摘要： An extendable medical lead comprises a lead body and a sheath defining a cavity that encloses a length of the lead body. The length of the lead body enclosed within the sheath may be coiled or otherwise gathered such that when extended, the length of the enclosed section of the lead body is greater than the length of the sheath. The sheath may include a seal to help prevent contaminant entry into the cavity in order to help reduce tissue in growth around the length of the lead body disposed within the sheath. A portion of the length of the lead body enclosed within the sheath exits the cavity through an aperture defined by the seal when a tensile force is applied to the lead body.

摘要： A needle driver is described that can be used to drive a plurality of surgical needles into or proximate to tissue of a living body. The needle driver assists the surgeon in perforating the tissue, creating the tracts at a desired depth, and creating multiple tracts simultaneously. The needle driver is configured to hold the needles securely when creating the tracts, and is also configured to disengage from the needles after the tracts have been created.

摘要： A stimulation electrode array is described. The electrode array can include multiple electrode sets, and can be connected by a single lead to an implantable pulse generator. The implantable pulse generator can drive one set of electrodes to one potential, and another set to a different potential. When implanted in target tissue, the electrodes can stimulate the target tissue while avoiding stimulation of neighboring muscles, organs or nerves.

摘要： A system for implanting a medical electrical lead includes an elongated lead body and a relatively non-compliant lead extension joined to a proximal end of the proximal portion of the lead body. The lead body includes a plurality of connector rings positioned about a proximal portion of the lead body. The lead extension includes a plurality of temporary contact surfaces and a plurality of conductors wherein each conductor joins a temporary contact surface to a corresponding connector ring.

摘要： Apparatus for affixing implantable catheters and leads to body tissue. An electrode located on the lead or catheter is coupled to an RF signal generator, of the type employed to perform electrosurgical procedures such as electrocoagulation. The RF signal causes the electrode to adhere to body tissue, thus stabilizing the location of the catheter or lead. The electrode may be a dedicated electrode employed only for affixation. Contact between the electrode and the RF signal generator may be made by a removable conductor.

摘要： A deflectable tip introducer or guide catheter optimized for placement of leads or catheters within the vasculature of the human body is disclosed. The introducer includes inner and outer concentrically located tubular sheaths. The inner and outer sheaths are preferably provided with different curved configurations, allowing the over-all displayed curvature of the introducer over its distal portion to be adjusted by longitudinal movement of the inner and outer sheaths relative to one another. The outer sheath may be fabricated of a thin tube of polyetheretherketone (PEEK) or other material having a relatively large stiffness as compared to the inner sheath. The outer sheath is sized to fit closely around the inner sheath. The inner sheath may be formed of a reinforced polyurethane, and preferably has a thin wall that is of about .005 inches in thickness or less. When supported by the inner sheath, the outer sheath transfers torque along the composite introducer assembly and serves to modify the curved configuration displayed by the distal end of the introducer assembly in conjunction with the relative longitudinal movement of the inner and outer sheaths.
摘要翻译：公开了一种优化用于将引线或导管放置在人体脉管系统内的可偏转尖端导引器或导引导管。导入器包括内部和外部同心定位的管状护套。内护套和外护套优选地设置有不同的弯曲构型，从而允许通过内护套和外护套相对于彼此的纵向移动来调节导引器在其远端部分上的总体显示曲率。与内护套相比，外护套可以由聚醚醚酮（PEEK）或具有相对较大硬度的其他材料的细管制成。外部护套的尺寸适合紧密围绕内部护套。内护套可以由增强聚氨酯形成，并且优选具有厚度约为0.005英寸或更薄的薄壁。当由内护套支撑时，外护套沿着复合导引器组件传递扭矩并且用于结合内护套和外护套的相对纵向运动来改变由导引器组件的远端显示的弯曲构造。
