Patent ID: 7169172

Claim:
In combination a device for delivering a stent within an intraluminal cavity and a stunt comprising: a tubular portion, having a proximal end, a distal end and a lumen therethrough; a stent having a length having a midpoint and a proximal portion proximal of the midpoint of the stent and an opposing distal portion distal of the midpoint of the stent, the stent movable between a smaller diameter delivery position and an expanded placement position; at least two arms attached to the distal end of the tubular portion, the arms configured to form a cage in an area between the arms for constraining a the stent therein, the arms having a proximal section and a distal section defined along their length to constrain the respective proximal portion and distal portion of the stent, the arms extending beyond the midpoint of the stent to constrain the stent, the arms having free ends movable toward and away from each other between an open and closed position, the arms normally in a closed position to provide a closed cage to constrain the stent, the arms being urged against their normal closed position to the open position wherein the free ends of the arms are spaced a greater distance apart than in the closed position to open the cage to release the stent from the cage for movement of the stent to the expanded placement position,; a mechanism for controllably moving the arms radially a distance from one another to move the arms between the normally closed position and the open position. an outer sheath, wherein the outer sheath constrains the stent and retraction of the sheath enables the stent to expand; and a hook extending from the arms to engage the sheath to retract the sheath proximally.
