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.

摘要： A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and an interference fit member for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft by an interference fit between the interference fit member and the drainage stent such that axial movement of the elongate shaft relative to the drainage stent moves the interference fit member from a first position in which the interference fit member is engaged with the drainage stent and forms an interference fit with the drainage stent to a second position in which the interference fit member is disengaged from the drainage stent.

摘要： An open frame prosthesis is formed with looped end terminations at its proximal and distal ends. At one end of the prosthesis, the filaments or strands are welded together in pairs to form strand couplings. A plurality of loop segments are connected to the strand couplings, one loop segment for each pair of adjacent strand couplings. In one version of the prosthesis, strands at the opposite end are bent to form looped ends. In another version, loop segments are connected to pairs of strand couplings at both ends of the prosthesis. The loop segments can be connected to the couplings by welding, fusion bonds, or tubes, which are either crimped or heat shrunk.

摘要： A drainage stent delivery system including a stent, a guide catheter, a push catheter, and an outer sheath. The guide catheter extends through the lumen of the stent and the push catheter is disposed over a portion of the guide catheter proximal of the distal end of the stent. The outer sheath is slidably disposed over the push catheter and surrounding at least a portion of the stent. The outer sheath may be actuated from a first position in which a distal portion of the outer sheath surrounds the stent to a second position in which the distal portion of the outer sheath is proximal of the stent. The stent delivery system may also include a retention mechanism for selectively coupling the stent to the outer sheath which may selectively decouple the stent from the outer sheath through rotational and/or translational motion of the outer sheath relative to the stent.

摘要： A method for making an implantable stent includes the steps of (i) providing a plurality of elongate stent wires; (ii) forming said wires into a hollow tubular structure having opposed first and second open ends; (iii) terminating said wires at the second end; (iv) aligning the wires at the second end into a plurality of mated adjacent wires to define a plurality of abutting regions; (v) welding the mated adjacent wires to one and the other at the abutting regions to define a plurality of welds; and optionally (vi) chemically or electro-chemically removing a portion of the welds. The method may further include the steps of (a) extending at least one of the mated stent wires to provide an extended stent wire; (b) looping the extended stent wire so the extended end abuts a proximal pair of stent wires; and (c) welding the extended and looped wire to the proximal pair of wires. The step of looping may include the forming of the wire into a equilaterally arched loop having an apex, but not having other sharp bends.
