Electromagnetic navigation platform for endovascular surgery: how to develop sensorized catheters and guidewires
Summary
This study introduces an electromagnetic navigation system to guide endovascular procedures, reducing radiation and contrast agent use. The system achieved high accuracy in phantom trials, showing promise for safer interventions.
Area of Science:
- Medical Engineering
- Interventional Radiology
- Surgical Navigation
Background:
- Current endovascular procedures rely on 2D imaging, increasing risks from X-ray exposure and nephrotoxic contrast agents.
- Limitations in current imaging modalities pose challenges for precise endovascular interventions.
Purpose of the Study:
- To develop and evaluate an electromagnetic navigation system for guiding endovascular procedures.
- To reduce radiation dose and the need for contrast medium injection during interventions.
Main Methods:
- Utilized five degrees of freedom (DOF) electromagnetic sensors for real-time tracking of catheters and guidewires.
- Integrated intraoperative 3D rotational angiography for patient anatomy modeling.
- Developed a prototype system and tested its feasibility using an anthropomorphic phantom.
Main Results:
- Achieved a spatial accuracy of 1.2 ± 0.3 mm over 70 targeting trials.
- Demonstrated system usability with positive feedback from three surgeons.
- Validated the feasibility of the electromagnetic navigation prototype in a phantom model.
Conclusions:
- The developed sensorization strategy for endovascular instruments enables surgical approaches with reduced radiation and contrast medium.
- Further validation through in vitro, animal, and clinical studies is required for comprehensive surgical application.
- This technology offers a pathway toward safer and more efficient endovascular interventions.
