Abstract: An intervertebral fusion device comprises an endplate, a core component and at least one ratchet. Each of the endplate and the core component has a leading end and a trailing end and is configured to be received in an intervertebral space defined between first and second vertebrae. The ratchet comprises a pawl and a linear rack defining plural recesses. The pawl is comprised in the core component or the endplate and the linear rack is comprised in the other of the core component and the endplate. The core component and the endplate are configured to engage with each other by disposing the leading end of the core component adjacent the trailing end of the endplate and then moving the core component relative to the endplate in a direction of insertion such that the leading end of the core component moves towards the leading end of the endplate and extent of overlap of the core component and the endplate increases.

Abstract: A self-supporting surgical retractor is provided for retracting soft tissue and anatomy at a spinal surgical site. The retractor includes a tubular base defining an upper rim and a lower rim and a working channel there between the upper and lower rims, in which the base and lower rim are sized and configured to be seated on adjacent vertebral bodies spanning an intervertebral space. At least two elongated legs are provided, each projecting from the upper rim and each including a fixation feature at a free end thereof. Each of the legs has a length sufficient for the fixation feature to be outside the body of a patient when the lower rim is seated on adjacent vertebral bodies of the patient. The retractor is formed of a radio-transparent or radio-lucent material.

Abstract: A kit of parts from which selection is made to form an intervertebral fusion device. The kit of parts comprises a plurality of different endplates and a core component. Each of the plurality of different endplates is configured to be received in an intervertebral space defined between first and second vertebrae. The core component is configured to engage with each of the plurality of endplates and a selected one of the plurality of endplates when the selected endplate and the core component are received in the intervertebral space. Each of the plurality of endplates defines a bone graft aperture which is open at top and bottom surfaces of the endplate and extends between the top and bottom surfaces, the thus defined bone graft apertures being of substantially the same dimensions as one another when the plurality of endplates are in plan view.

Abstract: The present invention relates to an intervertebral fusion device 10 comprising a superior component 12, an inferior component 14 and a core component 16. The superior component 12 and the inferior component 14 are receivable in an intervertebral space between first and second vertebrae with the core component 16 insertable between the superior and inferior components to determine a separation between the superior and inferior components. A bone graft conveying aperture is defined in at least one of a superior component top surface 18 of the superior component and an inferior component bottom surface 20 of the inferior component. The core component defines a bone graft material holding space which is enclosed except at at least one of a core component top surface and core component bottom surface of the core component and a bone graft material delivery opening. The bone graft material delivery opening extends from outside the core component side to the bone graft material holding space.

Abstract: The present invention relates to an intervertebral fusion device (10) comprising a superior component (20), an inferior component (40) receivable in an intervertebral space between first and second vertebrae, with the core component (80) insertable between the superior and inferior components to determine a separation between the superior and inferior components. The superior, inferior components and core components comprise respective formations and profiles. The formations (54, 68) present a barrier to separation of the core from one of the inferior and superior components during insertion of the core component. The profiles guide the core component during insertion of the core component while presenting no barrier to separation from each other during its insertion. The components comprise further formations (39, 76) which present a barrier to separation of the components from each other once the core has been fully inserted between the inferior and superior components.

Abstract: An intervertebral fusion device comprises a superior component, an inferior component, and a core component. The superior and inferior components are received between first and second vertebrae whereby a superior component top side of the superior component abuts against the first vertebra, and an inferior component bottom side of the inferior component abuts against the second vertebra. The core component is inserted between the superior and inferior components to determine a height of the intervertebral fusion device. First and second core profiles of the core component cooperate respectively with a first component profile of the superior component and a second component profile of the inferior component during insertion of the core component to guide the core component relative to the superior and inferior components.

Abstract: A coating composition that can be used in a process for coating a substrate where in a first step a radiation curable coating composition is applied to the substrate and/or a radiation permeable film. Next, the substrate and the film are pressed together in such a way that the coating composition is sandwiched between them. Thereafter, the coating composition is cured by irradiation through the film to obtain a coated substrate. In a subsequent step, the film is removed from the coated substrate. The coating composition applied to the film and/or the substrate is a hot melt composition comprising 20 to 100 wt. % of a radiation curable resin or mixture of radiation curable resins having a viscosity in the range of from 15 to 10,000 mPa.s in the temperature range of from 40 to 150° C.

Abstract: A spinal implant for engagement in a space between upper and lower vertebrae has a center part extending along an axis and formed with upper and lower screwthreads of opposite hand. Respective upper and lower end parts axially flank the center part and each have an inner end threaded onto a respective one of the screwthreads and an outer end adapted to bear on a respective one of the vertebrae. One of the end parts is formed with an eye having a hole open transversely of the axis. A screw engages through the hole and anchors the one end part to the respective vertebra. The other end part is also formed with an eye having a hole open transversely of the axis and another screw engages through this hole and anchors the other end part to the respective vertebra.

Abstract: An enterprise business planning system includes a server to an application server to execute an enterprise planning activity in accordance with a model that defines a set of enterprise users. The system further includes an extension manager to selectively deploy software extensions to the enterprise users in accordance with the model. The model may, for example, define roles for the enterprise users, and the extension manager selectively deploys the software extensions to the enterprise users based on the roles assigned to the enterprise users. As another example, enterprise model may comprises a multi-level hierarchy of related nodes, and associates the enterprise users with the nodes. The extension manager may selectively deploy the software extensions to the enterprise users based on the levels of respective nodes associated with the enterprise users.
