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: Shielded sheaths are placed over implantable medical leads and/or implantable medical lead extensions to provide shielding from electromagnetic energy and to prevent heating at the electrodes. The shielded sheaths include insulative bodies with shield layers such as conductive braided wire or conductive foil tubular structures. The shielded sheath may be implanted at the time of implanting the lead and/or lead extension. The shielded sheath may also be implanted at a later time after the lead and/or lead extension has previously been implanted. The shielded sheath may be anchored onto the lead or lead extension.

Abstract: An introducer assembly that may be employed to implant a medical device includes an introducer shaft, and an anchor sleeve and a deployment tool mounted on the shaft. According to some methods, the sleeve is deployed onto an elongate body of the medical device, after the body has been advanced through a lumen of the introducer shaft and to an implant site within a body of a patient, by pulling the introducer shaft proximally, out from the body of the patient, while holding the deployment tool in place, relative to the advanced body of the device.

Abstract: Dislodging an anchor sleeve from an implanted device may be accomplished with a tool that includes a support portion and a sleeve dislodging element, wherein a collar of the support portion engages a distal end of the anchor sleeve while the dislodging element, positioned at a proximal end of the sleeve, is moved toward the collar to dislodge the anchor sleeve. The tool preferably includes a handle member held in sliding engagement with a base member, for example, by a snap-fit, wherein the support portion is part of the handle member, and a distal segment of the base member is terminated by the dislodging element. A tool kit may include a plurality of base members, each one including a different type of dislodging element, from which an operator may select for snap-fitting to a handle member of the kit.
