Abstract

A hemostat-type device for ablative treatment of tissue, particularly for treatment of atrial fibrillation, is constructed with features that provide easy and effective treatment. The device may include a swiveling head assembly that allows the jaws to be adjusted in pitch and/or roll. The device may include a malleable or articulating handle shaft, as well as, malleable or curved rigid jaws that can permit curved lesion shapes. A locking detent can secure the jaws in a closed position during the procedure. The device may include one or more remote actuators making the hemostat-type device useful for minimally invasive procedures.
