Abstract: An inner subassembly of a delivery system assembly extends within a lumen of an elongate outer tube of the assembly, and includes a flared distal end, which is preferably configured to conform to a proximal end of an implantable medical device; a distal-most portion of the outer tube is sized to contain both the flared distal end and an entirety of the medical device. The inner subassembly includes a core, an elongate pull-wire, extending along the core, and a sheath surrounding the pull-wire and the core; the sheath includes a slot opening that allows the pull-wire to pass laterally therethrough. The assembly preferably has a pre-formed curvature along a length of the sheath, and the slot opening extends along the pre-formed curvature. The outer tube is longitudinally moveable relative to the inner subassembly, for example, to deploy the medical device.

Abstract: A delivery system assembly includes an elongate outer tube, an elongate inner member extending within a lumen of the outer tube, and an articulation sheath surrounding the outer tube between a handle of the assembly and a distal-most portion of the outer tube. The outer tube is longitudinally moveable within the sheath; and an inner diameter of the sheath is preferably smaller than that of the handle and the distal-most portion of the outer tube. Navigation of the assembly through a venous system, for deployment of an implantable medical device, is facilitated by deflection of the sheath, to orient a distal-most portion of the outer tube, within which an entirety of the medical device is contained/loaded, and by subsequent advancement of the distal-most portion, with respect to the sheath, to move the distal end of the inner member, along with the contained/loaded device into proximity with a target implant site.
