An implantable medical lead comprises an insulating lead body housing having
an
outer surface. A thin, flexible membrane surrounds the insulating housing, the
membrane having an inner surface confronting the outer surface of the housing.
A lubricious interface between the inner surface of the membrane and the outer
surface of the housing facilitates movement of the insulating housing relative
to the membrane in response to frictional engagement of the membrane with adjacent
structure. Also disclosed is a method of fabricating such a lead.
