A fuzzy controller was developed for the Helmholtz total artificial heart (TAH) to adapt pump rate to body perfusion demand. Initial in vitro tests demonstrate the feasibility and advantages of this control concept for artificial heart systems.

Area of Science:

  • Biomedical Engineering
  • Artificial Organs
  • Control Systems

Background:

  • The Helmholtz total artificial heart (TAH) project began in 1990, focusing on anatomical fitting, biocompatibility, and automatic physiologic adaptation.
  • Key requirements for TAH systems include seamless integration with the body and responsive output adjustment.
  • A labtype TAH was created to evaluate these critical features through in vitro testing.

Purpose of the Study:

  • To develop and evaluate a fuzzy controller for automatic adaptation of the TAH pump rate.
  • To assess the controller's ability to match pump output to physiological demand based on left pump chamber filling.
  • To demonstrate the feasibility and benefits of fuzzy logic control in TAH systems.

Main Methods:

  • Implementation of a fuzzy controller using a professional development tool for real-time optimization.

Related Experiment Videos

  • Utilizing a TAH labtype for in vitro testing of energy conversion, pump dynamics, and control strategies.
  • Left pump chamber filling detection to inform pump rate adjustments for physiological demand.

    • Main Results:

    • The fuzzy controller successfully adapted the pump rate to meet simulated body perfusion demands.
    • Initial in vitro experiments confirmed the feasibility of the fuzzy control concept for the Helmholtz-TAH.
    • The study presented preliminary in vitro test results highlighting the advantages of this control approach.

    Conclusions:

    • Fuzzy control is a viable and advantageous strategy for regulating the pump rate of the Helmholtz-TAH.
    • The developed controller represents a significant step towards a comprehensive TAH control system.
    • Further development and testing are warranted to integrate this controller into future artificial heart systems.
