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.
