Abstract

Apparatus and methods are described including an impeller for use in a blood pump. An impeller frame includes proximal and distal end portions and at least one helical elongate element that winds from the proximal end portion to the distal end portion. A material is coupled to the helical elongate element, such that the helical elongate element with the material coupled thereto defines a blade of the impeller. A mediator is coupled to the helical elongate element. The helical elongate element has a first stiffness, the material has a lower stiffness than the first stiffness, and the mediator is configured to enhance bonding between the helical elongate element and the material. Other applications are also described.
