AI Technical Summary
Current ventricular assist devices face challenges in efficiently manufacturing impellers that maintain blood flow and prevent radial expansion, which can lead to inefficiencies and potential hemolysis during cardiac support.
The method involves forming an impeller with proximal and distal bushings connected by elongate elements, coating these elements with a coupling agent and an elastomeric layer, and incorporating an impeller-overexpansion-prevention element to prevent radial expansion, ensuring efficient blood pumping and minimizing hemolysis.
This solution enhances the efficiency of blood pumping by maintaining a consistent gap between the impeller blades and the inner surface, reducing hemolysis and improving cardiac support by maintaining a stable blood flow rate.
