摘要： An impeller includes a hub (10), and a plurality of blades (12) supported by the hub, the blades being arranged in at least .two blade rows. The impeller has a deployed configuration in which the blades extend away from the hub, and a stored configuration in which at least one of the blades is radially compressed, for example by folding the blade towards the hub. The impeller may also have an operational configuration in which at least some of the blades are deformed from the deployed configuration upon rotation of the impeller when in the deployed configuration. The outer edge of one or more blades may have a winglet (122), and the base of the blades may have an associated indentation to facilitate folding of the blades.
