A new intrathoracic artificial heart pump offers wireless power and remote control, eliminating percutaneous lines. This electrohydraulic device, functioning as a ventricular assist device or total artificial heart, enhances patient mobility and quality of life.

Area of Science:

  • Biomedical Engineering
  • Cardiovascular Devices
  • Implantable Technology

Background:

  • Percutaneous connections in existing artificial heart systems pose infection risks and limit mobility.
  • The need for reliable, long-term circulatory support devices is critical for patients with end-stage heart failure.

Purpose of the Study:

  • To develop and evaluate an intrathoracic pulsatile artificial heart pump with transcutaneous energy transfer and biotelemetry.
  • To assess the device's potential as both a ventricular assist device and a total artificial heart.
  • To enhance patient quality of life through wireless power and remote monitoring capabilities.

Main Methods:

  • Development of an electrohydraulic system utilizing a unidirectional axial flow pump and a pressure-activated one-way valve.

Related Experiment Videos

  • Integration of a transcutaneous energy transfer system for continuous power and battery recharging.
  • Implementation of a biotelemetry system for remote monitoring and control, coupled with a wearable external controller.

    • Main Results:

    • Prototypes demonstrated failure-free operation for up to 3 years in vitro.
    • The device successfully sustained circulation in vivo for up to 4 days in initial studies.
    • The system design allows for enhanced patient mobility and remote device management.

    Conclusions:

    • The developed intrathoracic artificial heart pump shows promise for wireless, remotely managed circulatory support.
    • The absence of percutaneous connections significantly reduces infection risk and improves patient quality of life.
    • Further chronic in vivo evaluation and design optimization are warranted to advance this technology.
