Abstract

A delivery device can include a number of different features including, one or more of, but not limited to, the following. Shuttle and trigger retraction of an outer sheath. Arcuate movement of a trigger. An interlock device to prevent actuation of the trigger. An interlock device that can adjust the position of the outer sheath and the inner shaft. A retraction override switch and lock.

First claim

1 .- 14 . (canceled)

15 . A delivery device for deploying a self-expanding medical device within a vessel, the delivery device comprising:
a restraining sheath having a proximal end and a distal end, the restraining sheath being adapted to extend over one or more self-expanding medical devices to maintain the medical devices in a collapsed position and to be retractable to expose the one or more collapsed medical devices for deployment; and a handle housing that includes an arcuate channel and a control mechanism including an actuation assembly coupled to the proximal end of the restraining sheath for retracting the restraining sheath, a slider assembly comprising a trigger positioned within the arcuate channel, the trigger configured to slide within the arcuate channel in an arcuate path of motion from a first extended position to a second position where the trigger is advanced further into the housing as compared to the first extended position, the retraction of the restraining sheath being actuated by an actuating force applied by a user to a movable component of the control mechanism which moves in an arcuate path thereby changing the angle of force application and the mechanical advantage of the force applied by a user depending on the location of the movable component along the arcuate path.

16 . A system for deploying two or more intraluminal devices within a vessel, the system comprising:
two or more intraluminal devices, each comprising at least one radiopaque marker; an inner shaft having a proximal end and a distal end, the distal end having two or more delivery platforms for deployment of the two or more intraluminal devices, each intraluminal device in a collapsed state and located in a separate delivery platform; a restraining sheath having a proximal end and a distal end, the restraining sheath being adapted to extend over the one or more intraluminal devices to maintain the intraluminal devices in a collapsed position and to be retractable to expose the one or more collapsed intraluminal devices for deployment, the restraining sheath further comprising a sheath radiopaque marker in a distal portion of the sheath located at a set distance with respect to the most distal intraluminal device; a control mechanism including an actuation assembly coupled to the proximal end of the restraining sheath for retracting the restraining sheath with respect to the inner shaft, the retraction of the restraining sheath being actuated by an actuating force applied by a user to a movable trigger component of the control mechanism, wherein the trigger is configured such that actuation of the trigger from a starting position to an end position completely withdraws the outer sheath from covering one of the one or more delivery platforms thereby releasing one of the one or more intraluminal devices from the inner shaft into a location within the vessel, and further whereby the sheath radiopaque marker at the distal end of the restraining sheath is located at the set distance with respect to the remaining most distal intraluminal device and the trigger is configured such that a subsequent actuation of the trigger from the starting position to the end position completely withdraws the outer sheath from covering the remaining most distal intraluminal device.

17 . The system of claim 16 , wherein the movable trigger is configured to move in an arcuate path.

18 . The system of claim 16 , the control mechanism further comprising a rack with a plurality of teeth, the rack coupled to the restraining sheath; at least one pawl configured to engage with the plurality of teeth on the rack; and a shuttle configured for selective engagement with the plurality of teeth on the rack.

19 . The system of claim 16 , wherein the sheath radiopaque marker is located a set distance from the distal end of the restraining sheath that is half an overall length of each of the intraluminal devices.

20 . The delivery device of claim 19 , wherein the sheath radiopaque marker is 3 mm from the distal end of the restraining sheath.

21 . The system of claim 16 , wherein each of the two or more intraluminal devices comprises a frame consisting of a single column of cells extending circumferentially.

22 . The system of claim 21 , wherein the at least one radiopaque marker on each of the two or more intraluminal devices comprises a plurality of radiopaque markers positioned in the center of the intraluminal device spaced equidistant around the circumference.

23 . The system of claim 16 , wherein in a first pre-deployment position the radiopaque marker in the distal portion of the sheath is aligned with the at least one radiopaque marker on the most distal intraluminal device.
