Summary
This study introduces FlyCaD, a robotic catheter system using magnetic torque transmission for sterile manipulation. The prototype shows promise for robotic catheter procedures, despite needing further development for clinical use.
Area of Science:
- Robotics
- Medical Devices
- Biomedical Engineering
Background:
- Sterility management is a critical challenge in robotic catheter manipulation.
- Existing systems often require complex sterilization procedures or compromise sterility.
Purpose of the Study:
- To present FlyCaD, an early-stage robotic catheter-drive prototype.
- To demonstrate contactless magnetic torque transmission across a sterile barrier for robotic catheter manipulation.
Main Methods:
- The FlyCaD system utilizes a reusable base and a disposable cartridge for magnetic coupling.
- Catheter gripping, release, and guidewire rotation are achieved via magnetic interaction.
- Linear motion is performed using a clamp-translate-release-retract sequence.
Main Results:
- The prototype successfully completed all catheter insertion-retraction and guidewire-catheter manipulation cycles.
- 8/10 branch selection trials were successful on the first attempt.
- The system accommodated commercial catheters (4F-8F) and demonstrated easy cartridge exchange.
Conclusions:
- FlyCaD proves the feasibility of contactless magnetic torque transmission for robotic catheter systems.
- The prototype serves as a functional proof of concept, not a clinically validated platform.
- Future work includes characterization, improved actuation, and wireless control.
