Filed:

Dec 17, 2003

Appl. No.:

10/739436

Inventors:

Anna Barlow - Santa Clarita CA, US
Christopher Fleck - Marina del Ray CA, US
Buehl E. Truex - Glendora CA, US
Edward G. Rourke - Topanga CA, US

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61N 1/00

US Classification:

607 37, 607 36

Abstract:

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.

International Classification:

A61N 1/05

US Classification:

607130, 607125, 607129

Abstract:

The intrapericardial lead includes a lead body having a proximal portion and a flexible, pre-curved distal end portion. The distal end portion carries at least one electrode assembly containing an electrode adapted to engage pericardial tissue. The distal end portion further carries a pre-curved flexible wire member having ends attached to spaced apart points along the distal end portion of the lead body, the flexible wire member having a normally expanded state wherein an intermediate portion of the wire member is spaced apart from the distal end portion, and a generally straightened state wherein the wire member and the distal end portion are disposed in a more parallel, adjacent relationship so as to present a small frontal area to facilitate delivery into the pericardial space. The wire member re-expands to its normal state after delivery into the percaridal space to anchor the distal end portion of the lead body relative to the pericardial tissue.

International Classification:

A61M 25/00

US Classification:

604532, 604 9601, 604525, 604264

Abstract:

An introducer sheath is disclosed herein. The sheath includes a tubular body. The tubular body has a proximal zone, an intermediate zone and a distal zone. The proximal zone is generally straight. The intermediate zone extends from a distal end of the proximal zone and curves in a first direction. The distal zone extends from a distal end of the intermediate zone and curves in a second direction different from the first direction.

US Classification:

439668, 439218, 439669

Abstract:

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.
