Catheter ablation is a common electrophysiological (EP) procedure to treat irregular heart rhythm conditions, such as atrial fibrillation. Catheter ablation can be assisted through the use of imaging coils under magnetic resonance imaging (MRI) which provides a roadmap for preoperative preparation and intraoperative catheter navigation. Intra-cardiac imaging coils allow for ablated lesions to be observed in real time with excellent soft tissue contrast, providing electrophysiologists better control over the result of the procedure. We present a novel catheter design which integrates a unique origami deployable mechanism for enabling parallel MR imaging in MRI guided EP procedures.
