1. A system for enabling the capture of embolic material which may be released into a blood vessel during a therapeutic interventional procedure, comprising:

  • a guide wire, including a distal end, adapted to be positioned within the blood vessel and to extend to a position distal to an interventional procedure site, the guide wire including a proximal stop and a distal stop, adapted to be secured to the distal end of the guide wire, and having a space between the proximal stop and the distal stop; and

    a filter device, adapted to be positioned and deployed at a location in the patient'"'"'s vasculature distal to the interventional procedure site, and to capture embolic material which may be released into the blood in the blood vessel during the interventional procedure, including an engaging element, for enabling the filter device to be snap-fitted so as to engage the distal end of the guide wire;

    wherein the engaging element of the filter device includes a snap-fitting component and is adapted to enable snap-fitting engagement within the space formed between the proximal stop and distal stop.
