Abstract

An embolic protection filter and method of making the same. An embolic protection filter may include a filter membrane or material (16) having a plurality of holes. In some embodiments, the filter membrane may be manufactured by spray coating a filter material onto a forming member or spray mold (26, 126, 226, 426, 626, 826).
