1. A method, comprising:
manufacturing an impeller by:
forming a structure having first and second bushings at proximal and distal ends of the structure, the first and second bushings being connected to one another by at least one elongate element;
causing the at least one elongate element to radially expand and form at least one helical elongate element, at least partially by axially compressing the structure;
coating the at least one helical elongate element with a coupling agent, the coupling agent configured to enhance bonding between the helical elongate element and an elastomeric layer;
subsequently, coating the coupling-agent-coated helical elongate element with the elastomeric layer; and
subsequently, coupling an elastomeric film to the at least one helical elongate element, such that the at least one helical elongate element with the elastomeric film coupled thereto defines a blade of the impeller.
