Abstract Details

, Master of Sciences (Engineering), Case Western Reserve University, EECS - Electrical Engineering.
Atrial fibrillation (Afib), the most common type of cardiac arrhythmia, affects an estimated 2.7-6.1 million people in the United States and often leads to hospitalization, stroke, sudden cardiac death, and heart failure. Of the available treatments for Afib, catheter ablations are the most effective with success rates of around 75%. Inter-operator variability associated with operator experience influences success rates. Current standard practices use x-ray fluoroscopy imaging to guide the procedure. This imaging technique exposes the patient and medical personnel to harmful radiation and has limitations in image quality. The implementation of a real-time MRI-guided robotic-assisted catheter ablation system can eliminate radiation exposure, provide superior guidance, reduce inter-operator variability, and could result in increased success rates in the treatment of Afib. Such a system is being developed at the Case Western Reserve University Medical Robotics and Computer Integrated Surgery (CWRU MeRCIS) laboratory. This thesis discusses the development of the electronics, software, and mechanical designs of the insertion mechanism for the main catheter and transseptal needle for this system. The system has been designed and tested for safe and reliable operation in an MRI environment, and in-vitro testing of the mechanism to puncture the fossa ovalis into the left atrium has been completed. This project and the results associated, show a proof of concept for the design and operation of the insertion mechanism of a real-time MRI-guided robotic-assisted cardiac ablation catheter system.
