Establishing continuity between a shield within an implantable medical lead and a shield within an implantable lead extension
First Claim
1. An implantable lead extension, comprising:
- an extension jacket;
a tubular shield layer within the extension jacket; and
a non-conductive housing at a distal end of the extension jacket that includes an opening, a connector within the opening, the housing comprising a first layer of non-conductive material that surrounds the connector and a second layer of non-conductive material that surrounds the first layer of non-conductive material, wherein the tubular shield layer extends from the extension jacket between the first layer of non-conductive material and the second layer of non-conductive material, and wherein the tubular shield is conductively coupled to the connector, the tubular shield layer comprising a braid at least within the non-conductive housing.

Abstract
Implantable medical leads and implantable lead extensions include a shield. The implantable medical lead is coupled to the implantable lead extension. Stimulation electrodes of the implantable medical lead contact stimulation connectors within a housing of the implantable extension to establish a conductive pathway for stimulation signals from filars of the implantable extension to filars of the implantable medical lead. Continuity is established between the shield of the implantable medical lead and the implantable extension by providing a radio frequency conductive pathway within the housing. The radio frequency conductive pathway extends from a shield of the implantable extension to a shield connector that contacts a shield electrode of the implantable medical lead. The radio frequency conductive pathway may have various forms such as a jumper wire or an extension of the shield within the implantable extension.
