Patent number: 9669404Abstract: A valve assembly for use with a flexible container, in which the valve assembly is anchored to the flexible container. The valve assembly provides for the egress of fluid from the flexible container such that the interior surfaces flexible container do not block or otherwise prevent fluid flow or fluidic communication between the interior of the flexible container and the valve assembly. The portion of the valve assembly within the interior of the flexible container includes a support structure that prevents the walls of the flexible container from collapsing down on, and blocking either completely or in part, fluid flow through the opening of the valve inside of the flexible container.Type: GrantFiled: May 19, 2016Date of Patent: June 6, 2017Assignee: Bio-Rad Laboratories, Inc.Inventors: Luis Ortiz-Hernandez, Kenneth Davenport

Patent number: 8623060Abstract: A small cannulated bone screw is provided having an optimized combination of strength, cannula size and thread depth. A set of such strong and small size screws is also provided where the smallest sizes can have one performance ratio emphasized over another, and the larger sizes can have the emphasis reversed. In particular, the smallest screws optimize the combination of their strength and cannula size with the larger screws optimizing the combination of their strength and thread depth. In any event, each of the screws in the set has an optimized combination of strength, cannula size and thread depth throughout the full range of screw sizes in the set, e.g. 3.0 mm to 7.5 mm major diameters.Type: GrantFiled: March 26, 2007Date of Patent: January 7, 2014Assignee: Pioneer Surgical Technology, Inc.Inventors: Jeff Vlahos, Matthew N. Songer, Kenneth Davenport

Publication number: 20080045925Abstract: System for the delivery of drugs from sealed cartridges provide for versatile and convenient delivery of the drugs. The system can be designed to deliver drugs from a plurality of cartridges with delivery through a manifold that connects to the plurality of cartridges. In some embodiments, the system mediates the heating of the drug such that it can be delivered at a temperature more closely approximating body temperature. In some embodiments, the composition of one cartridge is used to adjust the pH of the composition of the resulting mixture to achieve a desirable blended drug. The systems and procedures are particularly advantageous for the delivery of dental anesthetics.Type: ApplicationFiled: June 18, 2007Publication date: February 21, 2008Inventors: Matthew Stepovich, Michael Falkel, Kenneth Davenport

Patent number: 6123708Abstract: A nail (or rod) for axial insertion into a large bone for support thereof, which comprises an elongated nail body having a central bore extending through the nail body from the proximal end along a proximal portion of the nail, and typically terminating at point spaced between the ends. The nail may also define a transversely flattened distal portion extending proximally from the distal end. In the embodiment shown, an open slot may extend centrally and longitudinally from the distal end along the distal portion to an inner slot end which is spaced between the ends of the nail. The nail body defines a plurality of transverse holes extending therethrough for receiving bone screws for supporting securance of the nail to a bone while the nail occupies the intramedullar space of the bone.Type: GrantFiled: February 3, 1999Date of Patent: September 26, 2000Assignee: Pioneer Laboratories, Inc.Inventors: Thomas N. Kilpela, Clayton R. Perry, Kenneth A. Davenport, Matthew N. Songer
