Disclosed herein is an implantable electronic device. The device includes a housing and a header connector assembly coupled to the housing. The header connector assembly includes a DF4/IS4 assembly and a header including a bore. The DF4/IS4 assembly is locked within the bore via a locking datum arrangement that exists between the DF4/IS4 assembly and the header.

Implantable medical device with locking datum arrangement between DF4/IS4 assembly and header

In fabricating a header assembly of an implantable medical device, one end of a bore contact wire attached to a connector block is keyed with one guiding channel at an upper region of a feedthru adapter and through the adapter to its undersurface. An opposite end is bent into conformance with an orientation channel on the adaptor undersurface. A tip end of a feedthru wire connected to electronic circuitry of the medical device and projecting out of a casing mounting surface is bent for alignment with the orientation channel so end portions of the feedthru wire and bore contact wire are in end to end engagement, then welded together. A plastic header is molded to encapsulate the adapter, connector block, and bore contact wire and, when solidified, has an undersurface for engagement on the casing and an elongated receptacle aligned with a connector block bore to receive the lead.

Pre-molded header with universal tip-to-tip feedthru adaptor

An implantable medical device includes a sealed casing enclosing electronic circuitry and a plurality of electrical terminals connected to the electronic circuitry and projecting out of a mounting surface. A header has an undersurface for mounting engagement on the mounting surface of the casing and first and second oppositely directed elongated receptacles, the first receptacle being positioned proximate the electrical terminals. The header also includes at least one conductive connector block having a bore aligned with each of the first and second receptacles for receiving a proximal end portion of a lead extending through the elongated receptacle and carrying at least one electrical terminal and a wire electrically connects each of the connector blocks with an associated electrical terminal, at least the wire from the connector block associated with the first receptacle being of minimal length because of its close proximity to the plurality of electrical terminals.

Multi-directional bore configuration header

An implantable myocardial stimulation lead comprises a lead body having a distal end and a proximal end, and an electrical connector carried by the proximal end of the lead body. An electrode header carried by the distal end of the lead body has an axis and includes a helical fixation element extending along the axis, the electrode header having a surface configured to receive a driver for rotating the electrode header to screw the helical fixation element into the tissue of the heart. The lead body carries along its length a strain relief member resisting excessive bending of the lead body.

Myocardial lead and lead system

An electrical contact assembly comprises an annular housing defining an interior space, the housing including a tubular wall having an outer surface facing the interior space and an inner surface defining a central opening adapted to receive an electrical contact, the wall defining at least one aperture. Contained within the interior space of the housing is a garter spring having an inner diameter, the garter spring encircling the outer surface of the wall under preload so that a portion of the inner diameter of the spring projects through the at least one aperture into the central opening of the housing for engaging an electrical contact received within the central opening. An implantable medical device incorporating such an electrical contact assembly is also disclosed.

Electrical contact assembly

A connector assembly for an implantable medical device including a casing includes a header having a receptacle with an electrical contact for engageably receiving an electrical terminal on a proximal end of a lead and a fastener assembly for simultaneously releasably clamping the lead to the header within the receptacle and firmly attaching the header to the casing. The header is mounted on the casing and has a distal notched region with an upper surface and a first channel in its upper surface aligned with, and being a partial extension of, the receptacle. The fastener assembly includes a lead-lock component engageably received within the notched region of the header and with a second channel therein which is aligned and juxtaposed with the first channel, the channels taken together being an extension of the receptacle. A fastener system firmly mounts the lead-lock component to the header at the notched region.

Dual-locking mechanism for lead and header attachment in pre-molded headers

A connector assembly for coupling an electrical lead to an electrically energized device includes a non-conductive housing member with an elongated bore. A block member in the bore proximate the sealed end has a coaxial through bore. A first of multiple side by side pairs of seal assemblies and contact assemblies in the bore is proximate the block member, a last one is nearest the bore entrance. Each contact assembly has electrical commonality with a terminal of the device. A strain relief zone fixed to the housing member in the bore engages the last seal assembly and faces the bore entrance. Force on the strain relief zone toward the block member firmly seals in the bore all components defining a central passage coaxial with the through bore enabling electrical contact among multiple lead terminals inserted into the bore, an associated contact assembly, and an associated terminal of the device.
