  • Patent number: 10492845
    Abstract: Volumetrically oscillating plasma flows, the volume of which controllably expands and contracts with time, are disclosed. Volumetrically oscillating plasma flows are generated by providing an energy with a power density that changes with time to the plasma-generating gas to form a plasma flow. The changes in the energy power density result in plasma flow volumetric oscillations. Volumetric oscillations with a frequency of above 20,000 Hz results in ultrasonic acoustic waves, which are known to be beneficial for various medical applications. System for providing volumetrically oscillating plasma flows and a variety of surgical non-surgical applications of such flows are also disclosed.

  • Patent number: 10485602
    Abstract: A cryosurgical apparatus with a temperature regulator. For better therapeutic success, it is desirable to set the temperature applied to a cryosurgical instrument as exactly as possible. Conventional apparatuses have corresponding temperature sensors allowing the regulation of the cooling power in the cryosurgical instrument such that the cooling power corresponds to a predefined value. However, the dimensions of some temperature sensors prevent them from being provided within a cryoprobe. Furthermore, suitable temperature sensors are expensive and have low durability. This problem is solved by the disclosed temperature regulator for regulating the temperature of a cryoprobe, which supplies an at least partly liquid refrigerant at a first pressure to an evaporation region such that the coolant evaporates at least temporarily under the presence of a second pressure for cooling a cooling portion of the cryoprobe. A pressure setting means that sets at least the second pressure is also provided.

  • Patent number: 10441353
    Abstract: The tissue cutting device comprises an elongated assembly including both an outer sleeve and an inner sleeve. The outer sleeve has a tissue-receiving window, and the inner sleeve has a distal end which cuts tissue as the inner sleeve is advanced past the window. The tissue is received into a lumen of the inner sleeve, and the inner sleeve lumen is typically enlarged in a proximal direction to reduce the tendency of resected tissue to lodge therein. The tissue displacement member is optionally provided at a distal end of the outer sleeve to further aid in dislodging tissue which becomes captured in a distal end of the inner sleeve of the lumen.

  • Patent number: 10390873
    Abstract: An energy delivery probe is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. In some embodiments, the energy can be applied with a vapor media. The energy delivery probe can include a vapor delivery member configured to extend into a transition zone prostate tissue. A condensable vapor media can be delivered from the vapor delivery member into the transition zone tissue, wherein the condensable vapor media can propagate interstitially in the transition zone tissue and be confined in the transition zone tissue by boundary tissue adjacent to the transition zone tissue. Methods associated with use of the energy delivery probe are also covered.

  • Patent number: 10271794
    Abstract: Location data associated with a cardiac wall motion during a cardiac cycle can be received. The cardiac cycle can be divided into incremental phases. The location data associated with the cardiac wall motion can be assigned to the incremental phases. A fiducial pair of coordinates can be determined for each of the incremental phases. The fiducial pair of coordinates can include location data for an intermediate cardiac phase and location data for a reference cardiac phase. A fiducial loop can be determined from the fiducial pair of coordinates for each of the incremental phases. A learned cardiac mapping between the reference cardiac phase and the intermediate cardiac phase can be determined using the fiducial loop.
