Implantable device lead including a distal electrode assembly with a coiled component
First Claim
1. A medical device lead configured to connect to an implantable pulse generator, the 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 the implantable pulse generator;
a conductor extending through the insulative body, a proximal end of the conductor electrically connected to the connector; and
a metal housing that at least partially houses a fixation helix, the housing having a proximal end and a distal end, anda coil extending around the housing, the coil having a proximal end that is distal of the proximal end of the housing, the coil further having a distal end that is proximal of the distal end of the housing.

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.
