    Abstract: A determination oxygen storage amount used to determine whether a catalyst is degraded is a value obtained by applying a correction amount for removing error caused by response delay time of an output signal of an oxygen sensor to an oxygen storage amount calculated every short time. The correction amount is a value that is calculated using slopes stored in memory, i.e., the slopes for the number of storage cycles (>the short time) corresponding to the response delay time, or the like, and becomes more accurate as a value corresponding to the error as the storage cycle becomes relatively shorter with respect to the response delay time and the number of the slopes stored in the memory increases. The necessary storage capacity of the memory is inhibited from increasing excessively even if the number of the slopes stored in the memory is large.

  • Patent number: 8133263
    Abstract: A connector for a spinal alignment system includes a base, a hook, a guide aperture, and a locking portion. The base includes a channel extending therethrough to receive a fixation rod. The hook extends from the base. The guide aperture is adapted to receive a bone fastener and the locking portion is adapted to engage the bone fastener. The guide aperture extends through one of the base and the hook and the locking portion is located in the other of the base and the hook. The locking portion is coaxial with the guide aperture such that the guide aperture guides a shaft of the bone fastener into alignment with the locking portion when the bone fastener is received by the guide aperture. The bone fastener cooperates with the base and hook to form a tension band construct that resists opposing forces acting on the construct. A rod locking fastener engages the channel and the fixation rod to secure the fixation rod in the channel.

  • Patent number: 7959655
    Abstract: The present application is directed to a device for connecting an elongated member within a patient. The device includes a body with a receiving section to receive the elongated member, and an engagement section to engage a support structure, such as a vertebral member. The receiving section is sized to receive the elongated member in a first orientation. The process of securing the elongated member within the receiving section causes the device to pivot about the elongated member to a second orientation. This pivoting motion causes the engagement section to more securely attach to the support structure.

  • Patent number: 7918876
    Abstract: An adjustable spinal implant (10) is provided for use in connecting elongate members (12) as well as vertebral spacers such as corpectomy devices, intervertebral fusion devices, and other prostheses. The implant (10) may have fittings (80) on either end comprising fixed (100) or articulating (200) jaws, endplates, or other engagement structures. The implant (10) comprises a housing (40) with an internal rotor (60); an extending shaft (20); and a locking collar (70). The extending shaft (20) has an external helical groove (23) that meshes with an internal helical groove (63) on rotor (20). Length adjustment occurs by transforming axial movement of the extending shaft (20) into a rotary movement of the rotor (60) via helical engagement. The locking collar (70) comprises protrusion (73) engaging grooves (63) of rotor (60), thus providing a simple, positive locking mechanism without requiring the surgeon to apply excessive force to lock the length.
