Area of Science:

  • Medical Robotics
  • Minimally Invasive Surgery
  • Cardiovascular Interventions

Background:

  • Current endovascular procedures use catheters with limited dexterity for complex intracardiac navigation.
  • The beating heart environment poses unique challenges for interventional tool maneuverability and force application.

Purpose of the Study:

  • To develop and evaluate a millimeter-scale soft robotic platform for enhanced intracardiac intervention.
  • To improve the dexterity, stability, and force application of catheter-based tools within the heart.

Main Methods:

  • Demonstration of a deployable and self-stabilizing soft robotic platform.
  • Testing the platform's ability to guide interventional tools in two exemplar intracardiac procedures within the right atrium.

Main Results:

  • The robotic platform achieved high dexterity, reaching multiple anatomical targets in the right atrium.
  • The platform demonstrated stability for maintaining contact with motile targets.
  • It generated newton-level forces, providing significant mechanical leverage.

Conclusions:

  • The soft robotic platform addresses key challenges in minimally invasive intracardiac interventions.
  • This technology has the potential to advance the development of novel catheter-based treatments for cardiac conditions.
