Patent ID: 8579915

Claim:
A method for removing an obstruction from a cerebral vessel, comprising the steps of: providing an obstruction removing device having an elongate element, the elongate element being movable from a collapsed position to an expanded position and being naturally biased toward the expanded position, the elongate element having a proximal section, a distal section and an intermediate section, the intermediate section being positioned between the distal and proximal sections, at least one of the proximal and distal sections forming at least two loops having a longitudinal axis, the intermediate section having a first crossing portion which intersects the longitudinal axis and a second crossing portion which also intersects the longitudinal axis, the at least two loops forming a circle when viewed along the longitudinal axis, the first and second crossing sections extending diametrically across the circle when viewed along the longitudinal axis; introducing the obstruction removing device into a patient with the elongate element being in the collapsed position; expanding the elongate element after the introducing step; engaging an obstruction with the elongate element; and removing the obstruction with the elongate element.
