This study introduces a robotic system for semi-automatic, precise catheter navigation within the heart, reducing radiation exposure for interventionalists. The system accurately steers catheter tips to target locations, demonstrating feasibility in preliminary animal studies.
Area of Science:
- Medical Robotics
- Cardiovascular Interventions
- Medical Device Development
Background:
- Manual catheter navigation is imprecise and exposes physicians to radiation.
- Dexterity is required for efficient catheter manipulation.
Purpose of the Study:
- Develop a system for accurate, semi-automatic tele-navigation of intracardiac catheters.
- Replace manual catheter manipulation with robotic assistance.
Main Methods:
- A robotic apparatus was developed based on a catheter distal shaft kinematic model.
- The system automatically steers the catheter tip to designated targets within cardiac chambers.
Main Results:
- Catheter modeling was validated in swine experiments.
- The robotic system achieved a mean targeting accuracy of 6.53 mm.
Conclusions:
- Preliminary in vivo studies show the system's feasibility for catheter navigation.
- Catheter modeling and control strategies are validated.
