate battery having a coiled electrode assembly housed in a case that efficiently utilizes the space available in many implantable medical devices is disclosed. The battery case provides a planar surface opposite an arcuate surface 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 battery cases include at least three planar sides extending between a top and a base of the battery case, wherein the arcuate side is located directly opposite one of the planar sides. The battery case may form a prismatic solid shape with one arcuate surface and five planar surfaces. The batteries may include a coiled electrode assembly including an anode and a cathode; electrolyte; and a case liner containing the electrode assembly. The coiled electrode assembly can have an elliptical cross-section including two arcuate ends, wherein one of the arcuate ends is nested within an arcuate side of the case. The batteries are capable of delivering about 20 joules or more in about 20 seconds or less; and may also be capable of delivering about 20 joules or more at least twice in a period of about 30 seconds. Also included are implantable defibrillator devices incorporating the batteries and methods of manufacturing the batteries including drawing the battery case from metal.

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.

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.

An implantable medical device (IMD) may include at least two separate lead connection assemblies, each with electrical connectors for connecting implantable leads to the IMD. In some examples, a IMD may include a first therapy module configured to generate a first electrical stimulation therapy and a second therapy module configured to generate a second electrical stimulation therapy for delivery to the patient. The IMD may include a first lead connection assembly including a first electrical connector electrically coupled to the first therapy module and a second lead connection assembly including a second electrical connector electrically coupled to the second therapy module. In some examples, the first and second lead connection assemblies are distributed around the outer perimeter of the IMD housing.

Methods and apparatuses are provided for an electrical device that employs a feedthrough including a hermetic seal that seals an interior region of the electrical device. The electrical device includes an electrical contact disposed within the interior region of the electrical device, and a wire terminal that includes an encircled portion that is encircled by the feedthrough, and a first end that electrically connects with said electrical contact. When the electrical device is constructed, the first end of the wire terminal is coated with a conductive metal that is more resistant to oxidation than the wire terminal. The first end of the wire terminal is secured to the electrical contact using a mechanical device such as a crimping connector or a spring connector.

A device connector assembly includes a plurality of electrical contacts and a sealing member including a corresponding plurality of apertures; each electrical contact extends within a corresponding aperture of the plurality of apertures such that each contact is accessible for coupling with a corresponding connector element of a lead connector. The lead connector elements protrude from a first side of an insulative substrate of the lead connector, and may be coupled to the contacts of the device connector assembly by aligning each connector element with the corresponding aperture of the sealing member, and applying a force to a second side of the insulative substrate, opposite the first side, in order to press each connector element into engagement with the corresponding contact.
