1. A device for pulling a length of wire out of a tube having front and back ends comprising:
- a reel for receiving the length of wire;
a frame to which the reel is mounted, the frame including an abutment for the back end of the tube;
a manually operable slider mounted to the frame for a stroke of backward movement and a stroke of forward movement;
a connectionthat engages the slider and the reel when the slider moves backward, configured to rotate the reel about an axis to wind a portion of the length of wire onto the reelandthat disengages the slider and the reel when the slider moves forward and returns to the start of the backward stroke;
anda detent that restrains the reel from rotation during the forward stroke.

Abstract
A hand-held actuator device for releasing into the body from a delivery system a medical prosthesis, like a stent, comprising a frame (10) that acts as a housing, a reel (30) for receiving a wire (8), a manually operable slider (34) mounted to the frame and a one-way connection between the slider and the reel. Actuating the slider causes the reel to wind up the wire and release the medical prosthesis.

15. A device for pulling a length of wire out of a tube having front and back ends comprising:
-
a reel for receiving the length of wire and means for fixing one end of the wire to the reel; a frame to which the reel is mounted, the frame including an abutment for the back end of the tube; a manually operable slider mounted to the frame for a stroke of backward movement and a stroke of forward movement; a connection that engages the slider and the reel when the slider moves backwards, configured to rotate the reel about an axis to wind a portion of the length of wire onto the reel and and that disengages the slider and the reel when the slider moves forward and returns to the start of the backward stroke; wherein the connection comprises teeth on the slider and co-operating teeth on an element connected to the reel, wherein the teeth on the slider and the teeth on the element engage with each other during the backward stroke and slip over each other during the forward stroke; a detent that restrains the reel from rotation during the forward stroke. - View Dependent Claims (16)

17. A device for pulling a length of wire out of a tube having front and back ends comprising:
-
a reel for receiving the length of wire and means for fixing one end of the wire to the reel; a frame to which the reel is mounted, the frame including an abutment for the back end of the tube; a first hub mounted at the front end of the frame to receive the back end of the tube; a manually operable slider mounted to the frame for a stroke of backward movement and a stroke of forward movement; a connection that engages the slider and the reel when the slider moves backwards, configured to rotate the reel about an axis that winds a portion of the length of wire onto the reel and that disengages the slider and the reel when the slider moves forward and returns to the start of the backward stroke; and a detent that restrains the reel from rotation during the forward stroke. - View Dependent Claims (18)

19. A pull wire system for deploying a trans-luminal, catheter mounted, self-expanding stent by pulling a length of wire out of a tube having front and back ends comprising:
-
a reel for receiving the length of wire and means for fixing one end of the wire to the reel; a frame to which the reel is mounted, the frame including an abutment for the back end of the tube; a manually operable slider mounted to the frame for a stroke of backward movement and a stroke of forward movement; a first hub mounted at the front end of the frame to receive the back end of the tube; a connection that engages the slider and the reel when the slider moves backward to rotate the reel about an axis to wind a portion of the length of wire onto the reel and that disengages the slider and the reel when the slider moves forward and returns to the start of the backward stroke; wherein the connection comprises teeth on the slider and co-operating teeth on a an element connected to the reel, wherein the teeth on the slider and the teeth on the element engage with each other during the backward stroke and slip over each other during the forward stroke; and a detent that restrains the reel from rotation during the forward stroke. - View Dependent Claims (20)
