Magnetic and robotic navigation for catheter ablation
Journal of Interventional Cardiac Electrophysiology, 2008Catheter ablation has become the treatment of choice to cure various arrhythmias in the last decades. The newest advancement of this general concept is made on the navigation ability using remote-controlled ablation catheters. This review summarizes the concept of the two currently available systems, followed by a critical review of the published ...

Factors Influencing Contact Force in Robotic Magnetic Navigation Ablation
Journal of Cardiovascular ElectrophysiologyABSTRACT Introduction Stability of catheter‐tissue contact in the robotic magnetic navigation (RMN) system is one of the key features that distinguishes this system from manually guided catheters. Numerous studies have shown that contact force (CF) in manually controlled catheters is as crucial

IEEE Transactions on Industrial Electronics, 2017
We propose a novel magnetic navigation system (MNS) with the resonant effect of an RLC circuit to generate large magnetic field in high frequency. The variable capacitors of the proposed MNS make it possible not only to change the resonant frequency of the RLC circuit, but also to maximize the output current without phase delay at variable resonant

Magnetic controlled navigation system for endoscopic micro robot
2009 IEEE 3rd International Conference on Nano/Molecular Medicine and Engineering, 2009A novel magnetic controlled navigation system is proposed for controlling endoscopic micro robot's locomotion and location in the gastrointestinal tract. The proposed approach exploits permanent magnet and mechanical movement to generate quasi-static magnetic field instead of AC alternating magnetic field, and thus can be applied to the noninvasive ...

Navigation Using an Environmental Magnetic Field for Outdoor Autonomous Mobile Robots
Advanced Robotics, 2011GPS and laser range finders are generally utilized in current robot navigation. However, information from the magnetic field and electronic compass is not, since it is dynamically changing at every position. In this paper, the relationship between the intensity of a magnetic field in the environment and its position is taken into account by utilizing a
