摘要：
A system for intraluminally delivering and deploying stents and other prostheses includes an outer catheter, an inner catheter movable axially relative to the outer catheter, and an anchoring device mounted to a distal end region of the inner catheter. The anchoring device includes one or more control features that interact with a linking structure proximally disposed on the prosthesis, preferably including one or more loops. The control features and loops interact by surface engagement to anchor the prosthesis relative to the inner catheter in a nonfrictional manner, thus to maintain lower axial prosthesis deployment and retraction forces. In one version of the anchor, the control features extend radially outward from a sleeve. In another version, the control features are formed in respective recesses which also receive the loops or other linking structure.
