Patent number: 6852289Abstract: Methods and apparatus for qualitatively or quantitatively determining one or more analytes in matrices such as foods, biological fluids, etc. An embodiment for determination of a single analyte comprises a sample receiving vessel, a first membrane and a reagent-containing well. The prepared sample passes through the first membrane whereby extraneous matter is removed, and a filtrate enters the reagent-containing well to provide a filtrate-reagent admixture from which the analyte may be determined. An embodiment for determination for multiple analytes includes one or more additional membranes in series with the first membrane, each such additional membrane being operative to capture one or more analytes. Each of the additional analytes may then be eluted from the membrane upon which it has been captured, into a separate reagent-containing well to provide eluant-reagent admixture from which each desired analyte may be determined. Formulations for preparation additives are also included.Type: GrantFiled: March 26, 2001Date of Patent: February 8, 2005Assignee: Saftest, Inc.Inventors: Virginia C. Gordon, Bennett W.

Patent number: 6820490Abstract: Methods and systems for measuring the pressure of a fluid. A flexible barrier separates the fluid from the pressure receiving surface of a pressure sensing device. The pressure of the fluid is transferred through the flexible barrier to the pressure receiving surface. The flexible barrier may be in abutting juxtaposition with or may be spaced apart from the pressure sensing surface. In either case, the flexible barrier is coupled or held in defined relationship to the pressure sensing surface such that the pressure receiving surface will receive the substantially actual pressure of the fluid even when the pressure of the fluid is less than the ambient atmospheric pressure. Coupling of the flexible barrier to the pressure receiving surface may be achieved by any suitable means, including adhesive or the application of a full or partial vacuum between the flexible barrier and the pressure receiving surface.Type: GrantFiled: October 16, 2002Date of Patent: November 23, 2004Assignee: Neomedix CorporationInventors: Michael Mittelstein, John T.

Patent number: 6655934Abstract: Inverted peristaltic pumps and related apparatus/methods wherein one or more compressible pump tubes are formed or mounted on a core member and one or more tube compressing members move about the core member so as to compress the tube(s) and propel a fluid through the tube(s). The core member may be removable and the pump tube(s) may be pre-mounted on the core member to form a disposable or reusable tubing cartridge. The core member or tubing cartridge may be easily inserted into and removed from the pump. In some embodiments troughs or grooves may be formed on the core member and the tube(s) may be disposed in such troughs or grooves.Type: GrantFiled: March 20, 2002Date of Patent: December 2, 2003Assignee: Innovent, L.L.C.Inventors: Michael Mittelstein, John T.

Patent number: 6506176Abstract: A system for removing the lens from an eye of a mammal, including a lens-removal device having a probe for penetrating the lens capsule. The probe includes a sheath that shields a rotating impeller at all times, with the impeller being pneumatically actuated to advance to a lens removal position within the sheath. The impeller is pneumatically rotated using a turbine mechanism within a handle for the probe. Irrigation and aspiration are provided to facilitate removal of the lens tissue. The turbine is driven with pulsed air to prevent stiction. A purge/protection cap helps remove air bubbles from the system prior to use and protects the delicate impeller during transport. An operating system is also provided with a foot pedal actuator.Type: GrantFiled: February 16, 2000Date of Patent: January 14, 2003Assignee: Bausch & Lomb IncorporatedInventors: Michael Mittelstein, John T.
