摘要： An embolic protection device comprises a collapsible filter element for delivery through a vascular system of a patient. The filter element comprising a collapsible filter body and a filter support frame contacting the filter body. The collapsible filter body has an inlet end and an outlet end, the inlet end of the filter body having one or more inlet openings sized to allow blood and embolic material to enter the filter body, the outlet end of the filter body having a plurality of outlet openings sized to allow through passage of blood but to retain undesired embolic material within the filter body. The filter support frame is movable between a collapsed position for movement through the vascular system and an extended outwardly projecting position to support the filter body in the expanded position. The frame has a plurality of engagement segments which are spaced-apart longitudinally and transversely when the filter body is in the deployed expanded configuration to urge the filter body into opposition with the vessel wall. The engagement segments define at least partially a substantially helical engagement track.

摘要： A collapsible filter element for a transcatheter embolic protection device, the filter element comprises a collapsible filter body of polymeric material which is movable between a collapsed stored position for movement through a vascular system and an expanded position for extension across a blood vessel such that blood passing through the blood vessel is delivered through the filer element. A proximal inlet portion of the filter body has one or more inlet openings sized to allow blood and embolic material enter the filter body. A distal outlet portion of the filter body has a plurality of generally circular outlet openings sized to allow through-passage of blood, but to retain embolic material within the filter body. The distal outlet portion of the filter body in the region of the outlet openings has means for reducing shear stress on blood passing through the outlet openings. The shear stress reducing means includes lead-in and lead-out radiussed portioins of the filter body leading to the outlet holes. The porosity of the distal portion of the filter body decreases towards the distal end. A blind portion extends for at least 5% of the length of the body. Preferably there are between 200 and 300 outlet opening with an average diameter of approximately 150 microns.
