GENESIS Feasibility Study of the BARD Over-the-Wire Mesh Ablation System

Status Completed

Clinical Trial Summary

The Genesis Feasibility Study will collect clinical information on the use of the Bard Over-the-Wire Mesh Ablation System to access and perform electrophysiological mapping, cardiac stimulation and radiofrequency ablation in the region of the pulmonary vein (PV) ostia for the treatment of patients with Paroxysmal Atrial Fibrillation. Patients will be followed up for 12 months to assess the primary safety endpoint of Major Complications (a composite safety endpoint)and effectiveness, defined as Long-Term Success (freedom from recurrent atrial arrhythmia.

Clinical Trial Description

Atrial fibrillation (AF) is the most common sustained arrhythmia seen by the physician. Its prevalence in the population increases with age, and it is estimated to affect over 4% of the population above the age of 60. Common approaches to AF management includes the use of anti-arrhythmic drugs to control the arrhythmia.

An alternative to treatment of AF using drug therapy is ablation of cardiac tissue, with the goal of disrupting the aberrant electrical pathways that cause AF through the creation of ablation lesions within the left atrium. There are several different approaches to creating lesions to treat AF, although both substrate derived and focal AF mechanisms share a common ablation therapy protocol in which the PVs are isolated by a series of ablation lines placed endocardially, either around the PV ostia or more proximally from the PV ostia at the atrial carinae.

The Over-the-Wire Mesh Ablation System (OTW MAS) catheter is a combined mapping and ablation catheter designed to create lesions at the PV ostium. The Genesis Feasibility Study is designed to collect clinical information on the use of the OTW MAS to access and perform electrophysiological mapping, cardiac stimulation and radiofrequency ablation in the region of the pulmonary vein (PV) ostia for the treatment of patients with Paroxysmal Atrial Fibrillation (PAF). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
