  • Publication number: 20110130678
    Abstract: A unitary shave biopsy blade comprises a first side edge, a second side edge laterally spaced from the first side edge, and a front edge extending laterally between the first and second side edges. A back edge extends laterally between the first and second side edges and is spaced longitudinally from the front edge. At least one of the front and back edges is at least partially sharpened to form a cutting edge. A top surface is defined laterally between the first and second side edges and longitudinally between the front and back edges. A bottom surface is defined laterally between the first and second side edges and longitudinally between the front and back edges and is spaced from the top surface by a blade thickness. At least one of the top and bottom surfaces includes a bend area feature which defines a local reduction in the blade thickness. A method of excising a target area from a surface of a skin tissue is also disclosed.

  • Publication number: 20100278627
    Abstract: 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 ā€œVā€ 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.

  • Patent number: 7722642
    Abstract: 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.

  • Patent number: 7708759
    Abstract: 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.

  • Publication number: 20090247117
    Abstract: 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.
