    摘要: An implantable defibrillator lead comprises a flexible core onto which is wound helically wound coils to form an electrode. These electrode coils are partially encapsulated by a flexible matrix which holds them in their wrapped position around the core. Due to its coiled coil structure, this electrode provides improved flexibility, and can be used endocardially, intravascularly, epicardially, or subcutaneously. The electrode may function alternately as a defibrillation electrode and as a sensing electrode in a lead with a separate pacing electrode.

    摘要: The present invention is directed toward providing a composite lead body design for pacing and defibrillation leads. This lead body design improves the lead crush resistance in the lead segment that is implanted in the patient's clavicular region, while maintaining good fatigue resistance in the lead segment implanted in the heart. The clavicular segment has a generally flat profile. By flattening the clavicular segment proximal to the venous entry site, the lead will have a lower profile. Also, by substantially co-aligning the conductors within the clavicular segment, the crush resistance of the lead is significantly improved.

    摘要: An implantable lead conductor comprises at least one helical coil formed from at least one electrical cable. Each cable is formed from several wires twisted in a ropelike configuration with at least some of the wires being helically wound around a central axis of the cable. Each wire is a composite comprising a core of a first material and a coveting of a second material, with all adjacent wires belonging to the same cable in uninsulated contact with each other. Preferably, the core material is highly conductive, and the covering material is strong and biocompatible. The helical coil has a lumen for insertion of a stylet to facilitate insertion through a vein.

    摘要: An implantable defibrillator lead comprises a flexible, conductive lead member having proximal and distal end portions. The distal end portion defines a plurality of separate, curvilinear electrodes which naturally extend laterally outwardly in a curved arrangement from the remainder of the lead. However, by desired means, the curvilinear electrodes may be temporarily extended out straight, substantially parallel to the axis of the remainder of said lead member, to facilitate implantation of the lead. This may be preferably accomplished by a flexible sheath that encloses the lead member in longitudinally slidable relation.

Preferably, the inner diameter of the tubular member is less than 0.015 inch (0.381 mm). The inner member may be formed of a thin-walled tubing such as polyimide tubing having a wall thickness less than 0.003 inch (0.076 mm). Polyimide tubing is also preferably employed as the tubular member in low-profile steerable dilatation catheters wherein the guide elements thereof are fixed within the catheter.

    摘要: Low profile dilatation catheter having an elongate flexible tubular member with proximal and distal extremities and with a flow passage extending therethrough. An inflatable balloon is mounted on the distal extremity of the elongate flexible tubular member so that the balloon has its interior in communication with the flow passage in the tubular member. A flexible tip is secured to the distal extremity of the balloon. A core wire extends through the elongate flexible member and has proximal and distal extremities. The distal extremity of the core wire is tapered and extends through the balloon and into the flexible tip. The distal extremity of the core wire is secured to the flexible tip. A rotator is provided for rotating the proximal extremity of the core wire for causing rotation of the flexible tip. Self-venting means is provided for venting the balloon to ambient. An adapter is carried by the proximal extremity of the elongate tubular member. A liquid is supplied to the adapter and the flow passage for inflating and deflating the inflatable balloon.
