Patent number: 11534593Abstract: The present disclosure relates to a rotary blood pump system. The rotary blood pump system may comprise an inflow conduit, an outflow conduit, a control system, and a power source. The present disclosure further relates to various inflow conduit assemblies comprising a conduit tip comprised of metal or polymer having an undulating opening surface that provides improved blood flow and washing properties while minimizing regions susceptible to stagnation, and optionally a resilient tip-protecting cage structure that reduces the risk of conduit tip suction events and suction-related injury of the wall of adjacent blood vessels or other blood containing structures. The present disclosure further relates to various outflow conduit assemblies with a conduit tip comprised of metal or polymer wherein the cross-sectional area of the lumen of the conduit or conduit tip is reduced to generate a localized jet-like fluid flow in a blood vessel segment adjacent to the conduit tip.Type: GrantFiled: May 1, 2017Date of Patent: December 27, 2022Assignee: Artio Medical, Inc.Inventors: F. Nicholas Franano, Geoff Tansley, Steve Woodard, Barrett Hutto, J. Scott Richardson, Howard M. Loree, II

Patent number: 9662431Abstract: The present invention relates to a rotary blood pump with a double pivot contact bearing system with an operating range between about 50 mL/min and about 1500 mL/min. The rotary blood pump is part of a blood pump system that includes blood conduit(s), a control system with optional sensors, and a power source. Embodiments of the present invention may include elements such as wear resistant bearing materials, a rotor back plate for magnetic attraction of the rotor to reduce bearing pivot bearing forces and wear, a rotor size and shape and a bearing gap that combine to create a hydrodynamic bearing effect and reduce bearing pivot bearing forces and wear, improved intravascular conduits with increased resistance to thrombosis, conduit insertion site cuffs to resist infection, and conduit side ports amenable to the easy insertion of guidewire and catheter-based medical devices.Type: GrantFiled: August 15, 2013Date of Patent: May 30, 2017Assignee: FLOW FORWARD MEDICAL, INC.Inventors: F.
