摘要： Bilumen catheters and methods of using same for facilitating implantation of cardiac leads for applying electrical stimulation to and/or sensing electrical activity of the heart through one or more electrode positioned at an implantation site within a heart chamber or cardiac vessel adjacent a heart chamber, and more particularly to a method and apparatus for introducing such a cardiac lead having low torqueability and pushability through a tortuous pathway to enable attachment of the cardiac lead at the implantation site employing a bilumen guide catheter are disclosed. The bilumen catheter body includes a relatively large diameter delivery lumen to introduce a small diameter cardiac lead and a small diameter guide lumen to receive a stylet or guidewire to locate the guide catheter body distal end at the implantation site. The small diameter lumen within a small diameter guide tube extends distally from the delivery exit port of the delivery lumen.

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： 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.
摘要翻译：导引器或引导导管，用于将诸如引线或导管的可植入医疗装置引导到患者体内的期望位置。在本发明的一个实施例中，导引器包括两腔管。第一管腔被配置为接收待引入的可植入医疗装置。提供第二内腔以接收可插入的细长引导构件，例如探针，其可以以各种取向成形，并且其可以用于改变导引器的构造。第二内腔可以设置有内部线圈或其他管状加强构件，以在导引器位于患者体内时防止引导构件对该内腔穿孔。为了便于在具有大于第一内腔的内径的连接器或配件的可植入医疗装置上移除导引器，导引器可以适于沿着其长度被切割或分开。在本发明的一些实施例中，导引器可以通过沿着其长度提供弱化区域而被分解。根据本发明的另一方面，导引器在其近端可以设置有鲁尔锁，以便于将导引器连接到止血阀，t形配件等。

摘要： A medical electrical lead having a fixation helix which is surface treated along at least a portion to have a relatively high microscopic area along with a relatively low macroscopic area. In the preferred embodiment, such a surface treated portion is accomplished with a porous platinized construction. The surface treated portion further has a bioabsorbable coating in order to permit the helix to be inserted into the heart tissue without causing damage to the heart tissue through the engagement of the surface treated portion with heart tissue during insertion. In the preferred embodiment the bioabsorbable material is mannitol, although other bioabsorbable materials may also be used, such as a material which is no more than sparingly soluble in water, for example, the steroid beclomethasone dipropionate anhydrous. Through such a construction the helix may be inserted into tissue while the coating of absorbable materials provides a smooth surface between the surface treated portion of the helix and the tissue. Once inserted, the coating is absorbed and the surface treated portion provides electrical contact with the heart tissue.
摘要翻译：一种具有固定螺旋线的医用电导线，其沿着至少一部分被表面处理以具有相对较高的微观区域以及较低的宏观区域。在优选实施例中，这种表面处理部分是用多孔铂化结构完成的。表面处理部分还具有生物可吸收涂层，以便允许螺旋被插入到心脏组织中，而不会在插入期间通过表面处理部分与心脏组织的接合而引起对心脏组织的损伤。在优选的实施方案中，生物可吸收材料是甘露糖醇，尽管也可以使用其它生物可吸收材料，例如不超过微溶于水的材料，例如无水型类固醇倍氯米松二丙酸酯。通过这样的结构，螺旋可以插入组织中，而可吸收材料的涂层在螺旋的表面处理部分和组织之间提供光滑的表面。一旦插入，涂层被吸收并且表面处理部分提供与心脏组织的电接触。

摘要： A transvenous lead introducer having a mechanical valve assembly disposed thereon. In a preferred embodiment, a longitudinally splittable introducer sheath is provided with a sliding valve at or near one end. The sliding valve may be spring-biased to a normally closed position. A semicircular notch may be provided in the forward end of the sliding valve, so that the sheath may be effectively sealed even when a guide wire runs through the sheath. In an alternative embodiment, the sliding valve is adapted to have its forward end inserted into a notch in the cylindrical sheath body. The mechanical valve assembly is further configured to permit use with a splittable lead introducer sheath.
