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; and
coupling an elastomeric material to the at least one helical elongate element, such that the at least one helical elongate element with the elastomeric material coupled thereto defines a blade of the impeller, the coupling being performed such that a layer of the material is disposed around a radially outer edge of the at least one helical elongate element, the layer of material forming the effective edge of the impeller blade;
the method comprising performing a step to enhance bonding of the elastomeric material to the at least one helical elongate element in a manner that does not cause a protrusion from the effective edge of the impeller blade.
