Claim Text:
1. A recovery catheter for collapsing and retrieving a filter device mounted on a distal portion of a guide wire, the recovery catheter comprising: a flexible housing portion adapted to collapse and maintain the filter device in a collapsed position on the guide wire, the flexible housing having a distal end and a proximal end; a flexible intermediate section having a distal end and a proximal end, the distal end of the intermediate section being fixedly attached to the proximal end of the housing portion; and a proximal section fixedly attached to the proximal end of the intermediate section, the proximal section having a locking mechanism which receives and engages a portion of the guide wire, the locking mechanism allowing the housing portion, intermediate portion and proximal section to slide distally along the guide wire in only one direction of motion, the locking mechanism engaging the guide wire to prevent the housing portion, intermediate section and proximal section from moving proximally along the guide wire, wherein the housing portion and intermediate section are adapted to be inserted into a body vessel and the guide wire includes a proximal portion that extends proximally from the proximal section when engaged therein.
