    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： An embolic protection system having a guidewire for advancing through a vasculature; an embolic protection filter having a filter body with a distal end and a proximal end, the filter body providing for a collapsed configuration and an expanded deployed configuration. The embolic protection filter body has a guidewire path for slidably receiving the guidewire to permit movement of the filter relative to the guidewire when the filter 1 is in the collapsed configuration and the expanded deployed configuration. A delivery catheter is advanceable over the guidewire for delivery of the embolic protection filter. A retrieval catheter is also advancable over the guidewire for retrieval of the filter, and engagement elements are used for engaging the embolic protection filter with the guidewire for retrieval of the filter into the retrieval catheter in the collapsed configuration.

    摘要： A collapsible filter element (40) for a transcatheter embolic protection device (1). The filter element (40) comprises a collapsible filter body (41) 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 filter element (40). A proximal inlet portion of the filter body (41) has two inlet openings (50) sized to allow blood and embolic material enter the filter body (41), and a distal outlet portion of the filter body (41) has a plurality of small outlet openings (51) to allow through-passage of blood, but to retain embolic material within the filter body (41). The filter body (41) is of an oriented polymeric material.

    摘要： A medical guidewire assembly comprises a guidewire having a flexible tip. A medical device such as a collapsible filter for use as an embolic protection device is mounted on the guidewire. The filter is advanced through a body lumen with the guidewire tip extending distally. A variable thickness guidewire (having a recess or thinner segment between thicker segments) can be employed. At a first location the filter is advanced relative to the tip to a location which is distally advanced from the first location. Placement of the filter in an optimal distal location is thereby achieved.
