  • Patent number: 10893882
    Abstract: 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.

  • Publication number: 20200397464
    Abstract: An atherectomy system includes a drive mechanism adapted to rotatably actuate an atherectomy burr and a controller that is adapted to operate the drive mechanism in a first operating mode in which the atherectomy burr is operated at a speed reference and with a predetermined torque limit. The controller is adapted to determine when the atherectomy burr becomes stuck while in the first operating mode and is further adapted to, when the atherectomy burr becomes stuck, operate the drive mechanism in a second operating mode that is different from the first operating mode.

  • Publication number: 20190262032
    Abstract: 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.

  • Publication number: 20190262034
    Abstract: An atherectomy system includes a drive mechanism adapted to rotatably actuate an atherectomy burr and a control system that is adapted to regulate operation of the drive mechanism. The drive mechanism may include a drive cable that is coupled with the atherectomy burr and a drive motor that is adapted to rotate the drive cable. The control system includes a drive module adapted to provide an operational signal to operate the drive mechanism, a monitoring module adapted to monitor operation of the drive mechanism and to determine if the drive mechanism is operating within a predetermined range and an excitation module that is operably coupled to the drive mechanism and is adapted to provide haptic feedback to a user of the drive mechanism if the monitoring module determines that the drive mechanism is not operating within a predetermined range.

  • Publication number: 20190175211
    Abstract: 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.

  • Publication number: 20180235743
    Abstract: A medical device may include an elongate tubular member defining a tube lumen, and an expandable member disposed on the distal portion of the elongate tubular member including a lumen that is in fluid communication with the tube lumen. The expandable member is configured to expand from a collapsed delivery configuration to a distally-open expanded configuration and establish apposition with a vessel wall. A valve member in fluid communication with the tube lumen, and configured to selectively block and selectively allow for flow through the tube lumen. The device may be percutaneously-deployable downstream of a treatment site within a body lumen and may allow for selective removal and/or draining of fluid and/or material, such as embolic material, from a body lumen.

  • Publication number: 20070073233
    Abstract: A thrombectomy catheter deployment system which greatly simplifies setup procedures and operation of a thrombectomy catheter includes a stand alone drive unit and a disposable pump/catheter assembly which is manually placed into a carriage assembly in the drive unit. The pump/catheter assembly has a plurality of preconnected components including tubular structure and a thrombectomy catheter connected thereto and is transported into or out of the interior of the drive unit for automatic high pressure pump piston head engagement or disengagement with a reciprocating linear actuator and for automatic engagement or disengagement of an effluent waste tube with a roller pump. A barcode reader senses specific operational data pertaining to an individual pump and provides an interface for operation of the reciprocating linear actuator. A bubble trap incorporated for effective debubbling of saline solution is closely coupled to an insert molded pump having an improved valve arrangement.

  • Patent number: 5154052
    Abstract: An exhaust assembly is provided for a gas turbine engine effective for propelling an aircraft from takeoff through subsonic and supersonic velocity. The exhaust assembly is effective for receiving exhaust gases discharged from an outlet of a core engine of an aircraft gas turbine engine. The assembly includes a casing, a variable area converging-diverging nozzle attached to the casing and including a first throat and an outlet for channeling exhaust gases received from the core engine. A plurality of retractable chutes are disposed upstream of the nozzle outlet and are positionable in a deployed position forming a converging nozzle having a second throat with a flow area less than that of the first throat. Means are provided for channeling air along aft facing surfaces of the chutes into the CD nozzle for mixing with the exhaust gases when the chutes are disposed in the deployed position for reducing noise from the exhaust gases.
