Concept, realization, and first in vitro testing of an intraarterial microaxial blood pump with an integrated drive unit.
The intraaortically located micoraxial pump represents a promising device for temporary cardiac assistance in terms of efficiency and practicability. Due to well-documented problems arising from the concept of a pump unit being driven by an extracorporeally placed motor via a flexible drive shaft cable, a new pump concept is presented. The cable is replaced by a proximally attached microelectric motor that needs only an extracorporeal power supply.
