Summary
A new telerobotic system enables remote navigation of conventional catheters, protecting interventionalists from radiation. This system allows for safe and effective remote catheter navigation and ablation delivery using existing skills.
Area of Science:
- Medical Robotics
- Interventional Cardiology
Background:
- Remote catheter navigation systems reduce radiation exposure for interventionalists.
- Existing systems often necessitate specialized catheters and extensive operator training.
Purpose of the Study:
- To introduce and evaluate a novel compact, sterilizable telerobotic system for remote catheter navigation.
- To assess the system's ability to utilize conventional tip-steerable catheters and leverage existing operator skills.
Main Methods:
- Development of a compact and sterilizable telerobotic system with three degrees of freedom.
- Interface designed to utilize interventionalists' existing dexterity.
- Performance evaluation through ex vivo and in vivo testing for navigation and ablation delivery.
Main Results:
- Achieved high precision with absolute errors of 0.1 ± 0.1 mm (axial motion) and 7 ± 6° (rotation).
- In vivo experiments confirmed the system's safety.
- Demonstrated feasibility of remote navigation and successful ablation delivery.
Conclusions:
- The telerobotic system allows interventionalists to remotely navigate conventional steerable catheters.
- Enables safe distance from radiation sources during catheter navigation and ablation procedures.
