摘要： An embolic protection device has a collapsible filter element (105) mounted on a carrier such as a guidewire (101). The filter element (105) collapses into the outer end of a catheter (118) for deployment and retrieval through a vascular system of a patient. The filter element (105) has a collapsible filter body with a proximal inlet end and a distal outlet end. The proximal inlet end has inlet openings sized to allow blood and embolic material enter the filter body. The outlet end has outlet openings which allow through passage of blood but retain embolic material within the filter body. After use, the catheter (118) is movable along the guidewire (101) to engage the proximal end of the filter element and close the inlet openings before sliding over the filter element from the proximal end to the distal end to progressively collapse the filter body on the guidewire (101) for retrieval. The filter element (105) may conveniently be mounted on a tubular sleeve (104) which is slidable and rotatable on the guidewire (101) between spaced-apart stops (106, 120) on the guidewire (101) which allows some manipulation of the guidewire independently of the filter when the filter is in use.

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 medical catheter for the transvascular deployment of a collapsaible medial device such as a filter has a tubular body formed by an inner tubular core surrounded by an outer thin-walled tube which is fixed to the core. The outer thin-walled tube extends outwardly beyond a distal end of the core to form a fixed thin-walled medical device embracing pod. The filter is carried on a guidewire which is slidably engagable within a central lumen of the core and the filter can be collapsed against the guidewire for loading within the pod. With the filter thus loaded within the pod the distal end of the catheter can be maneuvered through a patient's vascular system to a desired deployment site where the filter is discharged from the pod allowing the filter to expand within the blood vessel for use filtering blood flowing through the blood vessel.
