Abstract:
1. A distal protection device comprising: an elongate core wire; an elongate tubular shaft slidably disposed about the core wire; and a protection element including a braided tubular mesh having a plurality of pores having transverse dimensions, wherein each pore of the mesh is selectively transformable between a filter configuration and an occlusive configuration, the mesh having at least one inlet opening adjacent a mesh proximal end, the mesh being mounted coaxially about the core wire such that a mesh distal end is coupled about a core wire distal end and the mesh proximal end is coupled about a shaft distal end; wherein, relative longitudinal movement between the proximal and distal ends of the mesh end causes transformation of the protection element between a collapsed configuration, the filter configuration wherein each pore of the mesh is substantially open and the occlusive configuration wherein the mesh is longitudinally contracted to reduce the transverse dimensions of the plurality of pores such that each pore of the mesh is substantially closed.
