Abstract: A shield located within an implantable medical lead may be terminated in various ways at a metal connector. The shield may be terminated by various joints including butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. The shield may terminate with a physical and electrical connection to a single metal connector. The shield may terminate with a physical and electrical connection by passing between an overlapping pair of inner and outer metal connectors. The metal connectors may include features such as teeth or threads that penetrate the insulation layers of the lead. The shield may terminate with a physical and electrical connection by exiting a jacket of a lead adjacent to a metal connector and lapping onto the metal connector.

Abstract: A shield located within an implantable medical lead may be terminated in various ways. The shield may be terminated by butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. For lap joints, a portion of an outer insulation layer may be removed and a replacement outer insulation layer is positioned in place of the removed outer insulation layer, where the replacement layer extends beyond an inner insulation layer and the shield. The replacement layer may also lap onto a portion of the insulation extension. The barbs may be located between the replacement layer and the inner insulation layer or the insulation extension. The shield wires have ends at the termination point that may be folded over individually or may be capped with a ring located within one of the insulation layers of the jacket.

Abstract: A tool for deploying an anchor sleeve onto an implantable device includes handle and base members, which may be fitted together by an operator. The operator may select the handle member from a plurality thereof included in a kit; and the base member, also included in the kit, includes a rail segment with which a gripping portion of the selected handle member may be engaged, for example, via guidance from a marked portion of the base member. Once engaged, a deployment tip of the base member is located to move a mounted anchor sleeve from a tubular member of the handle member and onto a body of the device. The tubular member of some tools has a laterally offset distal end portion, on which the corresponding anchor sleeve is mounted; thus, kits including this type of handle member, may include a converter for the base member to facilitate engagement therewith.

Abstract: Anchors for use with implantable medical leads include an elastic body containing one or more rigid bodies that have longitudinal free edges. The longitudinal free edges run from end to end to define full length slots. Partial length slots may also be included within the one or more rigid bodies. The full length and partial length slots allow for deflection of the rigid bodies against the body of an implantable medical lead to hold the anchor in place on the lead. The full length slots allow a blade to pass through and cut a slit in the elastic body which allows the anchor to be removed from the lead.

Abstract: A system for monitoring an approach to a target includes a luminal device including a distal portion, a sensor coupled to the distal portion of the luminal device, and a surgical instrument including one or more indicators having a detectable property located along at least a portion of the surgical instrument. The luminal device is configured to be inserted into a patient, and the distal portion of the luminal device is configured to be guided proximate a target. The sensor is configured to sense the detectable property of the one or more indicators. The surgical instrument is configured to be guided through the luminal device.

Abstract: Implantable medical leads and implantable lead extensions include a shield. The implantable medical lead is coupled to the implantable lead extension. Stimulation electrodes of the implantable medical lead contact stimulation connectors within a housing of the implantable extension to establish a conductive pathway for stimulation signals from filars of the implantable extension to filars of the implantable medical lead. Continuity is established between the shield of the implantable medical lead and the implantable extension by providing a radio frequency conductive pathway within the housing. The radio frequency conductive pathway extends from a shield of the implantable extension to a shield connector that contacts a shield electrode of the implantable medical lead. The radio frequency conductive pathway may have various forms such as a jumper wire or an extension of the shield within the implantable extension.

Abstract: Radiopaque markers represent that a lead is suitable for a particular medical procedure such as a magnetic resonance image scan and are added to the lead or related device. The markers may be added after implantation of the lead in various ways including suturing, gluing, crimping, or clamping a radiopaque tag to the lead or to the device. The markers may be added by placing a radiopaque coil about the lead, and the radiopaque coil may radially contract against the lead to obtain a fixed position. The markers may be added by placing a polymer structure onto the lead where the polymer structure includes a radiopaque marker within it. The polymer structure may include a cylindrical aperture that contracts against the lead to fix the position of the polymer structure. The polymer structure may form a lead anchor that includes suture wings that can be sutured to the lead.

Abstract: A needle biopsy system includes an elongated shaft and a needle shaft. The elongated shaft includes a proximal portion, an intermediate portion more flexible than the proximal portion, and a distal portion that is less flexible than the intermediate portion. The needle shaft has a distal tip configured to cut and receive a sample of tissue and is longitudinally movable through the elongated shaft between a first position and a second position. In the first position, the distal tip of the needle shaft is disposed within the elongated shaft, and in the second position, the distal tip of the needle shaft extends distally from the distal portion of the elongated shaft to cut and receive a sample of tissue.

Abstract: Medical leads include a lumen body at an end of the lead, and the lumen body includes multiple filar lumens. The lumen body is joined to a lead body, and electrical connectors are longitudinally spaced along the lumen body. Filars within the filar lumens are directed through filar passageways within the lumen body to attach to the electrical connectors on the lumen body. The filar passageways may be aligned with the filar lumens, and slots within the electrical connectors may be aligned with the filar passageways to facilitate assembly. The lumen body may provide additional stiffness to the end of the lead where the lumen body is located to facilitate lead insertion into the medical device. The filar lumens of the lumen body may have a longitudinally straight configuration so that the portions of filars within the filar lumens are held in a longitudinally straight configuration.
