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.
