  • Patent number: 9144485
    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.

  • Patent number: 8043450
    Abstract: A method of cutting tissue for use as an implantable medical device employs a laser cutting system. The laser cutting system is computer controlled and includes a laser combined with a motion system. The laser precisely cuts segments out of source tissue according to predetermined pattern as designated by the computer. The cutting energy of the laser is selected so that the cut edges of the tissue segments are fused, melted or welded to discourage delamination or fraying, but communication of thermal energy into the segment beyond the edge is minimized to avoid damaging the tissue adjacent the edge.
