Abstract
Implantable medical leads include at least one of a polymeric stylet tube and/or a distal backfill material that is softer than is conventional at least in the area where a stylet bend will cause a distal bend in the lead. The polymeric stylet tube provides for improved torsional and column stiffness during insertion while the softer distal backfill material reduces a whipping action to increase the steerability and control of the lead during insertion. The softer backfill material may be provided alone or in combination with a harder distal backfill material. The softer backfill material may be provided as an insert that is encapsulated by the harder distal back fill material or may be provided as a backfill material that exists in a position adjacent to the harder backfill material.
