Implantable device lead including a distal electrode assembly with a coiled component
First Claim
1. A medical device lead comprising:
- an insulative body having a proximal region with a proximal end, and a distal region with a distal end;
a connector coupled to the proximal end of the insulative body of the lead configured to electrically and mechanically connect the lead to an implantable pulse generator;
a conductor extending through the insulative body, a proximal end of the conductor electrically connected to the connector; and
a distal electrode assembly at a distal end of the insulative body, the distal electrode assembly including a proximal portion that is mechanically and electrically coupled to a distal end of the conductor, a distal portion, an electrode at the distal portion, and an intermediate portion located between the proximal portion and the distal portion, wherein the distal end of the conductor terminates at the proximal portion of the distal electrode assembly, the intermediate portion is formed by a coiled element that terminates proximally with a first electrical connection at the proximal portion and distally with a second electrical connection at the distal portion to electrically connect the proximal portion to the distal portion, and the conductor is electrically connected to the electrode via the proximal portion, the intermediate portion, and the distal portion.

Abstract
A medical device lead includes an insulative body having a proximal region with a proximal end, and a distal region with a distal end. The medical device lead also includes a connector coupled to the proximal end of the insulative body of the lead to electrically and mechanically connect the lead to an implantable pulse generator. The medical device lead further includes a conductor extending through the insulative body with a proximal end electrically connected to the connector. A distal electrode assembly at a distal end of the insulative body includes a proximal portion electrically coupled to a distal end of the conductor, a distal portion, and an intermediate portion. The intermediate portion comprises a coiled element electrically connecting the proximal portion and distal portion.
