An embolic filtering system includes a guide wire, a filter device disposed on the guide wire, a sheath adapted to maintain the filter device in an unexpanded position and a torque device having a lumen for receiving the guide wire and a locking mechanism for locking the torque device to the guide wire. The torque device may include a side port adapted to receive the proximal end of the sheath to allow a portion of the guide wire to shear the sheath from the guide wire through retraction of the sheath through the side port. The torque device may include an extension arm having a distal opening adapted to receive both the guide wire and the sheath. A second lumen may be used to allow a portion of the guide wire to shear the sheath away from the guide wire through retraction of the sheath through the second lumen.

Embolic filtering devices

A locking component for locking a medical device onto a guide wire. Such medical devices include, for example, an embolic filter assembly used to capture embolic material that may be created and released into a patient's vasculature during a stenting or angioplasty procedure. The embolic filter assembly tracks along the guide wire, and is delivered to a treatment site where it is locked in place and deployed. The locking component enables the filter assembly to lock onto any standard guide wire, and does not require a modified guide wire that has a specially-designed fitting or stop to accomplish the locking function.
