Patent number: 11844504Abstract: 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.

Publication number: 20230038323Abstract: 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.Type: ApplicationFiled: June 15, 2022Publication date: February 9, 2023Inventors: Christopher REAH, Jonathan ARCOS, Nicholas SANDHAM, David POWELL, John SUTCLIFFE, Patrick MCKENNA

Publication number: 20220015921Abstract: 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.Type: ApplicationFiled: November 19, 2019Publication date: January 20, 2022Inventors: Christopher REAH, Jonathan ARCOS, Nicholas SANDHAM, David POWELL, John SUTCLIFFE, Patrick MCKENNA

Publication number: 20220015920Abstract: 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.Type: ApplicationFiled: November 19, 2019Publication date: January 20, 2022Inventors: Christopher REAH, Jonathan ARCOS, Nicholas SANDHAM, David POWELL, John SUTCLIFFE, Patrick MCKENNA
