Abstract
A lead has a flexible lead body which extends from a proximal end to a distal end. The lead body has a conductor coupled with an electrode. At least a portion of the flexible lead body includes a polymer of vinylidene fluoride, or a polymer of vinylidene fluoride and silicone rubber. The polymer of vinylidene fluoride includes, but is not limited to, a homopolymer, a copolymer, or a terpolymer.
Claims18
A lead assembly comprising:
- a flexible lead body extending from a proximal end to a distal end, the lead body including at least one conductor disposed therein, at least a portion of the flexible lead body comprising a polymer of vinylidene fluoride and a layer of silicone rubber, and where the polymer of vinylidene fluoride comprises an outer layer of insulation;
- and
- an electrode assembly including at least one electrode electrically coupled with the conductor.
A lead assembly comprising:
- a flexible lead body extending from a proximal end to a distal end, the lead body including at least one conductor disposed therein, at least a portion of the flexible lead body comprising a polymer of vinylidene fluoride that is mounted over an outside surface of another portion of the flexible lead body comprising silicone rubber;
- and
- an electrode assembly including at least one electrode electrically coupled with the conductor.
A lead assembly comprising:
- a flexible lead body extending from a proximal end to a distal end, the lead body including at least one conductor disposed therein;
- at least a portion of the flexible lead body comprising a polymer of vinylidene fluoride, and at least a portion of the flexible lead body comprising silicone rubber, wherein the vinylidene fluoride comprises a first layer of insulation, and the silicone rubber comprising a second layer of insulation that is covered by the first layer of insulation;
- and
- an electrode assembly including at least one electrode electrically coupled with the conductor.
1 more element
A method comprising:
- increasing the abrasion resistance of a lead assembly having a flexible lead body and at least one electrode, including applying a layer of silicone rubber onto the flexible lead body and applying a layer of a polymer of vinylidene fluoride onto the layer of silicone rubber.
