  • Publication number: 20210307823
    Abstract: A method of perforating a tissue of a heart of a patient when an inferior approach to the heart is contraindicated. The method utilizes an electrosurgical apparatus having an energy delivery device which can function as an ECG measuring device at a distal end thereof and a delivery system comprising a dilator. Said method comprises the steps of (a) advancing the dilator through a superior vena cava into the heart of the patient, from a superior approach, until a distal end of the dilator is adjacent the tissue; (b) checking an ECG signal to confirm a position of the energy delivery device; (c) using the electrosurgical apparatus, which is positioned through the dilator, to create a perforation in the tissue by delivering electrical energy to the tissue; (d) advancing the distal end of the electrosurgical apparatus through the perforation; and (e) advancing the dilator over the electrosurgical apparatus.

  • Patent number: 10610297
    Abstract: A device for treating spinal tissue of a patient's body may include an energy source and first and second probe assemblies. Each of the probe assemblies may have an electrically conductive energy delivery device electrically coupled to the energy source, and may also have an electrothermal device for cooling the probe assembly. The device is configured so that the energy source delivers energy to the spinal tissue through the energy delivery devices in a bipolar mode that concentrates delivered energy between the energy delivery devices to create a lesion within the spinal tissue while the electrothermal devices cool the probe assemblies. Related methods of use include cooling, at times via an electrothermal device.

  • Patent number: 10493259
    Abstract: This disclosure describes embodiments of a kit and its constituent components which together form an apparatus in which fluid communication between a medical device's lumen and the surrounding environment is provided by a conduit cooperatively defined by the medical device and a tubular member into which the device is inserted. The medical device and tubular member are configured to fit together such that an outer surface of the distal region of the medical device cooperates with an inner surface of the tubular member to define the conduit between the side-port of the medical device and a distal end of the tubular member. The conduit is operable to be used for injecting fluid, withdrawing fluid, and measuring pressure, for example. Methods of assembling and using the apparatus are described as well.

  • Patent number: 9597146
    Abstract: Apparatuses and methods for the perforation of heart tissue of a patient when an inferior approach to the heart is contraindicated are disclosed. The method includes using a superior approach to introduce the apparatus, positioning the apparatus at a tissue location and delivering a controlled amount of non-mechanical energy to the tissue to create a perforation. For example, a method of surgical perforation via the delivery of electrical, radiant or thermal energy may include: introducing an apparatus comprising an energy delivery device into a patient's heart via the patient's superior vena cava; positioning the energy delivery device at a first location adjacent material to be perforated; and perforating the material by delivering energy via the energy delivery device; wherein the energy is selected from the group consisting of electrical energy, radiant energy and thermal energy.

  • Patent number: 9216053
    Abstract: An elongate member for inserting into a cannula is disclosed. The cannula comprises an electrically insulated region and an electrically exposed conductive region for delivering energy to form a lesion within a patient's body at an intended location relative to the electrically exposed conductive region. The elongate member is structured to cooperatively engage with the cannula at a pre-determined insertion depth and to provide a variation in radiopacity, at a pre-determined position relative to the electrically exposed conductive region, when inserted to the pre-determined insertion depth. The variation in radiopacity provides a visual reference for distinguishing, using fluoroscopic imaging, the intended location of the lesion.
