Abstract: A medical device lead includes a tubular conductive element disposed over a lead body. The tubular conductive element includes at least one segment having one or more kerfs formed radially therethrough in a predetermined configuration so as to affect at least one electrical property, e.g., electrical impedance, of the segment. The segment may form a shocking conductor of the medical device lead. The tubular conductive element may alternatively include proximal, intermediate and distal segments each having one or more kerfs formed radially therethrough, where the one or more kerfs in each of the proximal and intermediate segments are configured so that these segments each have a higher electrical impedance than the distal segment. A layer of insulative material is disposed over the proximal and intermediate segments, so that the proximal and intermediate segments of the tubular conductive element are operable to filter electromagnetic energy from an external source.

Abstract: A medical device lead includes a flexible body having a proximal region with a proximal end, and a distal region with a distal end. A connector is coupled to the proximal end of the flexible body of the lead to electrically and mechanically connect the lead to an implantable pulse generator. The medical device lead also includes an electrode in the distal region of the flexible body, and a cable conductor having a proximal end electrically coupled to the connector and a distal end electrically coupled to the electrode. The cable conductor consists of a single helically coiled filar including a plurality of co-radial turns and having an outer diameter of less than about 0.020 inch (0.508 mm).

Abstract: Various embodiments concern shielding an implantable lead from RF energy associated with MRI scans. The lead can include a distal region, a proximal region, an intermediate region between the distal region and the proximal region, at least one electrode disposed on the distal region, and at least one conductor extending from the proximal region to the at least one electrode. Implanting of the lead can include coiling a portion of the intermediate region to define one or more loops and selectively shielding the one or more loops of the lead with a RF shield. The RF shield can comprise metallic material and can be configured to reduce RF signal coupling to the at least one conductor along the one or more loops.

Abstract: An active fixation lead may have a lead body formed at least in part from an inner member and an outer sheath. The inner member may include a pace/sense lumen and one or more cable lumens. The inner member may include one or more longitudinally extending crumple zones that are configured to reduce stress within the pace/sense lumen that could otherwise be caused by compressive forces applied to the lead.
