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.
