Publication number: 20230329731Abstract: 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: ApplicationFiled: February 3, 2023Publication date: October 19, 2023Applicant: Shockwave Medical, Inc.Inventors: Doug HAKALA, John M. ADAMS, Randy HOLMBERG

Patent number: 11403386Abstract: In one implementation, a system for detecting counterfeit accessories that are consumable, disposable, or otherwise user replaceable is disclosed. The system includes a host controller, a processor, and a computer-readable storage medium that includes instructions. Upon execution by the processor, the instructions cause the system to perform operations. The operations include obtaining an identifier of an accessory, a current value of usage data for the accessory, and a usage digest of the current value from a storage device associated with the accessory. An expected usage digest is generated based on the current value, the identifier, and a host secret. The expected usage digest is compared with the usage digest and the current value with a threshold usage value. The accessory is activated with the host controller responsive to the expected usage digest being identical to the usage digest and the current value satisfying the threshold usage value.Type: GrantFiled: August 30, 2019Date of Patent: August 2, 2022Assignee: Bausch Health Ireland LimitedInventors: Richard L. Fix, Randy Holmberg

Publication number: 20200022716Abstract: A method of delivering shock waves to treat calcified lesions includes advancing an angioplasty balloon mounted on a carrier, to reach the calcified lesion. A pair of electrodes is located within the balloon. The balloon is filled with a conductive fluid. A series of high voltage pulses are supplied to the electrodes. Each voltage pulse has sufficient energy to generate an arc in the fluid and allows current to flow across the pair of electrodes to produce a shock wave. During each pulse, the current flowing across the pair of electrodes is monitored. When the sensed current reaches a predetermined value, that voltage pulse is terminated. The predetermined value is selected to be high enough to ensure the creation of the arc while compensating for the variable dwell time between initial application of a given voltage pulse and creation of the arc.Type: ApplicationFiled: August 28, 2019Publication date: January 23, 2020Inventors: Doug HAKALA, John M.

Patent number: 9138249Abstract: A shock wave catheter system and method produces a shock wave with reduced energy. The system includes a catheter and a power source. The catheter has an elongated carrier and a balloon about the carrier in sealed relation thereto. The balloon is arranged to receive a fluid therein that inflates the balloon. The catheter further includes an arc generator including at least two electrodes within the balloon. The power source is coupled to the at least two electrodes and is configured to grow a bubble at one of the at least two electrodes and then thereafter to rapidly expand the bubble to form a shock wave within the balloon.Type: GrantFiled: February 26, 2013Date of Patent: September 22, 2015Assignee: SHOCKWAVE MEDICAL, INC.Inventors: John Adams, Randy Holmberg
