Abstract
A delivery system assembly includes an outer tube, an inner member, extending within a lumen of the outer tube, and a deflectable shaft, extending within the outer tube lumen and around the inner member; the tube and inner member are longitudinally moveable with respect to the shaft, and a distal end of the inner member is located distal to the shaft within the tube lumen. A medical device can be loaded into the tube lumen, along a distal-most portion of the tube, and contained between the inner member and a distal opening of the tube lumen. Deflecting the shaft orients the distal-most portion for navigation of the assembly, and, when the distal end of the inner member is engaged within the tube lumen, distal movement of the tube, with respect to the shaft, causes similar distal movement of the inner member and the loaded medical device toward an implant site.
