Patent number: 11950801Abstract: An atherectomy system includes a handle having a handle housing, with a drive member extending through the handle housing and operably coupled to an atherectomy burr. A drive mechanism is disposed within the handle housing and is adapted to rotatably engage the drive member. The drive mechanism may include an electric drive motor, a drive gear that is rotatably engaged with the electric drive motor and a driven gear that is coupled with the drive member and is engaged with the drive gear such that rotation of the driven gear causes rotation of the drive member. The drive mechanism may be configured to enable a rotation speed of the atherectomy burr of up to at least about 200,000 revolutions per minute (rpm).Type: GrantFiled: January 17, 2020Date of Patent: April 9, 2024Assignee: Boston Scientific Scimed, Inc.Inventors: Robert Rawson, Laszlo Trent Farago, David Gordon Spangler, Daniel Frank Massimini

Patent number: 11931058Abstract: An atherectomy system includes a handle and a drive motor that is adapted to rotate a drive cable extending through the handle and operably coupled to an atherectomy burr. A control system is adapted to regulate operation of the drive motor, including providing the drive motor with a high frequency pulse width modulation (PWM) drive signal in order to operate the drive motor. The control system monitors a motor performance parameter such as motor speed or motor torque, and when the motor performance parameter approaches a limit of a performance range, the control system adds a low frequency PWM signal to the high frequency PWM drive signal, thereby causing the drive motor to produce a tactile signal that signals to the user that the motor performance parameter is approaching the limit of the performance range.Type: GrantFiled: January 19, 2021Date of Patent: March 19, 2024Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: David Gordon Spangler, Corydon Carlson, Laszlo Trent Farago, Daniel Frank Massimini, Mark A.

Patent number: 11819238Abstract: Medical systems and methods for making and using medical systems are disclosed. Example medical systems may include an atherectomy system configured to engage and remove plaque from walls in vessels of a vascular system. The atherectomy system may include a drive shaft, a rotational tip coupled to an end of the drive shaft, a motor coupled to the drive shaft to rotate the rotational tip, and a controller configured to control a motor state of the motor. The controller may adjust a range of possible load outputs from the motor and/or a maximum load output from the motor to account for external loads acting on the drive shaft and/or rotational tip rotated by the motor and facilitate passing an occlusion in a vasculature of a patient.Type: GrantFiled: January 27, 2022Date of Patent: November 21, 2023Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Laszlo Trent Farago, David Gordon Spangler

Patent number: 11696782Abstract: Medical systems and methods for making and using medical systems are disclosed. Example medical systems may include an atherectomy system configured to engage and remove plaque from walls in vessels of a vascular system. The atherectomy system may include a drive shaft, a rotational member coupled to an end of the drive shaft, a motor coupled to the drive shaft to rotate the rotational tip, and a control unit configured to control a motor state of the motor. The motor may be an electric motor. The control unit may adjust the motor state to decelerate the motor in response to detecting a jam or a stall condition. The jam or stall condition may be detected when a speed of the motor or other motor state reaches or goes beyond a threshold value as prescribed by a reference schedule.Type: GrantFiled: December 11, 2018Date of Patent: July 11, 2023Assignee: Boston Scientific Scimed, Inc.Inventors: Corydon Carlson, David Gordon Spangler, Daniel Frank Massimini, Laszlo Trent Farago, Mark A.

Publication number: 20230047964Abstract: An atherectomy system includes a drive mechanism that is adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the drive mechanism. In some cases, the drive mechanism includes a drive cable that is coupled with the atherectomy burr and a drive motor that is adapted to rotate the drive cable. The controller is adapted to receive an indication of an increase in torque experienced at the atherectomy burr and is further adapted to, in response, regulate operation of the drive mechanism such that the increase in torque results in a noticeable reduction in speed of the drive mechanism such that a user of the atherectomy system notices the reduction in speed and is alerted to the increase in torque.Type: ApplicationFiled: October 19, 2022Publication date: February 16, 2023Applicant: Boston Scientific Scimed, Inc.Inventors: Corydon Carlson, David Gordon Spangler, Daniel Frank Massimini, Laszlo Trent Farago, Mark Alfred Hilse
