Appl. No.:

10/439201

Inventors:

Mark T. Marshall - Forest Lake MN, US

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N 1/05

US Classification:

607122

Abstract:

A medical electrical lead includes a first low voltage electrode adapted for intimate contact with tissue at an implant site, in order to provide pacing stimulation, and a second low voltage electrode positioned in proximity to the first electrode, isolated from the first electrode and adapted to function in conjunction with the first electrode to provide bipolar sensing of near-field signals. A porous layer is formed over the second electrode; the porous layer allows conduction therethrough while preventing contact between the second electrode and tissue in proximity to the implant site.

International Classification:

A61N 1/00

US Classification:

607127

Abstract:

An implantable lead includes a defibrillation electrode and a sensor coupled thereto. The electrode and sensor are positioned along a body of the lead such that, when a fixation element couples the lead to an endocardial surface of a right ventricle, the sensor is located in a high flow region and a portion of the defibrillation electrode is located in proximity to a right ventricular apex.

International Classification:

A61N 1/05

US Classification:

607122

Abstract:

A medical electrical electrode includes an elongated conductive coil located over a lead body, and a conductive polymer material in contact with the lead body and located between individual coils of the elongated conductive coil. In certain embodiments, the conductive polymer is a polymer (e. g. , silicone) implanted with a conductive filler (e. g. , carbon black). In certain embodiments, the conductive polymer material is generally isodiametric with an outer diameter of the individual coils of the elongated conductive coil. A medical electrical electrode is fabricated by sliding an elongated conductive coil over a length of a lead body, dispersing a conductive polymer on the helical coil, inserting a tubing over the elongated conductive coil, distributing the polymer material between individual turns of the elongated conductive coil, heating the tubing so the tubing shrinks around the elongated conductive coil, and removing the tubing.
