1. A system for manipulating a filter fixed to a guidewire disposed within a blood vessel, comprising:
- an outer shaft having a proximal end, distal end and a wall defining a shaft lumen;
A an proximal guidewire port extending through the wall of the outer shaft for allowing the guidewire to pass through the wall so that it is partially disposed within the shaft lumen; and
a stop mechanism coupled to the outer shaft distally of the proximal guidewire port, said stop mechanism adapted to engage the guidewire.

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.

10. A system for manipulating a filter fixed to a guidewire disposed within a blood vessel, comprising:
-
an outer shaft having a proximal end, distal end and a wall defining a shaft lumen;
a stop mechanism comprising a stop member fixed to the outer shaft and a stop fixed to the guidewire;
the stop member defining an aperture having a inner radial extent and further comprising a set of jaws; and
the stop having an outer radial extent that is generally greater than the inner radial extent of the aperture defined by the stop member.

12. A system for manipulating a filter fixed to a guidewire disposed within a blood vessel, comprising:
-
an outer shaft having a proximal end, distal end and a wall defining a shaft lumen;
an inner shaft slidingly disposed within the shaft lumen;
a gripper fixed to the outer shaft; and
wherein the gripper has a first, undeflected shape, and a second, deflected shape for grasping the guidewire. - View Dependent Claims (13, 14, 15, 16)

-
an outer shaft having a proximal end, distal end and a will defining a shaft lumen;
an inner shaft slidingly disposed within the shaft lumen;
a gripper fixed to the inner shaft; and
wherein the gripper is configured such that relative axial movement between the inner shaft and the outer shaft causes the gripper to grasp the guidewire. - View Dependent Claims (18, 19, 20)
