Abstract:
Various coiled conductors having two or more sections and methods and devices for constructing such conductors are disclosed. The various embodiments of coiled conductors and related methods include two or more sections that can have different mechanical, structural, and/or electrical characteristics.
Abstract:
A temporary implantable medical device lead includes a connector configured to connect the lead to an external control module. A helically coiled conductor (40) includes a proximal end that is mechanically and electrically connected to the connector. The conductor includes a plurality of insulated (44a, 44b, 44c, 44d) filars (42a, 42b, 42c, 42d). An insulative layer is removed from an uninsulated portion of each of the filars near a distal end of the conductor. The uninsulated portion of each of the filars is exposed at an outer surface of the conductor such that the exposed uninsulated portions of the filars define a plurality of electrodes (46, 48) at longitudinally spaced sections near the distal end of the conductor.
Abstract:
A medical device lead includes a flexible body having a proximal region with a proximal end, and a distal region with a distal end. A connector is coupled to the proximal end of the flexible body of the lead to electrically and mechanically connect the lead to an implantable pulse generator. The medical device lead also includes an electrode in the distal region of the flexible body, and a cable conductor having a proximal end electrically coupled to the connector and a distal end electrically coupled to the electrode. The cable conductor consists of a single helically coiled filar including a plurality of co-radial turns and having an outer diameter of less than about 0.020 inch (0.508 mm).
Abstract:
A feedthrough assembly is disposable in an aperture of, for example, a power source encasement. In various examples, the feedthrough assembly comprises one or more of a ferrule, an insulator, a terminal conductor, and a sleeve. In various examples, a portion of the terminal conductor extends through the ferrule thereby creating a portion internal to and a portion external to the encasement. The insulator is disposed within the ferrule and is sealably engaged with the terminal conductor portion extending through the ferrule. The sleeve is disposed over the internal portion of the terminal conductor and coupled thereto. In one example, the sleeve includes at least one notch, which may be used to weld or solder the sleeve to the terminal conductor. In another example, the sleeve includes a longitudinally extending void, which may be used to crimp the sleeve to the terminal conductor.
