The purpose of this study is to assess the safety and performance of the Hansen Medical Sensei Robotic System and Artisan Catheter when used to robotically manipulate the Biosense ThermoCool ablation catheter for the treatment of paroxysmal atrial fibrillation (irregular heartbeats originating in the upper chambers of the heart). The Biosense ThermoCool catheter is FDA approved for use in ablation therapy. The Hansen Medical Robotic Sensei System and Artisan catheter are approved in Europe for use during ablation procedures. This system has been used to treat atrial fibrillation in over 1000 patients worldwide by navigating existing, approved ablation catheters. In the US the Hansen Sensei System with Artisan catheter has FDA clearance as a robotic delivery system to facilitate manipulation, positioning and control of catheters used to collect electrophysiological data within the heart atria (upper chambers or the heart), but has not been studied or approved in the US for use in ablation treatment. This study is designed to evaluate safety, compatibility and effectiveness when the Hansen system is used with the ThermoCool ablation catheter in the treatment of paroxysmal atrial fibrillation. In this prospective,nonrandomized study, subjects will undergo treatment with robotic delivery of the of the ThermoCool ablation catheter. The primary effectiveness and safety outcomes must meet pre-established Target Performance Goals(chronic success rate is at least 54%; and, the major complication rate is no greater than 16%).

Primary Outcome Measures:
  • Safety - Incidence of Major Complications [ Time Frame: 0-7 days and 0-180 days ] [ Designated as safety issue: Yes ]

    The incidence of Major Complications, including the early onset (within 7 days of the procedure) predefined complications; and, the incidence of esophageal injury or pulmonary vein stenosis through day 180.

    Major Complications include the following adverse events.

    Major Complications through 0-7 days:

    • Death
    • Stroke
    • Myocardial infarction
    • Diaphragmatic paralysis
    • Transient ischemic attack (TIA)
    • Cardiac tamponade
    • Pericarditis
    • Pneumothorax
    • Hospitalization or Emergency Room visit
    • Vascular access complication
    • Heart block
    • Pulmonary edema
    • Pericardial effusion resulting in pericardiocentesis or surgical intervention
    • Thromboembolism

    Major Complications through 0-180 days:

    • Pulmonary vein stenosis
    • Atrio-esophageal fistula

  • Effectiveness - Chronic Success [ Time Frame: 91 - 365 days ] [ Designated as safety issue: No ]

    Chronic Success is defined as:

    • Freedom from symptomatic atrial arrhythmias from days 91 - 365.
    • No use of Class I or Class III antiarrhythmic medications.
    • No more than 2 ablation procedures within 90 days of the initial procedure and no ablation procedures after day 90.
    • No use of a non-study device for ablation of any atrial fibrillation target.
    • No ablation of an atrial fibrillation target made by manually manipulating the ThermoCool.
    • Pulmonary vein isolation of at least 3 out of 4 veins.
    • No surgical ablation for atrial arrhythmias within 90 days.
    • No DC cardioversion for atrial arrhythmias.
    • No catheter or surgical ablation for atrial arrhythmias.

Secondary Outcome Measures:
  • Chronic Safety [ Time Frame: 8 - 365 days and 181-365 days post-procedure ] [ Designated as safety issue: Yes ]
    Chronic safety is defined as the incidence of Major Complications during the period from 8-365 days following the initial ablation procedure, with the exception of Pulmonary Vein Stenosis and Atrio-Esophageal Fistula for which the incidence will be reported from 181-365 days post-procedure.

  • Acute Procedural Success [ Time Frame: Day 0 ] [ Designated as safety issue: No ]

    Acute procedural success is defined as the successful ablation of at least 3 of 4 pulmonary veins as shown by pulmonary vein entrance block per vein during the initial ablation procedure.

    A subject is considered to be an acute procedural failure if acute procedural success cannot be obtained by using the Hansen System, and as a result, manual manipulation is needed to complete the ablation procedure with the ThermoCool Catheter.

Estimated Enrollment: 250
