Abstract
A lead insulator which provides resistance to tearing and/or abrasion for implantable flexible electrical lead insulators having a body of silicone elastomer material. A relatively thin layer of a second silicone is applied as an overcoat to a more substantial primary or first insulator body. The second silicone is more resistant to tearing and/or abrasion than the elastomer comprising the body of the insulator. Because tearing and/or abrasion are surface phenomena, only a relatively thin layer of the second material is particularly required and the mechanical properties of the primary material will determine the overall mechanical properties of the lead insulatior per se.
