DOUBLE LUMEN AORTIC CANNULA AND CROSS CLAMP ASSEMBLY AND RELATED METHODS

摘要

Cardiothoracic surgical devices with a dual lumen cannula (8) that cooperates with a clamping assembly (35) for facilitating a CPB. The dual lumen cannula (8) has a distal end portion (8d) configured to reside inside an aorta (A) of a patient. The distal end portion (8d) has a first lumen (9) and a second lumen (10) in fluid isolation. The first lumen (9) has a lumen orifice (13) that faces a first direction inside the aorta and the second lumen (10) comprises a lumen orifice (15) that faces a second direction that is different than the first direction inside the aorta. The clamp assembly (35) is coupled to the dual lumen cannula (8) and configured with first and second clamp arms (1351, 1352) that are configured to align with the distal end portion (8d) of the dual lumen cannula (8) and clamp against opposing external surfaces of a vessel wall of the aorta to compress the vessel wall against the distal end portion (8d) of the dual lumen cannula (8) and thereby provide first and second fluidly isolated segments of the aorta.
