Patent number: 11904130Abstract: Fluid access devices include a machine-side hydraulic circuit and a patient-side hydraulic circuit, and are configurable between a connected state and at least one disconnected state. In the connected state, fluid flows between the machine-side hydraulic circuit and the patient-side hydraulic circuit. In the disconnected state, fluid does not flow between the machine-side hydraulic circuit and the patient-side hydraulic circuit. In some disconnected states, fluid recirculates through at least one of the machine-side hydraulic circuit or the patient-side hydraulic circuit in the disconnected state.Type: GrantFiled: March 21, 2022Date of Patent: February 20, 2024Assignee: University of WashingtonInventors: Barry Fulkerson, Jeremy Barribeau, Anna Galperin

Patent number: 11701459Abstract: Methods, systems, and kits are provided for performing hemodialysis, hemodiafiltration, and peritoneal dialysis on a portable machine suitable for both clinical and home use. Peritoneal dialysate can be flowed into and out of the peritoneal cavity, and can also be regenerated within the system, without the need for introducing fresh dialysate. Common hardware and software can be utilized for both peritoneal dialysis and other forms of dialysis such as hemodialysis, hemofiltration, and hemodiafiltration, allowing for facile transition between different dialysis modes using the same dialysis machine.Type: GrantFiled: January 2, 2020Date of Patent: July 18, 2023Assignee: FRESENIUS MEDICAL CARE HOLDINGS, INC.Inventors: Palmer David Updyke, Barry Fulkerson, Amaury De Leon De Leon, Michelle Bayly

Publication number: 20060084906Abstract: A flow management system comprising a first panel having a fluid pathway and a second panel having a fluid pathway for passing a second fluid. The fluid pathway of the first panel passes a first fluid. The first panel includes a first compartment to receive a volume of the first fluid. The second panel includes a second compartment to receive a volume of the second fluid. The first and second panels are aligned so that the first compartment overlays the second compartment. The flow management system may be placed within a gap defined by a first surface and a second surface. The first and second compartments are disposed within the gap so that the second compartment bears against the second surface as the second fluid fills the second compartment and forces the first fluid out from the first compartment as the first compartment bears against the first surface.Type: ApplicationFiled: October 31, 2005Publication date: April 20, 2006Applicant: NXSTAGE MEDICAL, INC.Inventors: Jeffrey BURBANK, James BRUGGER, Dennis TREU, C.
