Patent number: 11969329Abstract: A “dry” packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.Type: GrantFiled: May 3, 2022Date of Patent: April 30, 2024Assignee: MEDTRONIC VASCULAR, INC.Inventors: Raymond Ryan, David Clarke, Kshitija Garde, Ya Guo, Benjamin Wong, Yogesh Darekar, Luke Lehmann, Wei Wang, Laura McKinley, Paul Devereux, Joshua Dudney, Tracey Tien, Karl Olney

Patent number: 11365045Abstract: Packaging of fruits in containers. The containers preferably have designed permeabilities to oxygen, carbon dioxide, and ethylene and include a gas-permeable membrane comprising (1) a microporous film, and (2) a polymeric coating on the microporous film. The containers enable storage and/or ripening of fruits under controlled conditions. Using the new containers, fruits can be ripened while they are being transported, or in conventional ripening rooms without opening the bags in which they have been transported. In addition, fruits can be preserved in a satisfactory ripened state for longer periods of time. Methods of treating fruits with insecticides, fungicides and mold-inhibiting compounds are also disclosed.Type: GrantFiled: September 8, 2014Date of Patent: June 21, 2022Assignee: Curation Foods, Inc.Inventor: Raymond Clarke

Publication number: 20170000142Abstract: Atmosphere control members (ACMs) are used in various ways. In one aspect, at least one of the atmospheres in contact with the ACM is caused to flow over the surface of the ACM. In another aspect, the ACM is an internal ACM which does not form part of the exterior surface of a container. In another aspect, the ACM forms part of a reusable module. In another aspect, a plurality of sealed containers, each including an ACM, are stored in an outer container also including an ACM. FIGS. 3-5 illustrate a shipping container 11 comprising an internal ACM having one surface which is exposed to the packaging atmosphere within the shipping container and an opposite surface which is part of a closed chamber 2 to which gases can be supplied in a controlled fashion.Type: ApplicationFiled: May 18, 2015Publication date: January 5, 2017Inventors: Raymond Clarke, Nicholas J Tompkins

Patent number: 9185920Abstract: Packaging of respiring biological materials, particularly bananas and other fruits, in sealed containers. The containers preferably include a gas-permeable membrane comprising (1) a microporous film, and (2) a polymeric coating on the microporous film. Using appropriate containers and appropriate controlled atmospheres around the container, the respiring materials can be stored and/or ripened under controlled conditions. Bananas can be ripened while they are being transported, or in conventional ripening rooms without opening the containers in which they have been transported. The ripe bananas are less dehydrated and remain in a satisfactory ripened state for longer periods of time. The gas-permeable membrane can preferably take the form of either a “curtain” or “cartridge” and the R ratio of the membrane may be optimized by adjusting the differential pressure across the membrane.Type: GrantFiled: January 23, 2013Date of Patent: November 17, 2015Assignee: Apio, Inc.Inventors: Raymond Clarke, Angel Reyes

Patent number: 9034405Abstract: Combinations of atmosphere control members are used to control the atmosphere within a sealed container which contains a respiring biological material. The combination makes use of a first ACM having a first R ratio (the ratio of carbon dioxide permeability to oxygen permeability) and a second ACM having a second R ratio, the first R ratio being substantially greater than 1.0, and the second R ratio being less than the first R ratio. This combination (31, 321, 322, 331, 332) can form part of the sealed container (1) itself, or can be part of an assembly (31, 32, 34) through which the packaging atmosphere within the sealed container (1) is circulated.Type: GrantFiled: July 28, 2006Date of Patent: May 19, 2015Assignee: Apio, Inc.Inventor: Raymond Clarke

Patent number: 7603242Abstract: A method of detecting a fuel leak from a fuel store of an aircraft where a processor receives inputs relating to the amount of fuel in the fuel store and to the rate of fuel used by the aircraft. The processor defines a fuel flow system state defined by a noise-compensated measures of the amount of fuel in the fuel store, a fuel leak amount estimate and a fuel leak rate estimate. The processor periodically calculates a new estimated state of the system in view of a previous estimated state and values of the inputs. The processor monitors the fuel leak amount estimate and the fuel leak rate estimate and if either exceeds a respective threshold value send a signal to a fuel leak warning device.Type: GrantFiled: September 21, 2005Date of Patent: October 13, 2009Assignee: Airbus UK LimitedInventors: Franklin George Tichborne, Raymond Clarke, Michael Daniel Brown

Publication number: 20080103703Abstract: A method of detecting a fuel leak from a fuel store of an aircraft is described. In the described embodiment, a processor (1) receives inputs (2, 3) relating to the amount of fuel in the fuel store and to the rate of fuel used by the aircraft, both inputs being subject to noise. The processor defines a fuel flow system state defined by a noise-compensated measures of the amount of fuel in the fuel store, a fuel leak amount estimate and a fuel leak rate estimate. The processor (1) periodically calculates a new estimated state of the system in view of a previous estimated state of the system and values of the inputs (2, 3). The processor monitors the fuel leak amount estimate and the fuel leak rate estimate and if either exceeds a respective threshold value send a signal to a fuel leak warning means (4). The method employed in the embodiment employs a recursive state estimation method that improves leak detection, reduces false alarms and is less demanding on processor and memory requirements.Type: ApplicationFiled: September 21, 2005Publication date: May 1, 2008Inventors: Franklin George Tichborne, Raymond Clarke, Michael Daniel Brown

Publication number: 20080058180Abstract: An exercise tube and handle attachment incorporates an elastic tube having a handle(s) fabricated from a strong material such as nylon strapping. The handle is configured, by stitching, to form a passageway and compartment for receiving an end of the exercise tube. A knot is made in the end of the tube to prevent the end from exiting the compartment and separating the tube from the handle.Type: ApplicationFiled: July 10, 2006Publication date: March 6, 2008Inventors: Raymond Clarke, Lorri Wilson-Clarke
