Modeling Electromagnetic Navigation Systems for Medical Applications using Random Forests and Artificial Neural Networks

Ruoxi Yu, Samuel L. Charreyron, Quentin Boehler, Cameron Weibel, Christophe Chautems, Carmen C. Y. Poon +1
ICRA 2020poster

Electromagnetic Navigation Systems (eMNS) can be used to control a variety of multiscale devices within the human body for remote surgery. Accurate modeling of the magnetic fields generated by the electromagnets of an eMNS is crucial for the precise control of these devices. Existing methods assume…

Design and Evaluation of a Steerable Magnetic Sheath for Cardiac Ablations

Christophe Chautems, Sean Lyttle, Quentin Boehler, Bradley J. Nelson
RA-L 2018

Precise catheter control is crucial to the success of radiofrequency cardiac arrhythmia ablations. Remote control using external magnetic fields to directly steer the catheter tip is a promising strategy to accurately and easily perform cardiac catheter steering. Magnetic catheters must be flexible

A variable stiffness catheter controlled with an external magnetic field

Christophe Chautems, Alice Tonazzini, Dario Floreano, Bradley J. Nelson
IROS 2017poster

Remote magnetic navigation of catheters is a technique used to perform radiofrequency ablation of heart tissue in order to treat cardiac arrhythmias. The flexible magnetic catheters used in this context are in some cases not sufficiently dexterous to navigate the complex and patient-specific anatomy…
