Patent number: 11898961Abstract: A system, device and method for measuring markers for a periprosthetic joint infection in a sample of synovial fluid. A sensor reader device includes a vial receptacle for receiving a vial containing synovial fluid. A light source illuminates the vial and an optical sensor detects light scattered and/or absorbed by white blood cells in the fluid sample. An electrical signal corresponding to the intensity of the light received at the optical sensor is detected. A white blood cell concentration is determined from the electrical signal value. The sensor reader device also includes one or more immunoassay strip receptacles. Immunoassay strips for other marker are inserted into the receptacles. Immunoassay optical sensors detect light generated by the immunoassay reaction on the immunoassay strip to determine the concentration of the marker. In example implementations, the device includes an immunoassay strip reader for leukocyte esterase and c-reactive protein.Type: GrantFiled: April 2, 2020Date of Patent: February 13, 2024Assignee: Alio, Inc.Inventors: Forrest Miller, Samit Kumar Gupta, David John Kuraguntla, Elsa Swanson

Patent number: 11006845Abstract: Systems and methods for remotely monitoring blood flow that include an endovascular prosthesis. The endovascular prosthesis includes a conduit forming a lumen within a surrounding wall having an inner surface and an outer surface. A monitoring device is disposed on the wall forming the lumen. The monitoring device comprises a sensor element configured to detect a physical event and to generate an electrical parameter shift in response to the physical event. An antenna portion is configured to receive a first oscillating electrical signal from an interrogator device and to transmit a second oscillating electrical signal to the interrogator device. The second oscillating electrical signal is modulated by the electrical parameter shift.Type: GrantFiled: July 12, 2017Date of Patent: May 18, 2021Assignee: Graftworx, Inc.Inventors: David Kuraguntla, Samit Kumar Gupta, Lilip Lau, Anthony F.
