Patent number: 10724534Abstract: A blood pump includes a housing and a rotor within the housing configured to rotate along an axis. The rotor may include a hub, the hub having regions with blades and regions without blades. The regions without blades may have a constant outer diameter and may extend along at least one fourth the length of the hub. The regions with blades may have an increasing outer diameter. Blades may be disposed on a downstream end region of the hub and extend downstream of the hub. Blades may begin approximately halfway along the axial length of a motor stator located about a hub and extend downstream of the motor stator. Blades may have portions that produce axial fluid flow and radial fluid flow with improved flow characteristics.Type: GrantFiled: November 25, 2015Date of Patent: July 28, 2020Assignee: TC1 LLCInventors: Yi-Ren Woo, Onur Dur, Steven H.

Patent number: 10702641Abstract: Blood pumps for ventricular assist devices employ a hollow rotor to impel blood through the blood pump. A blood pump includes a housing having a housing inlet, a housing outlet, and a housing blood flow channel through which the housing inlet and the housing outlet are in fluid communication. A motor stator is disposed around the housing blood flow channel and operable to generate a rotating magnetic field. A hollow rotor is disposed within the housing blood flow channel and rotated via the rotating magnetic field. The hollow rotor has a rotor circumferential wall enclosing a rotor blood flow channel. The hollow rotor has at least one rotor blade extending inwardly from the rotor circumferential wall. The at least one rotor blade is configured to impel blood through the rotor blood flow channel when the hollow rotor is rotated via the rotating magnetic field.Type: GrantFiled: June 29, 2016Date of Patent: July 7, 2020Assignee: TC1 LLCInventors: Eric T. Lee, William V. Hodges, Yi-Ren Woo

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.
