Abstract

See full text

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.
