Patent number: 11911055Abstract: A lithotripter is provided for fragmenting a stone inside a patient's body. In one form, the lithotripter includes a motor having at least two modes of operation and is configured to produce first and second waveforms. A wave guide shaft is configured to transmit the first and second waveforms to the stone. In one form, at least one of the first and second waveforms is provided to the stone at a frequency that is about equal to a natural frequency of the stone. In a variation, the lithotripter may include an ultrasonic driver configured to produce an ultrasonic frequency waveform and a sonic driver configured to produce a sonic frequency waveform. The sonic driver is mechanically coupled to the ultrasonic driver. The ultrasonic driver and the sonic driver may be disposed within a driver housing. In another variation, the lithotripter may include a brushless DC motor.Type: GrantFiled: June 30, 2021Date of Patent: February 27, 2024Assignee: Gyrus ACMI, Inc.Inventors: Artemie G.

Patent number: 10117660Abstract: A lithotripter includes a motor operable to produce a rotational motion, a first cam with a first set of teeth, and a second cam with a second set of teeth configured to selectively engage with the first set of teeth. The first cam is coupled to the motor so that the rotational motion produced by the motor produces rotational motion of the first cam, and the selective engagement between the first set of teeth and the second set of teeth converts the rotational motion of the first cam to a linear waveform that is transmitted through the second cam. The motor, the first cam, and the second cam are disposed in a driver housing, and a wave guide shaft is coupled to the second cam. The wave guide shaft transmits the linear waveform to at least one urinary tract stone to break up the at least one urinary tract stone into fragments.Type: GrantFiled: March 10, 2015Date of Patent: November 6, 2018Assignee: GYRUS ACMI, INC.Inventors: Chris A.
