Abstract: An expandable interbody device for placement between adjacent vertebrae having an upper structure, a lower structure and a screw mechanism, wherein actuation of the screw mechanism moves the upper and lower structures between a collapsed configuration and an expanded configuration. A deployment tool couples to the expandable interbody device for positioning the device between adjacent vertebrae, actuating the screw mechanism and delivering a material to a chamber of the expandable interbody device.

Abstract: A spinal implant device is provided comprising a body structure with a central cavity and a movable lid configured to cover the central cavity. The movable lid is configured to be opened to pack a material in the central cavity. The movable lid can be connected to the body structure with a moveable joint. The spinal implant device can include a compressible feature. A method for treating the spine is provided comprising opening a movable lid of a spinal implant device, packing a material in a central cavity of a spinal implant device, closing the movable lid, and inserting the spinal implant device between vertebrae.

Abstract: An orthopedic fixation device operable for securing bone parts comprising one or more blocking cams integrated into a structural support device such as an intervertebral spacer or a fixation plate. The blocking cam is irremovable from the structural support device without destruction of the blocking cam or the structural support device or both. In preferred embodiments, the blocking cam comprises a central body with one or more tabs extending radially from the central body. The blocking cam is rotatable between a locked mode wherein one of the tabs obstructs removal of a bone anchor from a fixator port of the structural support device and an unlocked mode wherein the bone anchor is unobstructed from removal from a fixator port.

Abstract: An expandable interbody device for placement between adjacent vertebrae having an upper structure, a lower structure and a screw mechanism, wherein actuation of the screw mechanism moves the upper and lower structures between a collapsed configuration and an expanded configuration. A deployment tool couples to the expandable interbody device for positioning the device between adjacent vertebrae, actuating the screw mechanism and delivering a material to a chamber of the expandable interbody device.

Abstract: A method includes providing a ceramic matrix composite (CMC) seal arc segment that has radially inner and outer sides, attaching an abradable layer on the radially outer side of the CMC seal arc segment, providing a carrier to support the CMC seal arc segment, the carrier including a ridge, and sliding the CMC seal arc segment relative to the carrier such that during the sliding the ridge cuts a groove into the abradable layer, the ridge remaining disposed in the groove to thereby provide a labyrinth seal that partitions the cooling cavity between the carrier and the CMC seal arc segment into sub-cavities.

Abstract: A seal system for a gas turbine engine includes a ceramic matrix composite (CMC) seal arc segment and a carrier supporting the CMC seal arc segment. The CMC seal arc segment defines radially inner and outer sides and has an abradable layer disposed on the radially outer side. There is a cooling cavity radially between the carrier and the abradable layer. The carrier includes a ridge that projects into a groove in the abradable layer and provides a labyrinth seal that partitions the cooling cavity into sub-cavities.
