Abstract
A blood pump comprises a pump section and a flow cannula. A proximal end portion of the flow cannula is connected to the pump section such that blood can enter the blood flow inlet, and a distal end portion of the flow cannula includes at least one blood flow-through opening for blood to enter the flow cannula. The distal end portion comprises an enlarged diameter portion, with at least a major portion of the blood flow-through opening being disposed in the enlarged diameter portion. The blood pump further comprises a sleeve overlapping the enlarged diameter portion. The sleeve has a structure that prevents its distal end from bending radially inwards into the blood flow-through openings.
