Publication number: 20100278627Abstract: The disclosure relates to a cassette, frame and mold for holding a tissue sample during an embedding and mircotoming process, and related methods. The cassette is sectionable in a microtome and includes a body with a bottom wall and a plurality of side walls. First and second side walls are generally V-shaped to present an apex of the āVā to the microtome blade. A lid of the cassette is stiffer than the bottom wall of the cassette to assist with positioning the tissue sample. The side walls of the cassette are perforated so as to significantly reduce the amount of cassette material that must be cut by the microtome blade. In one embodiment, to additionally reduce blade wear the ribs on one side wall are offset lengthwise relative to the ribs on an opposite side wall. An upper flange of the cassette includes depressions configured to register with detents in the frame.Type: ApplicationFiled: July 14, 2010Publication date: November 4, 2010Applicant: BIOPATH AUTOMATION, L.L.C.Inventors: Warren P. Williamson, IV, Craig B. Berky, Stephen P. Whitlatch, Thomas J. Ward

Patent number: 7722642Abstract: Wire fasteners having legs with lengths that can be one hundred times the width of the fastener are used to secure items, such as prosthesis valves to a patient during minimally invasive surgery. The fasteners are manipulated into position and then are immobilized by means of the legs thereof for tensioning, cutting and forming in situ. The fasteners are manipulated, tensioned and formed from the leg end of the fasteners. Tools for initially placing the fasteners and for immobilizing, tensioning, cutting and bending the fastener legs are disclosed. Once the fasteners are initially placed, the prosthesis is placed on the long legs of the placed fasteners and is guided into position on the legs. Once the prosthesis is in position, the legs of the fasteners are immobilized, tensioned, cut and bent into staple-like shapes to secure the prosthesis to the patient. A method for carrying out the procedure using the long fastener is also disclosed.Type: GrantFiled: February 25, 2004Date of Patent: May 25, 2010Assignee: Medtronic, Inc.Inventors: Warren P.

Publication number: 20090247117Abstract: A cellular telephone system has call management decisions made based on the exact geographic location of the mobile unit. These call management decisions include billing and taxing decisions, cell site selection, frequency selection and even cellular system selection. The decisions are continuously updated during a call whereby decisions can be made and changed regardless of where a call originated. Cell site location, and even cellular system selection, can be made in a specific manner to best serve the needs of the mobile user, the cellular system as well as the public. It is even possible for a cellular system to locate one or more of its cell sites in the geographic area served by another cellular system. In some cases, cellular systems might even share cell sites.Type: ApplicationFiled: June 11, 2009Publication date: October 1, 2009Applicant: EMSAT ADVANCED GEO-LOCATION TECHNOLOGY, LLCInventors: Everett Dennison, Timothy J.

Patent number: 7497865Abstract: A ring for use in anastomosis. Preferably, the ring is integrally formed from metal, and includes a ring portion and tines and docking members that extend from the ring portion. The ring portion and tines are malleable, and preferably also the docking members are malleable. The ring portion and tines are malleable in the sense that once deformed from a first shape into a second shape, they will not relax back into the first shape from the second. To install the ring in a vessel with the ring portion extending around an incision or other orifice, the tines pierce the tissue around the orifice and are curled against an anvil. The action of curling the tines inverts the tissue near the orifice edges to expose the inside surface of the vessel or organ.Type: GrantFiled: May 26, 2004Date of Patent: March 3, 2009Assignee: MAQUET Cardiovascular, LLCInventors: Geoffrey H. Willis, Thomas A. Kramer, Paul A. Spence, George T. Christakis, Timothy J. McCoy, John W. Davis, Bradley D. Blackwood, Peter Callas, Michael Francis Wei, Jonathan L. Podmore, Andrew Knight, Thomas J.
