  • Publication number: 20240341787
    Abstract: Disclosed herein shock wave catheters comprising one or more shock wave electrodes for cracking calcifications located within blood vessels. In some variations, a shock wave catheter has first and second shock wave electrodes each circumferentially disposed over the outer surface of the catheter. In certain variations, the first electrode has a recess and the second electrode has a protrusion that is received by the recess and a spark gap is located along the separation between the recess and the protrusion. The second electrode can also have a recess that receives a protrusion from a third shock wave electrode, where the separation between the second and third electrodes along the separation between the recess and the protrusion forms a second spark gap. A shock wave can be initiated across these spark gaps when a voltage is applied over the electrodes.

  • Patent number: 12114923
    Abstract: An apparatus includes a balloon adapted to be placed adjacent a calcified region of a body. The balloon is inflatable with a liquid. The apparatus further includes a shock wave generator within the balloon that produces shock waves that propagate through the liquid for impinging upon the calcified region adjacent the balloon. The shock wave generator includes a plurality of shock wave sources distributed within the balloon.

  • Patent number: 12102161
    Abstract: A helmet features a sound management mechanism within a hard exterior shell and an interior of expanded polystyrene foam. Ear cups embedded within the shell surround the ears, with a torus-shaped soft material forming a seal against the wearer's head. The helmet allows the transition of ear cups between engaged and disengaged positions. The engaged position is against the head. The disengaged position is away from the head, allowing easy placement and removing of the helmet. Positions may be transitioned using one hand. The helmet may include lateral adjustment of ear cups, and some versions incorporate electronic audio features like noise cancellation, communication capabilities, and wireless connectivity.

  • Patent number: 12102342
    Abstract: A valvuloplasty system comprises a balloon adapted to be placed adjacent leaflets of a valve. The balloon is inflatable with a liquid. The system further includes a shock wave generator within the balloon that produces shock waves. The shock waves propagate through the liquid and impinge upon the valve to decalcify and open the valve.

  • Patent number: 12096950
    Abstract: A system that breaks calcium in a liquid includes a catheter including first and second electrodes arranged to receive there-across a high electrical voltage at an initial low current. The high electrical voltage causes an electrical arc to form across the electrodes creating a gas bubble within the liquid, a high current to flow through the electrodes, and a mechanical shock wave. A power source provides the electrodes with the high electrical voltage at the initial current and terminates the high electrical voltage in response to the high current flow through the electrodes.

  • Publication number: 20240008886
    Abstract: Described herein are shock wave devices and methods for the treatment of calcified heart valves. One variation of a shock wave device includes three balloons that are each sized and shaped to fit within a concave portion of a valve cusp when inflated with a liquid and a shock wave source within each of the three balloons. Each balloon is separately and/or independently inflatable, and each shock wave source is separately and/or independently controllable. Methods of treating calcified heart valves using a shock wave device can include advancing a shock wave device having one or more balloons and a shock wave source in each of the balloons to contact a heart valve, inflating the one or more balloons with a liquid such that the balloon is seated within a concave portion of a valve cusp, and activating the shock wave source.

  • Publication number: 20230043475
    Abstract: A system includes a catheter including an elongated carrier, a balloon about the carrier in sealed relation thereto, the balloon being arranged to receive a fluid therein that inflates the balloon, and first and second electrodes within the balloon arranged to carry a voltage there-across including an initial high electrical voltage at an initial low current. The initial high electrical voltage causes an electrical arc to form across the first and second electrodes within the balloon. The electrical arc causes a gas bubble within the liquid, a high current to flow through the first and second electrodes, a decrease in the initial high electrical voltage, and a mechanical shock wave within the balloon. The system further includes a power source that provides the first and second electrodes with a drive voltage that creates the initial high electrical voltage at the initial current and that terminates the drive voltage in response to the decrease in the initial high electrical voltage.

  • Patent number: 11395671
    Abstract: A transoral gastroesophageal flap valve restoration device has sufficient flexibility and dimension to be passed through the mouth, throat, and esophagus of a patient into the patient's stomach. The device includes a first member and a second member hingedly coupled to the first member. The first and second members are configured to flex in a direction to follow the esophageal path into the stomach and to be substantially rigid when forming the restored gastroesophageal flap valve.
