Patent number: 10086122Abstract: In order to produce a pulsatile blood flow pattern that includes time periods of relatively high blood flow rates and time periods of relatively low blood flow rates, the operating speed of a blood pump can be selectively controlled to produce an operating speed pattern that includes time periods of relatively high rotation speeds and periods of relatively low rotation speeds. For example, the blood pump is rotated at a first speed for a first period of time. The speed of the blood pump is then decreased from the first speed to a second speed and is operated at the second speed for a second amount of time. The speed of the blood pump is then decreased to a third speed for a third amount of time. If desired, the operating speed pattern can be repeated to continue the pulsatile blood flow pattern.Type: GrantFiled: October 16, 2017Date of Patent: October 2, 2018Assignee: TC1 LLCInventor: Kevin Bourque

Publication number: 20180064861Abstract: The invention generally relates to improved medical blood pump devices, systems, and methods. For example, blood pumps may be provided that include a housing defining a blood flow path between an inlet and an outlet. A rotor may be positioned in the blood flow path. A motor stator may be driven to rotate the rotor to provide the blood flow through the pump. Axial and/or tilt stabilization components may be provided to increase an axial and/or tilt stabilization of the rotor within the blood flow path. In some embodiments, biasing forces are provided that urge the rotor toward a bearing component. The biasing force may be provided by adjusting drive signals of the motor stator. Additionally, or alternatively, one or more magnets (e.g., permanent/stator magnets) may be provided to bias the rotor in the upstream and/or downstream direction (e.g., toward a bearing (chamfer, step, conical), or the like).Type: ApplicationFiled: November 8, 2017Publication date: March 8, 2018Inventors: Onur Dur, Kevin Bourque

Patent number: 9872976Abstract: A percutaneous cable is attached to a mechanical cardiac pump and is passed through the skin. Sutures can be used to stabilize the cable against movement to prevent disturbing tissue surrounding cable and thereby reduce the incidence of infection. A funnel-shaped tubular device can be used where the cable exits the skin to allow the cable to flex below or near the skin surface as may be desired to accommodate physical activity of a patient. An anchor can be attached to the cable and implanted below the skin surface to stabilize the cable against movement. The anchor can include any one or a combination of a flat mesh material, a bundle of ultrafine filaments, and a barbed filament.Type: GrantFiled: August 19, 2011Date of Patent: January 23, 2018Assignee: THORATEC CORPORATIONInventors: Yi-Ren Woo, Steven H.

Publication number: 20170246365Abstract: A method for assisting blood circulation in a patient includes drawing a flow of blood from a patient's heart into a blood flow channel formed by a housing. The flow of blood is passed through a motor stator to a rotor disposed within the blood flow channel. The motor stator is arranged circumferentially around the blood flow channel. The rotor has permanent magnetic poles for magnetic levitation and rotation of the rotor. The motor stator is controlled to act as a radial bearing for magnetic levitation of the rotor and to rotate the rotor within the blood flow channel. The rotor is levitated within the blood flow channel in the direction of the rotor axis of rotation via passive magnetic interaction between the rotor and the motor stator. The flow of blood is output from the blood flow channel to the patient.Type: ApplicationFiled: May 12, 2017Publication date: August 31, 2017Inventor: Kevin Bourque

Patent number: 9694123Abstract: The present invention generally relates to ventricular assist device power monitoring and conservation. In some embodiments, a pump controller may transition the pump to operate in a power-saving operational mode when a power source and/or a power source condition indicate a need to conserve power. In some embodiments, when the power source is an emergency battery and when the emergency battery has powered the pump for an extended period of time, the controller may signal the pump to operate in the power saving-operational mode. In some embodiments, when a low power hazard condition is triggered by signals from one or more external power sources, the controller may signal the pump to transition to the power-saving operational mode if the condition lasts for an extended period of time. In some embodiments, the controller may trigger the power-saving mode when the emergency backup battery is below a voltage threshold.Type: GrantFiled: April 15, 2015Date of Patent: July 4, 2017Assignee: TC1 LLCInventors: Kevin Bourque, Brian Kimball, Charles P.
