A surgical system for ablating a tissue, the system comprising: (a) an ablation mechanism comprising a first electrode and an opposed second electrode, wherein the ablation mechanism is configured to receive a tissue between the first electrode and the second electrode, and wherein at least one of the first electrode and the second electrode is movable to allow the first electrode and the second electrode to accommodate variable tissue thicknesses therebetween; and (b) a clamping mechanism configured to release and apply clamping pressure to the tissue between the first electrode and the second electrode, where the ablation mechanism is configured to automatically individually adjust at least one of an ablation energy output of the first electrode and an ablation energy output of the second electrode to accommodate variable tissue thicknesses between the first electrode and the second electrode.

Stabilized ablation systems and methods

Surgical systems and methods for administering an ablation treatment and other therapeutic or diagnostic protocols to a patient tissue involve a flexible stabilizer mechanism having an inner recess and an ablation mechanism coupled with the stabilizer mechanism.

Systems and methods for forming a lesion on an endocardial tissue of a patient's heart involve placing an ablation assembly inside of the heart and adjacent to the endocardial tissue, and placing a guiding assembly outside of the heart. An ablation assembly includes an ablation element and a first attraction element, and a guiding assembly includes a second attraction element. First and second attraction elements can be attracted via magnetism. Techniques involve forming an ablation on the cardiac tissue of a patient's heart with an ablation element of the ablation assembly. Optionally, techniques may include moving the second attraction element of the guiding assembly relative to the patient's heart, so as to effect a corresponding movement of the ablation element of the ablation assembly.

Magnetic navigation systems and methods

Tissue treatment systems for cardiac surgical procedures can include an ablation and monitoring assembly having a first ablation element, a second ablation element, and a monitoring mechanism. Treatment methods may involve placing an ablation and monitoring assembly of the tissue treatment system at a patient tissue treatment site, applying a first ablative energy to a first tissue location via the first ablation element and a second ablative energy to a second tissue location via the second ablation element, monitoring a condition of the first tissue location with the monitoring mechanism, and modulating application of the first ablative energy to the first tissue location in response to the condition of the first tissue location while maintaining application of the second ablative energy to the second tissue location. Embodiments also include techniques for assessing a conduction delay across a lesion that involve evaluating local activation rates on various sides of a lesion.

Conduction block systems and methods

High-voltage pulses ablation systems and methods are used to ablate tissue and form lesions. A variety of different electrophysiology devices, such as catheters, surgical probes, and clamps, may be used to position one or more electrodes at a target location. Electrodes can be connected to power supply lines and, in some instances, the power to the electrodes can be controlled on an electrode-by-electrode basis. High-voltage pulse sequences provide a total amount of heating that is typically less than that which is observed with thermally-based radiofrequency energy ablation protocols.

High-voltage pulse ablation systems and methods

Bipolar belt ablation systems and methods for treating patient tissue involve the use of an ablation an ablation apparatus with a plurality of ablation elements carried by a flexible tube structure, a radiofrequency generator capable of delivering a plurality of differing radio frequency power signals to the ablation elements of the ablation device, wires transmitting the radiofrequency power signals from the radiofrequency generator to the ablation elements, and a control mechanism to enable temperature-based power control to each of the powered ablation elements.

Bipolar belt systems and methods

Devices, systems, and methods for treating a heart of a patient may make use of structures which limit a size of a chamber of the heart, such as by deploying one or more tensile member to bring a wall of the heart and a septum of the heart into contact. A plurality of tension members may help exclude scar tissue and provide a more effective remaining ventricle chamber. The implant may be deployed during beating of the heart, often in a minimally invasive or less-invasive manner. Trauma to the tissues of the heart may be inhibited by selectively approximating tissues while a pressure within the heart is temporarily reduced. Three-dimensional implant locating devices and systems facilitate beneficial heart chamber volumetric shape remodeling.

Location, time, and/or pressure determining devices, systems, and methods for deployment of lesion-excluding heart implants for treatment of cardiac heart failure and other disease states

Devices, systems, and methods for treating a heart of a patient may make use of one or more implant structures which limit a size of a chamber of the heart, such as by deploying a tensile member to bring a wall of the heart toward (optionally into contact with) a septum of the heart.

Steerable lesion excluding heart implants for congestive heart failure

Systems and methods for forming a lesion on an endocardial tissue of a patients heart involve placing an ablation assembly inside of the heart and adjacent to the endocardial tissue, and placing a guiding assembly outside of the heart. An ablation assembly includes an ablation element and a first attraction element, and a guiding assembly includes a second attraction element. First and second attraction elements can be attracted via magnetism. Techniques involve forming an ablation on the cardiac tissue of a patient's heart with an ablation element of the ablation assembly. Optionally, techniques may include moving the second attraction element of the guiding assembly relative to the patient's heart, so as to effect a corresponding movement of the ablation element of the ablation assembly.

Systems and methods provide protection for patient tissue during radiofrequency ablation treatments. Exemplary techniques involve placing a conductive or semiconductive pad assembly near a target tissue, and administering electrical current through the target tissue while protecting adjacent tissue with the pad assembly. The pad assembly may include a material having an electrical conductivity value that is equal to or greater than the electrical conductivity value of the target tissue.
