Patent number: 10076643Abstract: A gravitational pressure regulating valve to regulate fluid flow of a patient, including a fluid chamber having an inlet port to receive a bodily fluid and an outlet port to discharge received bodily fluid, the fluid chamber including a first chamber configured to capture a non-buoyant member therein and to guide the non-buoyant member along a longitudinal axis of the first chamber to facilitate bi-directional reciprocating movement of the non-buoyant member to and from the inlet port, and a second chamber configured to capture one or more buoyant members therein such that when the second chamber is filled with bodily fluid, at least one of the buoyant members applies a resolved buoyant pressure from a buoyant force of the one or more buoyant members in opposition to an inlet pressure of fluid at the inlet port.Type: GrantFiled: December 9, 2015Date of Patent: September 18, 2018Assignee: Arkis Biosciences Inc.Inventors: Chad Seaver, Chris Arnott, James Alexander Killeffer

Publication number: 20150265171Abstract: A bio-pressure sensor system is disclosed, comprising a first sensor configured to provide a reference pressure measurement and second sensor configured to measure a fluid pressure within a human body. The bio-pressure sensor system also comprises a first reference element and second reference element. The first and second sensors share the first reference element. The second reference element is coupled to the first sensor and configured to provide a reference pressure. The first and second sensors each comprise independent output signals.Type: ApplicationFiled: March 24, 2015Publication date: September 24, 2015Inventors: Chad Eric Seaver, James Chris Arnott, James Alexander Killeffer
