MULTIPLE-CABLE LEAD WITH INTERRUPTED CABLE AND CRIMP CONFIGURATION

摘要

Example implantable cardiac electrotherapy leads are disclosed herein. In an example, a lead may include a plurality of cable conductors within an insulating jacket. A first one and a second one of the conductors include a proximal end at a proximal end of the jacket, the second conductor extends to at least the distal end of the jacket, and the first conductor includes a distal end at an intermediate location between the proximal end and the distal end of the jacket. The lead may also include a crimp connector connected to the first one of the cable conductors at the intermediate location, as well as a conductive element that may be connected to the crimp connector. A number of conductors along the proximal portion of the jacket may be greater than a number of conductors along at least a segment of the distal portion of the jacket.

1. An implantable cardiac electrotherapy lead comprising:
a plurality of cable conductors; an insulating jacket defining at least one lumen extending from a proximal end to a distal end of the jacket, the plurality of cable conductors located within the at least one lumen, wherein a first one and a second one of the cable conductors comprise a proximal end at the proximal end of the jacket, the second one of the cable conductors extends to at least the distal end of the jacket, and the first one of the cable conductors comprises a distal end at an intermediate location between the proximal end of the jacket and the distal end of the jacket, the jacket comprising a proximal portion from the proximal end of the jacket to the intermediate location and a distal portion from the intermediate location to the distal end of the jacket; a crimp connector connected to the first one of the cable conductors at the intermediate location; and a conductive element connected to the crimp connector, wherein the conductive element is configured to administer an electrotherapy signal transmitted to the conductive element via the first one of the cable conductors; wherein a number of cable conductors along the proximal portion of the jacket is greater than a number of cable conductors along at least a segment of the distal portion of the jacket.
