Medtronic Terminate AF Study
Sponsored by Medtronic Cardiac Surgery
About this study
The purpose of this study is to demonstrate the safety and effectiveness of the Cardioblate iRF and CryoFlex hand held devices for the treatment of non-paroxysmal atrial fibrillation (AF).
This is a multi-center, single-arm, prospective, non-randomized, interventional study. A maximum of 160 subjects will be treated at up to 25 centers in the United States (US). The study will include male and female patients with a history of non-paroxysmal atrial fibrillation who are undergoing concomitant cardiac surgery. Subjects will be followed and assessed after procedure and for 12 months. The purpose of this study is to evaluate the safety and effectiveness of the Cardioblate Surgical Ablation iRF and CryoFlex hand held devices to support an indication expansion to include treatment of persistent atrial fibrillation and long-standing persistent atrial fibrillation (non-paroxysmal atrial fibrillation) to the product labeling.
