Patent number: 7776274Abstract: 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: GrantFiled: March 4, 2005Date of Patent: August 17, 2010Assignee: 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.

Patent number: 7708759Abstract: Apparatus and methods for repairing damaged tendons or ligaments. Various repair apparatus include an elongate tensile member and a pair of anchor structures connected for movement along the tensile member on either side of a repair site, such as a tear or laceration. The anchor structures may take many forms, and may include barbed, helical, and crimp-type anchors. In the preferred embodiments, at least one anchor structure is movable along the elongate tensile member to assist with adjusting a tendon segment to an appropriate repair position and the anchor structure or structures are then lockable onto the elongate tensile member to assist with affixing the tendon at the repair position. Tendon-to-bone repair apparatus and methods are also disclosed employing similar concepts. Tendon retrieval devices include helical members for rotating into a tendon end and subsequently moving the tendon to an appropriate operating position.Type: GrantFiled: July 16, 2003Date of Patent: May 4, 2010Assignee: Tendon Technology, Ltd.Inventors: Lawrence M.

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.

Patent number: 6884251Abstract: An anastomosis is performed using a flexible mounting structure mounted on the outside of at least one vessel. Fasteners extend through the vessel and are bent towards the incision to attach the flexible mounting structure to the vessel in a manner that controls the edge of the vessel adjacent to the incision. The mounting structures are oriented on each vessel so fasteners on one mounting structure interdigitate with fasteners on the other mounting structure at the location of contact between the vessels when the two vessels are brought together. This creates two complementary sinusoidal-shaped vessel edges with peaks of one edge being accommodated in the valleys of the other edge. The peak-to-valley orientation forms a sinusoidal-shaped joint which is leak free. The fasteners are spaced so proper pressure is applied to the tissue to promote healing without leaking. Furthermore, the fasteners are sized and shaped to properly engage the tissue and bend in a desired manner.Type: GrantFiled: March 6, 2003Date of Patent: April 26, 2005Assignee: Origin Medsystems, Inc.Inventors: Paul A. Spence, Warren P. Williamson, IV, George Christakis, Mark Ortiz, Craig B. Berky, Douglas P. Allen, Matthew J. Huddleston, Delbert Ted Leimbach, Cecil R. Robinson, E. Dale VanHoose, Thomas J.
