Method and assembly for distal embolic protection
First Claim
1. A distal embolic protection assembly adapted to be introduced through the apex of the heart of a patient, the assembly comprising:
- a sleeve having a lumen;
an actuating member having proximal and distal ends, wherein the actuating member is movably disposed within the lumen of the sleeve; and
a filter assembly coupled to the distal end of the actuating member, the filter assembly comprising a porous bag having an open proximal end and a collapsible and expandable frame coupled to the open proximal end;
wherein the actuating member may be pulled in a proximal direction to compress and retract the frame within the lumen of the sleeve and retain the frame in a collapsed state and wherein the actuating member may be pushed in a distal direction out of the lumen to a deployed expanded state.

Abstract
Methods and assemblies are described for capturing embolic material in a blood vessel or other body cavity during cardiovascular or valve replacement and repair surgery, wherein access is provided through the apical area of the patient'"'"'s heart. The distal embolic protection assembly generally comprises a sleeve having a lumen, an actuating member having proximal and distal ends, wherein the actuating member is movably disposed within the lumen, and a filter assembly coupled to the distal end of the actuating member. The filter assembly generally comprises a porous bag having an open proximal end, a collapsible and expandable frame that is coupled to the open proximal end of the porous bag, and at least one support spine disposed at least a part of the longitudinal axis of the porous bag. The porous bag is configured such that it permits blood to perfuse freely through while capturing embolic material and other debris.
