    摘要: A medical electrical lead body having an outer surface and including at least one lumen having an inner surface treated with a silane surface modifying agent to form a three-dimensional, densely cross-linked lubricious coating over at least a portion of the inner surface of the lumen. The outer surface of the lead body also may be similarly treated. The lubricious silane coating may reduce the coefficient of friction of the coated surface of the lead body by as much as 80% when compared to an uncoated surface. A reduction in the coefficient of friction may enhance the stringing efficiency of a conductor through the lead body lumen and may enhance its abrasion resistance.

    摘要: A medical electrical lead comprises a flexible, elongate lead body extending along a longitudinal axis and having a proximal end and a distal end. A protective distal tip structure is disposed on the distal end of the lead body. The tip structure includes a plurality of compliant projections each extending distally from the distal end of the body in the direction of the longitudinal axis. The projections are configured to contact and bear against cardiac tissue when the lead is implanted, and are deformable under the action of an axially or radially directed force. The projections optionally include a coating over a substrate. The coating can include a hydrogel material and/or a pharmaceutical agent such as a steroid for reducing inflammation at the implantation site.
