Abstract: Seals used within lead bores of implantable medical devices for creating a seal to implantable medical leads inserted into the lead bores include an inner cylinder that engages the lead body. The inner cylinder is surrounded by a gap to either an outer cylinder of the seal or to surrounding structures of the implantable medical device. The inner cylinder has freedom of movement within the gap such that movement of the lead body that is off-axis relative to a centerline of the lead bore causes movement of the inner cylinder that is providing the seal. In this manner, the seal engagement to the lead body is maintained during this off-axis movement of the lead body.

Abstract: A connector assembly, for example, employed in an extension of an implantable medical electrical system, may be contained in a flexible insulative sleeve so that a bore thereof extends along a longitudinal axis of the sleeve with an opening being formed by a distal terminal end of the sleeve. The assembly includes a plurality of isolation ring components interspersed among a plurality of contact ring components, wherein each of a plurality of conductor components has a first end coupled to a corresponding contact ring component, and a curvature formed along a length thereof, which length extends proximally from the coupled first end and into a proximal portion of the sleeve. To facilitate routing of the conductor component lengths, either each isolation ring component may include at least one guide, or a flexible inner insulative sleeve of the assembly may have longitudinally extending channels formed in an outer surface thereof.

Abstract: An insulative body of a medical electrical lead electrode assembly includes a pre-formed channel having a section extending at an angle to a longitudinal axis of the body. An electrode portion of a conductive component has an electrode contact surface facing outward from a first side of the body and a coupling portion embedded in the body. A conductor, which is coupled to the coupling portion of the component, is disposed in the channel.

Abstract: An epidural space is cleared of fat and scar tissue in preparation for implantation of a medical lead by utilizing a clearing tool. The clearing tool has a flexible body that allows the clearing tool to deflect when entering the epidural space through a window in the vertebral bone and ligaments. The clearing tool is guided into the epidural space and to a target site by a guidewire present in the epidural space. Upon removal of the guidewire and clearing tool, the medical lead is inserted through the window and cleared epidural space until reaching the target site. The clearing tool may include a distal tip with a shape and size that aids in the clearing of the epidural space. The distal tip may be integral to the clearing tool or may be removable so as to allow for different sizes of the distal tip to be installed as needed.

Abstract: An epidural space is cleared of fat and scar tissue in preparation for implantation of a medical lead by utilizing a clearing tool. The clearing tool has an outer body and an inner body present within a lumen of the outer body. The outer body may be malleable and have a pre-set deflection or may be flexible and achieve deflection when being inserted into the epidural space. Once in the epidural space, the inner body is extended distally from the lumen of the outer body such that a distal tip on the inner body extends further into the epidural space to provide clearing to the target site without requiring further ingress of the outer body. The inner body is retracted and the clearing tool is removed. The medical lead is then inserted through the window and cleared epidural space until reaching the target site.
Abstract translation: 通过利用清除工具，可以将硬膜外腔清除脂肪和瘢痕组织，以准备植入医用铅。 清除工具具有外体和存在于外体的内腔内的内体。 外体可以是可延展的并且具有预设的偏转或者可以是柔性的，并且当插入硬膜外腔时实现偏转。 一旦在硬膜外腔中，内体从外体的内腔向远端延伸，使得内体上的远侧末端进一步延伸进入硬膜外腔，以便在不需要进一步进入外体的情况下向目标部位提供清除。 内体缩回，并清除清理工具。 然后将医疗用铅插入窗户并清除硬膜外腔，直到达到目标部位。

Abstract: A medical lead includes a lead body, an electrical connector, an electrical conductor, and a sleeve. The lead body includes a distal end and a proximal end defining a longitudinal axis of the lead body. The electrical connector is positioned near the proximal end of the lead body. The electrical conductor extends about the longitudinal axis of the lead body. The sleeve is coupled to an insulative material of the lead body and positioned around the electrical conductor. The electrical conductor is electrically coupled to the electrical connector. The sleeve is not fixed to the electrical conductor. In response to bending of the medical lead, the conductor may move within the sleeve to relieve strain created by the bending.

Abstract: Implantable medical leads and/or lead extensions include a band that encapsulates a portion of conductors of the lead and/or lead extension. The band may be reflowed in order to provide the encapsulation of the conductors. The band may further be used to create a seal together with the surrounding lead body and an additional object such as a stiffener rod, stylet tube, and/or molding stylet, to allow a proximal area of a lumen of the lead body to be injection molded while prevent the injection molding material from proceeding past the band. When a stiffener rod is present in a proximal area of the lead and/or lead extension, additional stiffness is provided to the lead body to resist buckling of the lead body during insertion of the proximal end. The band may be bonded to the stiffener rod to fix the position of the stiffener rod relative to the conductors.
