1. A system for locking a component along a guide wire, comprising:
- a guide wire having a flexible body member disposed thereon;
a locking component having a body member including means for temporarily compressing at least a portion of the flexible body member of the guide wire to allow the compressed portion of the flexible body member to be placed in a recess formed in the body member, the compressed portion of the flexible body member being adapted to decompress within the recess to lock the formerly compressed portion of the flexible body member within the recess; and
a medical device which is deliverable over the guide wire and coupled to the locking component, wherein the flexible body member disposed on the guide wire is a coil spring.

Abstract
A locking component delivers and locks an attached medical device along a pre-deployed guide wire. The locking component can lock onto a flexible body member disposed on the guide wire, such as the distal helical tip coil of a conventional guide or a specially-designed guide wire. The locking component includes a tapered opening which temporarily compresses a portion of the helical coil and a locking recess in communication with the tapered opening for receiving the compressed coil. Compressed coils which enter the locking recess will spring back to their original shape (diameter) within the locking recess, locking the component to the coil.

14. A system for locking a component along a guide wire, comprising:
-
a guide wire having a flexible body member disposed thereon; a locking component having a body member including means for temporarily compressing at least a portion of the flexible body member of the guide wire to allow the compressed portion of the flexible body member to be placed in a recess formed in the body member, the compressed portion of the flexible body member being adapted to decompress within the recess to lock the formerly compressed portion of the flexible body member within the recess, the means for temporarily compressing the flexible body member of the guide wire being a longitudinal opening extending into the body member which is adapted to receive and temporarily compress at least a portion of the flexible body member, the recess formed in the locking device being adjacent to the smaller diameter of the longitudinal opening and in communication with the longitudinal opening, the longitudinal opening extending into the body member being proximally tapered from one diameter to a smaller diameter; and a medical device which is deliverable over the guide wire and coupled to the locking component, wherein the flexible body member of the guide wire is a helical coil disposed on the guide wire and the smallest diameter of the tapered, longitudinal opening is smaller than the diameter of the helical coil. - View Dependent Claims (15)

16. An embolic protection device, comprising:
-
a guide wire including a flexible body member fixedly attached thereon; a filter assembly having a proximal end and a distal end; and a guide wire locking component attached to one of the ends of the filter assembly, the guide wire locking component being movable along the guide wire and including means for temporarily compressing at least a portion of the flexible body member of the guide wire to allow the compressed portion of the flexible body member to placed in a recess formed in the guide wire locking component, the compressed portion of the flexible body member being adapted to decompress within the recess to lock the formerly compressed portion of the flexible body member within the recess. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
