20080262592 | INTRALUMINARY STENT RELOCATING APPARATUS - An apparatus for moving an object disposed within a body lumen. The apparatus includes a first sheath, a coupling member and at least one contraction member for engaging at least a portion of the object. The coupling member is movable relative to the first sheath between a retracted position and a capture position. In the retracted position, a distal portion of the coupling member is disposed within the first sheath. In the capture position, the coupling member distal portion is disposed outside the first sheath. The coupling member is also selectively attachable to the object in at least the capture position. When the coupling member is attached to the object and the contraction member is directly engaged with the object, a predetermined coupling member movement relative to the contraction member radially contracts at least a portion of the object thereby facilitating movement of the object within the body lumen. | 10-23-2008 |
