The present invention involves a blood pump having a blood pump and internally disposed rotor, wherein each of the pump housing and rotor are capable of being expanded from a first state of generally reduced dimension to a second state of generally increased dimension. The blood pump may be advantageously introduced into the patient (and onward to the pumping site) while in the first state and thereafter operated (automatically or manually) into the second state for use in pumping blood to augment or replace the pumping capacity of the patient's heart. |
