Abstract
Methods and devices for delivering and/or retrieving a filter fixed to a guidewire disposed within a blood vessel are disclosed. A system in accordance with the present invention comprises, an outer shaft having a proximal end, distal end and a wall defining an outer shaft lumen. The system also includes a stop mechanism disposed within the outer shaft lumen. The stop mechanism is preferably configured such that relative axial movement between the guidewire and the outer shaft may be selectively precluded.

29. An assembly, comprising:
-
an outer shaft having a proximal portion, a distal portion, and a longitudinally collapsible portion disposed between the proximal and distal portions, the outer shaft defining an outer shaft lumen, the longitudinally collapsible portion moveable between an extended configuration and a collapsed configuration;
a guidewire disposed within the outer shaft lumen, the guidewire including a filter fixed to the guidewire; and
guidewire gripping means positioned within tie outer shaft lumen and coupled to the outer shaft, the guidewire gripping means reversibly moveable between a relaxed configuration in which the guidewire may move freely in a longitudinal direction and a constricted configuration in which the guidewire is constrained from movement in a longitudinal direction;
wherein the guidewire extends through the guidewire gripping means. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
