A separate deliverable embolic protection device filter that attaches to a helical coil at a distal end of a conventional guide, for use in a blood vessel when an interventional procedure is being performed to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filter assembly with a proximal end and a distal end, and a guide wire connector attached to the distal end of the filter assembly. The guide wire connector is able to couple with the helical coil of the guide wire. A restraining sheath placed over the filter assembly in a coaxial arrangement maintains the filter assembly in a collapsed position and delivers the filter assembly separately to the helical coil of the guide wire, and then the guide wire connector is joined to the helical coil. Alternatively, the guide wire can include a rotatable coil section forming a portion of the distal tip coil on the guide wire which is adapted to be coupled to the filter assembly. This arrangement allows the filter assembly to be rotatably mounted onto the guide wire.
What is claimed is: 1. A method of capturing embolic debris released into a blood vessel of a patient, comprising: inserting a guide wire having a coil at a distal end into the blood vessel and directing the distal end of the guide wire to a treatment area; slidably mounting a filter assembly havin
What is claimed is: 1. A method of capturing embolic debris released into a blood vessel of a patient, comprising: inserting a guide wire having a coil at a distal end into the blood vessel and directing the distal end of the guide wire to a treatment area; slidably mounting a filter assembly having a guide wire connector disposed at one end onto the guide wire, and directing the filter assembly along the guide wire, wherein the guidewire connector includes a spring-loaded tab; and forcing the filter assembly and spring-loaded tab together with the coil of the guide wire, catching the spring-loaded tab in between windings of the coil of the guide wire. 2. The method of claim 1, further comprising placing a sheath over the filter assembly to maintain the filter assembly in a collapsed position, and then directing the sheath including the filter assembly over the guide wire until the connector abuts the coil of the guide wire. 3. The method of claim 2, further comprising retracting the sheath to expose the filter assembly after the connector is coupled to the coil of the guide wire, allowing the filter assembly to form an expanded position. 4. The method of claim 3, further comprising fitting the sheath over the filter assembly and removing the guide wire and sheath from the vessel. 5. The method of claim 1, wherein the guide wire connector is disposed at a distal end of the filter assembly. 6. The method of claim 1, wherein the guide wire connector is disposed at a proximal end of the filter assembly.
