  • Patent number: 11813015
    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.

  • Patent number: 11771892
    Abstract: Bacteria, cancer cells, fungus and other harmful cells located beneath the surface of a mammal body can be effectively destroyed by passing an electrical current through the area to be treated. Electrodes are positioned on either side of the area to be treated, for example, gums, fingers, arms, legs, feet and torso, and an electric current is caused to flow between the electrodes and through the area to be treated. The electric current will destroy the bacteria, cancer cells, fungus or other harmful cells.

  • Patent number: 11766289
    Abstract: A surgical instrument includes first and second shaft members defining proximal and distal end portions and including handles at the proximal end portions thereof. A pivot member couples the distal end portions with a gap defined therebetween proximally of the pivot member. First and second jaw members extend distally from the shaft members, distally of the pivot member. A lockout bar is movable between an unlocked position, withdrawn from the gap, and a locked position, disposed within the gap. The handles are pivotable between spaced-apart and approximated positions to pivot the jaw members between open and closed positions. The handles are yawable between the approximated position and a yawed position to yaw the jaw members between the closed position and a cutting position. The gap provides clearance to permit yawing such that, when the lockout bar is disposed in the locked position, yawing of the handles is inhibited.

  • Patent number: 11737808
    Abstract: The recovery of an intact volume of tissue proceeds with a delivery cannula distal end positioned in confronting adjacency with the volume of tissue to be recovered. A tissue cutting and capture assembly formed of a plurality of metal leafs is deployed from the distal end of the delivery cannula. The tips of these leafs carry a pursing cable assembly, which is resistively heated by the passage of electrical current through the cable, attaining temperature level sufficient to thermally cut around and circumscribe the tissue volume. These pursing cables are tensioned to complete the envelopment of the tissue volumes by drawing the leaf tips together. An essential attribute of the disclosed apparatus is the confinement of the path of electrical conduction of constant current required to achieve tissue cutting to only those portions of the deploying and retracting resistively heated portion of the electrically conductive cutting and pursing cable that are in direct contact with tissue.

  • Patent number: 11723680
    Abstract: Conventional vasectomy techniques suffer from a number of disadvantages and potential complications, including, for example, a substantial risk for the development of hematomas, swelling, and post-surgical pain, a potential for spontaneous regeneration and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The present invention overcomes the disadvantages and deficiencies of the prior art by providing vasectomy instruments, kits, and methods that allow for a rapid, reliable, less invasive male sterilization procedure that may be readily, reliably and successfully performed by minimally skilled personnel around the world in a variety of medical settings.

  • Patent number: 11696798
    Abstract: A vessel sealing device having a pair of electrodes that are maintained in spaced apart configuration when closed by non-uniform coating formed from a non-conductive material that has been applied to roughened electrodes so that the coating allows for the passage of a predetermined amount of radiofrequency (RF) energy between the electrodes. The coating has a predetermined thickness that spaces the electrodes apart while also having the predetermined non-uniformity that allows RF energy to pass between the electrodes when a vessel is trapped therein, thus desiccating the vessel positioned in the jaws. The electrodes may include a series of grooves in a herringbone pattern, with each electrode having the pattern oriented in the same direction or in opposite directions.
