摘要：
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.
