摘要: 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.

摘要: Embodiments of the invention provide an ablation apparatus for ablating target tissue adjacent pulmonary veins of a patient. The ablation apparatus can include a tube capable of being advanced around the pulmonary veins to form a loop. The tube can receive or include electrodes to ablate target tissue. Some embodiments provide a loop ablation device, which may include a cannula and two or more electrode rods carrying two or more bipolar electrodes. The electrode rods can be advanced through the distal ends toward the proximal ends of the loop and toward the target tissue. The bipolar electrodes can receive energy to ablate the target tissue. The bipolar electrodes may be surrounded by the liquid within the cannula while ablating the target tissue. The loop ablation device can further include a rotating grasping mechanism coupled to the electrode rods.
