Interconnections of implantable lead conductors and electrodes and reinforcement therefor
First Claim
1. An implantable lead comprising:
- a lead body extending from a lead proximal end portion to a lead distal end portion and having a lead intermediate portion therebetween, the lead body including one or more longitudinally extending lumens;
a cable conductor received in, and extending along, a first lumen;
an electrically conductive interposer having an inner surface coupled with the cable conductor and an outer surface, the interposer received, at least in part, in the first lumen; and
a tubular electrical contact co-axial with, and overlying portions of, the lead body;
wherein a first portion of a first lumen wall compressively urges the outer surface of the interposer, at least in part, through an interposer exposing aperture in a second portion of the first lumen wall toward an inner surface portion of the tubular electrical contact adjacent the cable conductor, such that a portion of the interposer is intermediately positioned between the cable conductor and the adjacent inner surface portion of the tubular electrical contact.

Abstract
An implantable lead comprises a lead body extending from a lead proximal end portion to a lead distal end portion. The lead body includes one or more longitudinally extending lumens. A conductor is received in, and extends along, a lumen. In varying examples, the implantable lead further comprises a tubular electrode co-axial with, and overlying portions of, the lead body. In one example, a lumen wall is sized and shaped to urge an electrically conductive interposer coupled with the conductor toward an inner surface of the electrode. In another example, a ring member is disposed within a lumen and the conductor is drawn and coupled thereto. In yet another example, an electrically conductive connector couples a first and a second conductor via grooves or threads. In a further example, an axial support member couples a distal end electrode and the lead body. Methods associated with the foregoing are also discussed.

18. A method of manufacturing an implantable lead, the method comprising:
-
forming a lead body extending from a lead proximal end portion to a lead distal end portion and having a lead intermediate portion therebetween; forming one or more longitudinally extending lumens within the lead body, including forming a first lumen having; a first lumen wall portion sized and shaped to urge a tubular electrically conductive interposer toward an inner surface of a tubular electrode co-axial with, and overlying portions of, the lead body, and a second lumen wall portion comprising an interposer exposing aperture sized and shaped to allow electrical connection between the tubular interposer and the tubular electrode; drawing a conductor into and through the first lumen; inserting the tubular interposer, at least in part, into the first lumen, including placing the tubular interposer over the conductor and positioning a portion of the tubular interposer intermediate the conductor and an inner surface portion of the tubular electrode adjacent the conductor; and coupling the tubular interposer to the conductor. - View Dependent Claims (19, 20, 21, 22, 23, 24)
