    摘要： An implantable electrical lead having a lead body with a longitudinal lumen therein and a stranded electrical conductor located in the lumen and which exits the lumen at a distal portion of the lead body, the distal end of the conductor being curved to form a loop and reentering the lumen, terminating within the lumen alongside a more proximal portion of the conductor. The portion of the conductor exterior to the lumen is wound around the lead body to form a coiled electrode. In some embodiments the distal end of the conductor is coupled to a more proximal portion of the conductor to form a loop and the loop is wound around the lead body to form a bifilar coil. In other embodiments the conductor is wound around the lead body to form a mono-filar coil. The distal end of the conductor is mechanically and electrically coupled to a more proximal portion of the conductor, within the lumen.

    摘要： An introducer or guide catheter for directing an implantable medical device such as a lead or catheter to a desired location within a patient's body. In one embodiment of the invention, the introducer comprises a two-lumen tube. A first lumen is configured to receive the implantable medical device that is to be introduced. A second lumen is provided to receive an insertable, elongated guiding member such as a stylet, which may be shapable in various orientations, and which may be used to alter the configuration of the introducer. The second lumen may be provided with an internal coil or other tubular reinforcement member to prevent perforation of this lumen by the guiding member when the introducer is in the patient's body. In order to facilitate removal of the introducer over an implantable medical device having a connector or fitting that is larger than the internal diameter of the first lumen, the introducer may be adapted to be slit or split along its length. In some embodiments of the invention, the introducer may be rendered splittable by provision of a weakened zone along its length. According to yet another aspect of the invention, the introducer may be provided with a luer lock at its proximal end to facilitate connection of the introducer to a hemostasis valve, t-fitting, or the like.

    摘要： An introducer is structured with an elongated tube having first and second lumens. A molded handle is coupled to the proximal end of the tube with an opening aligned with the first lumen. Further, a wall adjacent the opening of the handle defines a slot and is located diametrically opposite the second lumen. A tubular reinforcement member is located within the second lumen and the handle is provided with a second opening, thereby having a communication with the second lumen. In another embodiment a lead/catheter introducer includes an implantable lead or catheter having an elongated first lumen through which the lead or catheter passes and a second lumen extends parallel to the first lumen along at least a distal portion thereof. A tubular reinforcement member is disposed within the second lumen. The tubular reinforcement member further includes an internal lumen and a curvable stylet disposed in the lumen.

    摘要： A method of removing chronically implanted pacing leads and leads specifically adapted to be removed using the method. The leads are constructed so that upon tension applied to the electrode, it is withdrawn to a first location, so that upon further application of tension, the sheath located distal to the withdrawn electrode may collapse, enhancing its removability. In some embodiments of leads particularly adapted for use in conjunction with the method, the leads are provided with a mechanism for allowing breakage of the lead adjacent the points to which the electrode has been withdrawn, upon application of further tension to the electrode.

    摘要翻译： 使用该方法去除长期植入的起搏引线和引线的方法，其特别适于被去除。 引线被构造成使得当施加到电极的张力时，其被拉出到第一位置，使得在进一步施加张力时，位于引出电极的远侧的护套可能会塌陷，从而增强其可移除性。 在特别适合于与该方法一起使用的引线的一些实施例中，引线设置有用于在向电极施加进一步的张力时允许引线邻近电极已被取出的点断裂的机构。
