Publication number: 20240341787Abstract: 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.Type: ApplicationFiled: June 26, 2024Publication date: October 17, 2024Applicant: Shockwave Medical, Inc.Inventors: Hoa D. NGUYEN, John M. ADAMS

Patent number: 12114923Abstract: 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.Type: GrantFiled: May 23, 2023Date of Patent: October 15, 2024Assignee: Shockwave Medical, Inc.Inventors: John M. Adams, Thomas G. Goff, Doug Hakala

Patent number: 12102161Abstract: 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.Type: GrantFiled: January 19, 2024Date of Patent: October 1, 2024Inventors: George Papadopoulos, John M. Adams

Patent number: 12102342Abstract: 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.Type: GrantFiled: April 15, 2021Date of Patent: October 1, 2024Assignee: SHOCKWAVE MEDICAL, INC.Inventors: Daniel Hawkins, John M. Adams

Patent number: 12096950Abstract: 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.Type: GrantFiled: February 3, 2023Date of Patent: September 24, 2024Assignee: SHOCKWAVE MEDICAL, INC.Inventors: Doug Hakala, John M.

Publication number: 20240008886Abstract: 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.Type: ApplicationFiled: August 8, 2023Publication date: January 11, 2024Applicant: Shockwave Medical, Inc.Inventor: John M. ADAMS

Publication number: 20230043475Abstract: 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.Type: ApplicationFiled: August 10, 2022Publication date: February 9, 2023Inventor: John M.
