Abstract:
1. In combination a device for delivering a stent within an intraluminal cavity and a stent comprising: a guidewire having a proximal end and a distal end; a stent mounted on and carded by the guidewire, the stent movable between a smaller diameter delivery position and an expanded placement position, and having a proximal portion an intermediate portion and a distal portion; a tubular portion fixedly attached to the distal portion of the guidewire, the guidewire and the attached tubular portion advanceable together intraluminally to deliver the stent to a surgical site; and at least two arms extending from the tubular portion and extending in a distal direction, the arms encircling portion of the guidewire when the tubular portion is attached to the guidewire, the arms advanceable together with the guidewire to the surgical site and the guidewire extending between the arms, the arms movable to pivot between an initial closed stent constraining position to retain the stent for delivery and a subsequent open stent release position to place the stent at the surgical site, each arm engages the proximal portion and the distal portion of the stent to surround the stent and constrain the stent on the guidewire in the initial closed stent constraining position for delivery of the stent to the surgical site, the arms having free ends movable toward and away from each other between the closed position to constrain the stent and to the subsequent open stent release position to release the stent from the guidewire for expansion and placement at the surgical site.
