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.
