    摘要： 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.

    摘要： An implantable lead comprises a lead body extending from a lead proximal end portion to a lead distal end portion. The lead body includes one or more longitudinally extending lumens. A conductor is received in, and extends along, a lumen. In varying examples, the implantable lead further comprises a tubular electrode co-axial with, and overlying portions of, the lead body. In one example, a lumen wall is sized and shaped to urge an electrically conductive interposer coupled with the conductor toward an inner surface of the electrode. In another example, a ring member is disposed within a lumen and the conductor is drawn and coupled thereto. In yet another example, an electrically conductive connector couples a first and a second conductor via grooves or threads. In a further example, an axial support member couples a distal end electrode and the lead body. Methods associated with the foregoing are also discussed.

    摘要： A lead body for use with medical devices and method for lead body manufacture are provided. The lead body defines a lumen. The lumen has an electrically conductive material deposited on the lumen wall. The lead body's manufacture includes coating a lumen wall of a lead body with a conductive material to provide a conductor between the proximal and distal ends of the lead body. The manufacture further includes fitting sleeves electrically connected to electrical elements within the lumen to provide an electrical connection between the sleeve and the conductive material.

    摘要： Novel synthetic pathways to derive aliphatic polyester-grafted polysaccharides from cyclic ester monomers, preferably, poly(.epsilon.-caprolactone) and starch. Different reaction schemes lead to compositions with various levels of grafting. The grafting reactions were conducted using bulk monomer and an organometallic polymerization agent (catalyst or initiator) such as metal alkoxides initiators which were generated in-situ by the reaction of metal alkyls with hydroxyl groups of the polysaccharide. The grafting reactions were characterized by very fast reaction times of the order of a few minutes to effect complete conversion of monomer. Biodegradable compositions, particularly using these poly(.epsilon.-caprolactone)-grafted starch are described for use in film applications.
