摘要： An extendable guidewire system for introducing a dilatation catheter into the cardiovascular system. The guidewire has guidewire and extension sections with a connection therebetween which permits the two sections to be joined together and separated simply by pushing the two sections together and pulling them apart. One of the sections can be used for positioning the catheter within the cardiovascular system, and the other section can be employed to extend the wire to change catheters.

摘要： A steerable balloon dilatation catheter which is particularly suitable for peripheral arteries having an elongated tubular member with a flexible, inelastic balloon on the distal end. The tubular member has a relatively stiff proximal portion formed of stainless steel and a relatively flexible distal portion formed of a polyester. A fixed guiding member is disposed within the catheter bonded to the proximal portion of the tubular member, to a short relatively rigid cylindrical member bonded to the distal portion of the tubular member and the distal end of the balloon.

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.

摘要： The invention is directed to a very low-profile dilatation catheter having an inner tubular member with an inner lumen with a diameter of not more than 0.003 inch (0.076 mm) greater than the diameter of a guidewire disposed therein. 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： 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.
摘要翻译：本发明旨在提供用于起搏和除颤引线的复合引线体设计。该引线体设计提高了植入患者锁骨区域的引导段中的抗前列压抗性，同时在植入心脏的引线段中保持良好的抗疲劳性。锁骨节段具有大致平坦的轮廓。通过使靠近静脉进入部位的锁骨段变平，引线将具有较低的轮廓。此外，通过使锁骨段内的导体基本上共同对准，铅的抗压强度显着提高。

摘要： A method for electrically attaching electrode wire to a conductor in a defibrillation lead is disclosed. The method comprises melting the end of the wire with a hydrogen torch to form a ball of metal, then crimping or welding the ball to the conductor or to a joining piece attached to the conductor. Also, a hydrogen torch (water welder) may be used to join two or more electrode wires to each other.
