Abstract
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.

A method of forming a polymeric cover over a portion of an implantable medical electrical lead component, the method comprising:
- wrapping a single piece of polymer material over a portion of the implantable medical electrical lead component to form a cover over the implantable medical electrical lead component, including controlling one or more parameters during the wrapping step such that the cover has a first portion having a first set of material properties and a second portion having a second set of material properties different than the first set of material properties.
A method of forming a polymeric cover over an implantable medical electrical lead component, the method comprising:
- wrapping a single piece of polymer material over the implantable medical electrical lead component to form a cover over the implantable medical electrical lead component, the single piece of polymer material including a first portion having a first set of material properties and a second set of material properties,
- wherein the first set of material properties is different than the second set of material properties such that the cover has varying material properties.
