摘要：
A catheter blood pump includes a cannula with an expandable central portion having a proximal end, a distal end and a blood flow conduit therebetween. A flexible inlet portion at the distal end is provided with a plurality of spaced apart inlet struts configured to prevent an obstruction from entering, and a flexible outlet portion is provided with a plurality of spaced apart outlet struts operative to reduce a swirl velocity of blood, wherein the plurality of spaced apart inlet struts and the plurality of spaced apart outlet struts are fabricated from a collapsible shape memory material.
