Summary
Brief summary
This clinical investigation is intended to demonstrate the acute safety and effectiveness of
ablation with the TactiCath™ Contact Force Ablation Catheter, Sensor Enabled™ (TactiCath SE)
for the treatment of drug refractory recurrent symptomatic paroxysmal atrial fibrillation
(PAF). This clinical investigation will be conducted under an investigational device
exemption (IDE) and is intended to support market approval of the TactiCath SE ablation
catheter in the United States. One hundred fifty six (156) subjects will be enrolled at up to
35 investigational sites in the US, Europe, and Australia. This clinical investigation is
sponsored by Abbott.
