Safety and Effectiveness Evaluation of the Multi-Electrode Radiofrequency Balloon Catheter for the Treatment of Symptomatic Paroxysmal Atrial Fibrillation

Phase 3
Completed
Conditions
Atrial Fibrillation
Interventions
Device: Multi-Electrode RF Balloon Catheter
Registration Number
NCT03683030
Lead Sponsor
Biosense Webster, Inc.
Brief Summary

The primary objective of this clinical investigation is to demonstrate safety and effectiveness of the Multi-Electrode RF Balloon catheter for the treatment of drug refractory symptomatic paroxysmal atrial fibrillation.

Detailed Description

The STELLAR study is a pivotal, prospective, multicenter, single-arm, clinical evaluation of the Multi-Electrode RF Balloon catheter. The study will evaluate the safety and effectiveness of the Multi-Electrode RF Balloon catheter used for ablation in patients with paroxysmal atrial fibrillation (PAF).

  • Presence of implanted pacemaker or implantable cardioverter defibrillator (ICD).
  • Women who are pregnant, lactating, or who are of child bearing age and plan on becoming pregnant during the course of the clinical investigation.
  • Life expectancy or other disease processes likely to limit survival to less than 12 months.

NameTimeMethod
Incidence of early onset Primary Adverse Events7 days

Primary Adverse Events (PAEs) occuring within 7 days of an ablation procedure which uses the Multi-Electrode Radiofrequency Balloon Catheter. (Including atrio-esophageal fistula and PV stenosis occurring greater than seven (7) days post ablation procedure.)

Freedom of arrhythmia recurrence3 - 12 months

The primary effectiveness endpoint for this study will be freedom from documented asymptomatic and symptomatic Atrial Fibrillation (AF), Atrial Tachycardia (AT), or Atrial Flutter.
