    摘要: Assemblies and methods provide for implantation of multiple medical leads to a defined space within the body, such as the epidural space, through a single entry. A catheter having multiple lumens or alternatively a single oblong lumen may be used. A distal end of the catheter enters the defined space through the single entry such that the distal ends of the multiple lumens or the oblong lumen are present in the defined space. Medical leads are introduced through the multiple lumens or the oblong lumen into the defined space. In some cases, the distal end of the catheter may be deflectable to direct the medical leads within the defined space. In other cases, sheaths may be present within each lumen of the catheter where the sheaths may be extended into the defined space and deflect to direct the medical leads that are being passed through a lumen of the sheaths.

    摘要: An example catheter includes an elongate member having a wall defining a longitudinally extending lumen, a fixation member disposed on an exterior surface of the wall of a distal portion of the elongate member, a pull wire extending axially through the wall of the elongate member and coupled to the fixation member, and a member portion encasing at least a portion of the fixation member, where the fixation member is shaped to engage the distal member in response to a pull force applied to the pull wire to cause the elongate member to deflect from an initial configuration to a deflected configuration.

    摘要: A tubular wall, which may be employed in a medical catheter or medical electrical lead, is formed by stranding together a plurality of polymer fibers and at least one metal filar, wherein the stranding forms a braid matrix of the polymer fibers and a coil of the metal filar interlaced therewith. Then, while the braid matrix secures a pitch of the coil, a polymer material is extruded around an entire length of the tubular wall, and, in some cases, the extrusion process causes the plurality of polymer fibers to melt and coalesce together with one another, while the pitch of the coil is maintained. Alternately, a reflow process, which follows extrusion, causes the polymer fibers to melt and coalesce along all, or just a discrete length of the tubular wall.
