  • Publication number: 20210106336
    Abstract: A method of using an occlusion clamp, the method comprising: (a) repositioning a tongs so that tissue interposes the tongs, the tongs comprising a first longitudinal segment operatively coupled proximally to a second longitudinal segment, the tongs including a first spring exerting a proximal bias tending to direct a proximal portion of each of the first and second longitudinal segments toward one another, where each of the first and second longitudinal segments includes a distal free end; (b) repositioning a second spring distally along each of the first and second longitudinal segments to exert a bias tending to direct a distal portion of each of the first and second longitudinal segments toward one another, where repositioning of the tongs so that tissue interposes the tongs precedes repositioning the second spring distally along each of the first and second longitudinal segments.

  • Patent number: 10932849
    Abstract: 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.

  • Patent number: 10932851
    Abstract: 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.

  • Publication number: 20210007794
    Abstract: 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 RF energy sources, other energy sources, such as microwave, may be used.

  • Publication number: 20200352656
    Abstract: Methods of performing surgical operations and associated devices are disclosed. An example method may include locating a first position on a first surface of a biological tissue; locating a second position on a second opposing surface of the biological tissue, the second position corresponding to the first position; and marking the second position on the second surface. The second surface may be generally opposite the first surface. An example method may include, after marking the second position, performing a therapeutic procedure on the biological tissue in the vicinity of the second position.

  • 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: 10758243
    Abstract: Apparatus and methods for delivering a surgical clip to a patient during a minimally invasive surgical procedure are disclosed herein. An exemplary apparatus for isolating an atrial appendage of a patient includes a surgical clip that locks onto the atrial appendage of the patient, and a surgical clip applicator that releasably engages the surgical clip. The surgical clip can include a top portion and a bottom portion. The surgical clip applicator can include a first flexible flap and a second flexible flap. The first and second flexible flaps can be sufficiently rigid to prevent the surgical clip from falling off of the surgical clip applicator when the surgical clip is engaged to the surgical applicator and the surgical clip applicator is in a relaxed state, and sufficiently flexible to facilitate separation of the surgical clip from the surgical clip applicator when the surgical clip is locked onto the atrial appendage.
