Patent number: 11883641Abstract: 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: GrantFiled: November 8, 2022Date of Patent: January 30, 2024Assignee: TC1 LLCInventors: Onur Dur, Kevin Bourque

Publication number: 20230363896Abstract: Artificial heart valve structures and methods of their fabrication are disclosed. The heart valve structures may be fabricated from a biocompatible polymer and include one or more heart valve leaflet structures incorporated within a conduit. The valve structures may incorporate one or more conduit sinuses, as well as a gap between the lower margin of the valve leaflets and the interior of the conduit. In addition, the valve structures may include one or more valve sinuses created in a space between the valve leaflets and the conduit inner surface. Computational fluid dynamics and mechanical modeling may be used to design the valve leaflets with optimal characteristics. A heart valve structure may also incorporate a biodegradable component to which cells may adhere. The incorporated cells may arise from patient cells migrating to the biodegradable component, or the component may be pre-seeded with cells prior to implantation in a patient.Type: ApplicationFiled: April 24, 2023Publication date: November 16, 2023Applicants: CARNEGIE MELLON UNIVERSITY, UNIVERSITY OF PITTSBURGH - OF THE COMMONWEALTH SYSTEM OF HIGHER EDUCATIONInventors: Masahiro YOSHIDA, C.

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.
