Embolic protection system
First Claim
1. An embolic protection device comprising:
- a collapsible filter element for delivery through a vascular system of a patient;
the filter element comprising a collapsible filter body and a collapsible filter support frame contacting the filter body;
the filter body having 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 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 being movable between a collapsed position for movement through the vascular system and an extended outwardly projecting position to support the filter body in an expanded position;
the filter support frame having an intermediate section to urge the filter body in the expanded position into apposition with a vessel wall, and a proximal section extending radially inwardly of the intermediate section;
wherein the filter body comprises linking webs between adjacent inlet openings,the proximal section of the filter support frame comprises a first frame element having a section that extends proximally, radially inwardly in alignment with a first linking web, and a second frame element having a section that extends proximally, radially inwardly in alignment with a second linking web, andthe number of inlet openings is two and the number of linking webs is two.

Abstract
An embolic protection system 1 comprises a guidewire 99 for advancing through a vasculature, the guidewire 99 having a distal end and a proximal end; an embolic protection filter 1 having a filter body 41 with a distal end and a proximal end, the filter body 41 providing for a collapsed configuration and an expanded deployed configuration. The embolic protection filter body 41 has a guidewire path for slidably receiving the guidewire 99 to permit movement of the filter 1 relative to the guidewire 99 when the filter 1 is in the collapsed configuration and the expanded deployed configuration. A delivery catheter 2 is advanceable over the guidewire 99 for delivery of the embolic protection filter 1; the delivery catheter 2 having a proximal end and a distal end. The filter 1 is deployed from the distal end of the delivery catheter 2 into the expanded deployed configuration. A retrieval catheter 3 is also advancable over the guidewire 99 for retrieval of the filter 1, the retrieval catheter 3 having a distal end and a proximal end; and engagement elements for engaging the embolic protection filter 1 with the guidewire 99 for retrieval of the filter 1 into the retrieval catheter 3 in the collapsed configuration.
