Abstract
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.
