8. A method of manufacturing an embolic protection filter, comprising the steps of:
-
providing an embolic protection filter manufacturing assembly, the assembly including a base member, a shaft extending from the base member, a first arm coupled to the shaft and including a mandrel member, and a second arm coupled to the shaft and including a filter material holding member;
coupling a filter material to the filter material holding member;
bringing the mandrel member into contact with the filter material such that the filter material stretches to define a stretched filter-shaped member;
disassociating the mandrel member from the filter-shaped member;
coupling the filter-shaped member to a stretch frame;
disposing the filter-shaped member and stretch frame adjacent a drilling apparatus;
drilling a plurality of holes in the filter-shaped member with the drilling apparatus; and
annealing the filter-shaped member. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
