Abstract: A method for processing a dual phase steel sheet. The method includes heating the steel sheet to a first temperature (T1), cooling the steel sheet to a second temperature (T2), transitioning the steel sheet to a third temperature (T3), and cooling the steel sheet to room temperature. T1 is at least above the temperature at which the steel sheet transforms to austenite and ferrite. T2 is below the martensite start temperature (Ms). The cooling rate to T2 is sufficiently rapid to transform at least some austenite to martensite.

Abstract: A housing for an antenna has an end member having a radome seat and a back extension. The end member also has at least one actuator housing with an external opening and an internal opening. The end member has no through passage from its external side to its internal side, other than the opening of the actuator housing, such that upon assembly with a back and a radome, the antenna is water-tight. A retention assembly has an internal retaining member and an internal retaining member receiver. An actuator has an external actuation interface, and is mounted in the actuator housing to be water-tight. The retention assembly has a first position and a second position. The first position engages the internal retaining member with the internal retention receiver such as to maintain a closed water-tight engagement with the back and the radome. The retention assembly has a second, released position, that allows disengagement of the end member from a reflector tray.

Abstract: A method and instrumentation particularly adapted for disc space preparation from an anterior approach to the spine. In one aspect, an expandable template is provided having guides to guide a cutting device for bilateral formation of openings in the disc space. In another aspect, an improved guide member is provided for guiding a cutting tool. Still further, the invention provides an improved double barrel guide sleeve with a central distraction extension and lateral non-distracting extensions. Optionally, the guide sleeve includes windows and covers to selectively cover the windows. An improved reamer with an internal chamber and optional modular coupling is also provided. A depth stop is provided to selectively engage a tool shaft and a guide sleeve to control tool penetration into the disc space. A method of using the disclosed instruments is also provided.

Abstract: An antenna comprising a reflective surface; and an array of dipole antenna elements disposed adjacent to the reflective surface. Each antenna element has a pair of arms which together define a dipole axis, and the dipole axis is tilted at an acute angle with respect to the reflective surface. The pair of arms may be dipole arms, or may be Yagi director arms. In some embodiments the dipole axis is tilted at an acute angle with respect to a feed axis. In some embodiments the antenna element comprises a feed portion defining a feed axis; and the feed portion has a mounting portion which is tilted at an acute angle with respect to the feed axis.

Abstract: This invention relates to a porous bone implant (10, 110, and 210), a method of manufacturing the implant and a method of orthopedic treatment. The mesh implant can be manufactured using extrusion techniques and a variety of cutting and machining processes to provide the implant with the desired structural features and in the required dimensions to be matingly received within the bone defect or cavity. The implant can be used to strengthen bone structures and support bone tissue adjacent to a defect of cavity. Thus, the implant can be used to provide improved treatment of patients having bone defects or diseases with decreased postoperative pain and a shorter recovery time.

Abstract: An interbody fusion device in one embodiment includes a tapered body defining a hollow interior or chamber for receiving bone graft or bone substitute material. The body defines exterior threads which are interrupted over portions of the outer surface of the device. The fusion device includes truncated side walls so that on end view the body takes on a cylindrical form. In another embodiment, the tapered body is solid and formed of a porous biocompatible material having sufficient structural integrity to maintain the intradiscal space and normal curvature. The material is preferably a porous tantalum composite having fully interconnected pores to facilitate complete bone tissue ingrowth into the implant. In further embodiments, the fusion devices are provided with osteogenic material to facilitate bone ingrowth. A cap is also provided to block the opening of hollow fusion devices. The cap includes an occlusion body and an elongated anchor.

Abstract: The present invention provides an implant for use in fusing adjacent bony structures. The implant comprises at least one structural member combined with at least one flexible planar member to retain the at least one structural member to form the implant.

Abstract: A laparoscopic surgical technique is provided for preparing a site for implantation of a fusion device or implant. In accordance with one embodiment of the technique, a laparoscope is provided having an outer sleeve with distraction fingers at one end to distract the disc space. The laparoscope includes a laparoscopic port at its opposite end through which instruments and implants are inserted. The laparoscope provides a sealed working channel to the disc space, through which the disc space is distracted, the vertebral endplates and surrounding disc is reamed, and the fusion device inserted. The laparoscope is alternately engaged within bilateral locations in the disc space for insertion of a pair of fusion implants. A switching sleeve extends through the laparoscope to protect the tissue at the surgical site as the laparoscope is moved between the bilateral fusion locations.
