Patent ID: 7837703

Claim:
A method of using a guidewire which includes a core wire, a core wire tip disposed at a distal end of the core wire, and a hypo shaft, moveably and coaxially disposed around the core wire, the method comprising: sliding the hypo shaft along the core wire until a distal end of the hypo shaft meets the core wire tip; inserting the hypo shaft into a vasculature and moving the hypo shaft through the vasculature until a proximal end of the core wire tip is downstream of a treatment area; sliding the hypo shaft in a proximal direction from a proximal end thereof to form a filter location space between a distal end of the hypo shaft and the core wire tip; sliding a delivery sheath, containing an embolic protection device therein, coaxially along the hypo shaft until a proximal end of the embolic protection device passes a distal end of the hypo shaft; pulling the delivery sheath from a proximal end thereof to deploy the embolic protection device into the filter location space; and removing the delivery sheath from the vasculature.
