  • Patent number: 11419723
    Abstract: 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.

  • Publication number: 20210393321
    Abstract: 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.

  • Publication number: 20200315684
    Abstract: 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.

  • Patent number: 10751122
    Abstract: 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.
