The Volt PFA System is an investigational device. This means that it is not yet approved for commercial use to treat atrial fibrillation, but it is approved for use in this Study. The Volt PFA System has gone through extensive testing in a laboratory setting to make sure it is safe to use and functions as it is expected to. An initial clinical study using the Volt PFA System was conducted to assess these characteristics when the Volt PFA System is used to treat humans. This research study will collect data to demonstrate safety and effectiveness for the treatment of atrial fibrillation. Data collected for this study will be used to obtain approval from authorities to bring the Volt PFA System on the market and make it available to other patients to treat atrial fibrillation.
