Abstract: Enforcing shadow stack violations at module granularity, rather than at thread or process granularity. An exception is processed during execution of a thread based on code of an application binary, which is enabled for shadow stack enforcement, that calls an external module. The exception results from a mismatch between a return address popped from the thread's call stack and a return address popped from the thread's shadow stack. Processing the exception includes determining that the exception resulted from execution of an instruction in the external module, and determining whether or not the external module is enabled for shadow stack enforcement. Based at least on these determinations, execution of the thread is terminated when the external module is enabled for shadow stack enforcement, or the thread is permitted to continue executing when the external module is not enabled for shadow stack enforcement.

Abstract: A method of manufacturing an intervertebral implant comprising forming the implant with at least one dimension that is greater than a desired dimension, the implant comprising a superior bone facing surface, an inferior bone facing surface, a distal side, a proximal side, and lateral sides; coating at least the superior bone facing surface and the inferior bone facing surface with an osteophilic material; and machining one or more of the distal side, proximal side and lateral sides to the desired dimensions after coating; wherein edges of the coating on the superior bone facing surface and the inferior bone facing surface are machined to be flush with the distal side, proximal side and/or lateral sides.

Abstract: A flexible plunger rod, drug delivery mechanism, drug delivery device, and methods are described that utilize the flexible plunger rod perform drug delivery operations. In embodiments, the flexible plunger rod can be stored in a curved configuration to thereby reduce a footprint of the drug delivery mechanism and device.

Abstract: A program is executed using a call stack and shadow stack. The call stack includes frames having respective return addresses. The frames may also store variables and/or parameters. The shadow stack stores duplicates of the return addresses in the call stack. The call stack and the shadow stack are maintained by, (i) each time a function is called, adding a corresponding stack frame to the call stack and adding a corresponding return address to the shadow stack, and (ii) each time a function is exited, removing a corresponding frame from the call stack and removing a corresponding return address from the shadow stack. A backtrace of the program's current call chain is generated by accessing the return addresses in the shadow stack. The outputted backtrace includes the return addresses from the shadow stack and/or information about the traced functions that is derived from the shadow stack's return addresses.

Abstract: Devices for fixing interbody fusion devices to bone by helically or corkscrew-shaped elements are provided. Methods for surgically implanting an interbody fusion device using helically-shaped fixation wire are provided.

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: A walled work platform or man basket configured for positioning near a surface to be drilled, the platform comprising at least one drill assembly mounting point on a leading edge of the platform wall and a tension member connected to the platform wall adjacent the drill assembly mounting point and extending rearwardly for connection at a rear portion of the platform wall.

Abstract: Surgical tools having a tool portion, a handle and a light are disclosed. The tool portion has a first connector that couples to a second connector on the handle. The light can illuminate the working end of the surgical tool. The light can be energized when the tool portion and the handle are coupled. A plurality of different types of tool portions can be coupled to the handle. Methods of using surgical tools having a light are also disclosed.

Abstract: A dual wall storage container assembly is provided for storing liquids. The container includes a one-piece, molded inner tank which can be installed and removed from a molded outer tank. Notches are provided adjacent the bottom of the outer tank to align the inner tank within the outer tank. A horizontal shelf surrounds the mouth of the outer tank, with a horizontal shoulder on the top of the inner tank overlying the shelf. A seal is provided between the shelf and the shoulder to inhibit moisture migration. A drip edge is provided on the top outer perimeter of the inner tank to further inhibit moisture migration between the shelf and the shoulder. A tab on the shoulder is received in a notch in the shelf to preclude rotation between the nested tanks. Lifting flanges on the outer tank allow both tanks to be lifted simultaneously while nested together.
