    摘要： A method and apparatus for caged stent delivery is provided herein. The device can be used to position and deliver any type of stent to a preselected treatment site within an intraluminal cavity. The device comprises a tubular portion, a plurality of arms attached to the distal end of the tubular portion, and a mechanism to open the arms. In operation, the caged device carries a stent in a constricted form to the treatment site for deployment. The arms of the cage are then opened, the stent released and deployed, and the device withdrawn. Several methods are provided to open the arms, including various pullwires, a piston, an electrolytic joint, and an activator. The arms may be constructed of a shape memory alloy and opened when shape memory behavior is effected. The device may be used with conventional catheters or used with a stent-loaded guidewire.

    摘要： A guidewire loaded stent for delivery through a catheter is described herein. The stent delivery assembly can deliver and place a stent within tortuous regions of the body which are accessible to guidewires but inaccessible to stenting catheters. The assembly comprises a guidewire covered in part by a retractable sheath and a radially expandable stent near or at the distal end of the guidewire. The whole assembly is advanced through conventional catheters or it may be used alone. In either case, when the stent is adjacent to a treatment site within the body, the sheath is retracted proximally to expose the stent for radial expansion into contact with the vessel wall. Radio-opaque marker bands are optionally located on either side or both sides of the stent on the guidewire body to aid in visual placement. The assembly can optionally include an expandable balloon on the guidewire for different treatment modalities.

    摘要： A stent delivery system comprising a hypotube, a guidewire extending beyond a distal end of the hypotube and having a first portion and a second portion. The first portion has a second diameter less than the diameter of the hypotube. The second portion of the guidewire has a third diameter less than the second diameter and forming a reduced diameter portion for receiving a stent. A sheath covers at least a portion of the reduced diameter portion of the guidewire.
