Stent delivery system
First Claim
1. A stent delivery system, which comprises:
- a handle defining a channel;
an elongate catheter extending from the handle, the elongate catheter defining a leading end and a trailing end, and having a longitudinal axis, the elongate catheter including;
an inner member;
an outer member mounted about the inner member and adapted for longitudinal movement relative to the inner member from an extended position to a retracted position; and
a stent mounted about the inner member;
a thumbwheel mounted to the handle and connected to the outer member, the thumbwheel adapted for rotational movement to cause corresponding movement of the outer member from the extended position to the retracted position; and
a clip connected to the outer member and comprising a lock wall, wherein the clip includes an anti-rotation wing configured to be received within the channel and to traverse the channel in response to rotation of the thumbwheel;
a lock member releasably mountable to the handle and including a clip restraint configured to engage with the lock wall of the clip distal to a proximal end of the anti-rotation wing, wherein the lock member is adapted to engage the thumbwheel to prevent movement thereof when the lock member is secured relative to the handle, and adapted to release the thumbwheel when the lock member is released relative to the handle.

Abstract
A stent delivery system includes a handle and an elongate catheter extending from the handle, and defining a leading end and a trailing end, and having a longitudinal axis. The elongate catheter includes an inner member, an outer member mounted about the inner member and adapted for longitudinal movement relative to the inner member from an extended position to a retracted position and a stent mounted about the inner member. The stent delivery system also includes a thumbwheel mounted to the handle and operatively connected to the outer member, and a lock member releasably mountable to the handle. The thumbwheel is adapted for rotational movement to cause corresponding movement of the outer member from the extended position to the retracted position. The lock member is adapted to engage at least one of the outer member and the thumbwheel to prevent movement thereof when the lock member is secured relative to the handle, and is adapted to release the at least one of the outer member and the thumbwheel when the lock member is released relative to the handle. The lock member may be adapted to engage each of the outer member and the thumbwheel to prevent respective movement thereof when the lock member is secured relative to the handle and adapted to release each of the outer member and the thumbwheel when the lock member is released relative to the handle.

18. A stent delivery system comprising:
-
a handle; a catheter extending from the handle, the catheter including; an inner member; an outer member mounted about the inner member and adapted for longitudinal movement relative to the inner member from an extended position to a retracted position; and a stent mounted about the inner member; a hub; a thumbwheel rotatably mounted to the handle via the hub, the thumbwheel including a radial surface defining a plurality of radial recesses, wherein each radial recess of the plurality of radial recesses is defined by a closed boundary, is spaced from an adjacent radial recess of the plurality of radial recesses, and is separated from the adjacent radial recess by the radial surface, the thumbwheel being connected to the outer member and adapted for rotational movement to cause corresponding movement of the outer member from the extended position to the retracted position; and a lock member releasably mountable to the handle and including a lock detent, wherein the lock detent is adapted to engage a radial recess of the plurality of radial recesses of the thumbwheel to prevent movement of the thumbwheel when the lock member is secured relative to the handle. - View Dependent Claims (19, 20, 21)
