    摘要： Methods and devices are disclosed herein for therapeutically treating atrial tissue to lessen the effects of mechanical stress on atrial tissue, where reducing mechanical stress in the portion of atrial tissue reduces formation of at least one arrhythmia substrate. In one example, the devices and methods are suitable for minimally invasive surgery. More particularly, methods and devices described herein permit creating an ablation pattern on an organ while reducing excessive trauma to a patient.

    摘要： 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.

    摘要： Medical devices and related methods, and, more specifically, cryogenic surgical systems and related methods are disclosed. Some example cryogenic surgical systems may include a cryosurgical control unit configured to cool a cryosurgical probe to a temperature colder than a temperature at which flow of cryogenic fluid to the probe is stopped. Some example tank level indicating systems may utilize the pressure of the fluid in the tank and a temperature of the exterior wall of the tank to indicate liquid level.

    摘要： An end effector positioning mechanism for a surgical device may include an articulation mechanism including a plurality of tiltable segments disposed generally in a longitudinal row between an elongated shaft of a surgical device and an end effector of the surgical device. Each of the plurality of segments may be generally in the form of a flattened disk. At least one of the segments may include a proximal surface and/or a distal surface that is substantially planar and is oriented substantially orthogonally with respect to a central axis of the articulation mechanism. At least one of the segments may include a proximal surface and/or a distal surface including two transversely oriented, generally planar surfaces that meet along a substantially diametric peak.

    摘要： An embodiment of the invention includes a surgical device for coagulating soil tissue such as atrial tissue in the treatment of atrial fibrillation, atrial flutter, and atrial tachycardia. The surgical device can include at least one elongate member comprising conductive elements adapted to coagulate soft tissue when radiofrequency or direct current energy is transmitted to the conductive elements. Openings through said conductive elements are routed through lumens in the elongate member to a vacuum source to actively engage the soft tissue surface intended to coagulate into intimate contact with the conductive elements to facilitate the coagulation process and ensure the lesions created are consistent, contiguous, and transmural. The embodiments of the invention can also incorporate cooling openings positioned near the conductive elements and coupled with a vacuum source or an injection source to transport fluid though the cooling openings causing the soft tissue surface to cool thus pushing the maximum temperature deeper into tissue. The embodiments of the invention can also incorporate features to tunnel between anatomic structures or dissect around the desired tissue surface to coagulate thereby enabling less invasive positioning of the soft tissue coagulating device and ensuring reliable and consistent heating of the soft tissue.

    摘要： A method and apparatus for ablating tissue are disclosed that comprise positioning two or more bi-directional ablation energy sources in spaced-apart relation in sufficient proximity to the tissue to be ablated so that, upon activation each energy source creates an energy field in the tissue to be ablated. The energy sources are spaced such that the energy fields created by at least one of the activated sources partially overlaps with the energy field created by one or more of the other energy sources. The energy sources are alternately activated and deactivated, so that a substantially constant energy field results where the energy fields created by at least two of the energy sources overlap. While the energy sources are preferably RE energy sources, other energy sources, such as microwave, may be used.
