  • LEAD HAVING VARYING STIFFNESS AND METHOD OF MANUFACTURING THEREOF
    Publication number: 20070239249
    Abstract: An apparatus includes a lead body extending from a proximal end to a distal end and having an intermediate portion therebetween. The lead body includes two or more individually insulated conductors, where a first conductor traverses along less than an entire length of the lead body and a second conductor traverses from the proximal end to the distal end of the lead body. Optionally, the first conductor has a different material than the second conductor, for instance having differing electrical properties and/or differing stiffnesses. A method includes varying the stiffness of a coiled conductor assembly including winding a plurality of conductors to form the coiled conductor assembly, and pulling at least one loop of a first conductor away from the coiled conductor assembly.

  • Endocardial lead with vinylidene fluoride insulation
    Patent number: 6477428
    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.
