Publication number: 20130224866Abstract: A medical device, such as a vascular access device, is disclosed for providing access to a medical fluid flow path for the introduction or withdrawal of medical fluids to and from the flow path. The access device includes an indicator for providing a visual indication when the access device has been exposed to an antiseptic agent. The indicator includes a substrate and a microporous layer disposed on the substrate. The microporous layer is made from a polymer material having an index of refraction from about 1.25 to about 1.6 and is configured to change from a substantially opaque state to a substantially transparent state upon exposure to an antiseptic solution. The microporous layer resumes the substantially opaque state after a period of time.Type: ApplicationFiled: April 18, 2013Publication date: August 29, 2013Applicants: Baxter International Inc.Inventors: Baxter International Inc., Baxter Healthcare S.A.

Patent number: 8517835Abstract: A video game controller with a position sensor and a proximity sensor provides user input signals for use in determining game states. The video game controller can have a board or deck like surface similar to that of a skateboard, and the proximity sensor can be used to determine if a grab of the board has been attempted. A video game associated with the video game controller can provide a skateboard or other game in which a skateboard and skateboarding character are responsive to a game player's manipulation of the video game controller.Type: GrantFiled: February 20, 2009Date of Patent: August 27, 2013Assignee: Activision Publishing, Inc.Inventors: Patrick Dwyer, Nick Ehrlich, Matt Knowles, Scott Krager, Arnab Sen, David M. Tibbetts, Joshua Tsui, Peter J. Sauerbrei

Patent number: 8497080Abstract: The method of the invention pertains to determining signal transduction activity in a tissue section by immunohistochemistry techniques. The expression level of the receptor of interest is determined as well as the expression levels of one or more effector molecules of the receptor signal transduction pathway. Furthermore a combined ratio of expression levels of effector molecules in subcellular compartments with the receptor expression was found to have prognostic significance.Type: GrantFiled: February 5, 2013Date of Patent: July 30, 2013Assignees: HistoRx, Inc., Yale UniversityInventors: Mark Gustavson, Jennifer Giltnane, Marisa P.

Patent number: 8470601Abstract: An apparatus for indicating biological content within a container is provided. The apparatus includes a medical sterilization container having a cover removably attached to the medical sterilization container. An enclosable, sterilizable interior compartment is formed by the medical sterilization container and the cover, wherein the interior compartment is sized to house at least one medical instrument. A biological indicator is located at least partially in communication with the interior compartment, wherein the biological indicator provides at least one indication of biological content within the interior compartment after the medical sterilization container and cover are subjected to a sterilization process.Type: GrantFiled: November 16, 2011Date of Patent: June 25, 2013Assignee: Symmetry Medical Manufacturing, Inc.Inventors: Tony Foley, Gary T.
