Stent delivery device
First Claim
1. A stent delivery device comprising:
- a guide member having a proximal end and a distal end;
a stent mounted to said guide member, wherein the stent is spaced proximally from the distal end of the guide member;
a segmented restraining sleeve disposed about the stent, the restraining sleeve having a first end, a second end, and a plurality of segments, each segment extending from the first end to the second end; and
an actuating member which cooperates with the first end and second end of the restraining sleeve to maintain said first and second ends in close proximity thereby applying a restraining force to at least a portion of said stent to prevent said stent from expanding, said restraining sleeve cooperatively engaged with the actuating member, so that movement of said actuating member in a proximal direction releases said restraining force to deploy said stent.

Abstract
A stent delivery device comprises a guide member having a proximal end and a distal end, and a stent mounted to the guide member. A restraining member positioned about the stent comprises two or more portions that are held together by one or more actuating members. The one or more actuating members can be positioned by a user in a proximal direction, since the one or more actuating members extend to the proximal end, or handle, of the guide member. When a user moves the one or more actuating members in a proximal direction, the one or more actuating members slide away from the two or more portions, allowing the stent to expand. The stent delivery device can further be configured to include an embolic protection component.

6. A stent delivery device comprising:
-
a guide member having a lumen, a proximal end, and a distal end; a stent mounted to said guide member, wherein the stent is spaced proximally from the distal end of the guide member; a segmented restraining sleeve disposed about the stent, the restraining sleeve including a first end, a second end, and a plurality of circumferentially-oriented segments; and an actuating member disposed within the lumen which cooperates with the first end and second end of the restraining sleeve to maintain said first and second ends in close proximity thereby applying a restraining force to at least a portion of said stent to prevent said stent from expanding, said restraining sleeve cooperating with the actuating member such that movement of said actuating member in a proximal direction releases said restraining force to deploy said stent. - View Dependent Claims (7, 8)
