    摘要: A method of assembling an apparatus for delivering an implant to a deployment site in a patient's vasculature, includes: positioning an implant engagement member at least partially within a lumen of a tubular structure, the tubular structure having a sidewall comprising a pattern of wires or struts; heating the implant engagement member; pressing at least a portion of the sidewall of the tubular structure radially inward into a surface of the implant engagement member so that the wires or the struts of the sidewall penetrate into the surface and create corresponding recesses therein; and after the recesses are created in the surface of the implant engagement member, hardening the implant engagement member.

    摘要: The system includes a control handle portion and a catheter portion coupled to the control handle portion at a proximal end of the catheter portion. The catheter portion includes an outer shaft. The outer shaft includes a plurality of segments arranged in an axial direction to form the outer shaft the catheter portion, each of the plurality of segments being configured to move relative to one another. The system also includes a distal portion coupled to a distal end of the outer shaft, the distal portion being configured to receive the implantable medical device.
