A lead assembly including a porous polyethylene cover. In an example, the cover includes sections that have differing pore sizes. In an example, a section of the cover near a distal end portion of a lead assembly includes pores that are large enough to allow tissue ingrowth. In another example, a lead assembly includes two or more polyethylene covers having different porosities.

Lead assembly with porous polyethylene cover

This document discusses, among other things, a lead assembly including a lead body, at least one conductor extending through the lead body, and a covering having varied material properties. In an example, the covering is made by forming pieces of material having varied material properties. In another example, the covering is made by varying parameters such as heat or tension during wrapping of a piece of material onto a lead assembly.
