An expandable implant. The expandable implant includes a base member having a top surface and a bottom surface opposite the top surface, and an adjustable member adjustably coupled to the base member and movable between a first, collapsed position, and a second, expanded position. The adjustable member has a top surface and a bottom surface opposite the top surface. The top surface of the adjustable member and the bottom surface of the base member form a first angle while the adjustable member is in the first, collapsed position, and the top surface of the adjustable member and the bottom surface of the base member form a second angle while the adjustable member is in the second, expanded position. The first angle is different from the second angle.

An installation tool comprising a tool body, a control shaft disposed at least partially within the tool body, a tool interface coupled to the tool body, and a control plate housed within the tool interface. The tool comprising a body member coupled with the tool interface, the body member including a channel to receive a barb, a retention member to engage the barb to position the barb within the channel, and an interface to engage a surface of an implant to align the implant relative to the body member. The tool comprising a first arm and a second arm that are movable between a first configuration and a second configuration, where in the first configuration the first and second arms extend laterally away from the tool interface, and in the second configuration the first and second arms engage the tool interface and are configured to secure the implant.

A method for decorticating a vertebral endplate material from spinal vertebrae using a decorticating tool having height adjustable blades at a distal end of a shaft assembly, translates axial movement of a control rod of a shaft assembly of the vertebral endplate preparation tool with height adjustable blades into radial blade height change (extension and retraction) through a controller of a handle assembly. The blades may also be configured for collecting and removing shaven vertebral endplate material. The blades controllably move outward radially from the distal end of the shaft assembly and controllably move inward radially into the distal end of the shaft assembly upon manipulation of the controller. Radial blade extension and retraction from the distal end is accomplished via mutual angled dovetail features of the blades and the distal end, or via pins of the distal end of the shaft assembly situated in angled slots of the blades.

An implant includes an interbody device having a front, a rear, a first lateral side, a second lateral side, a central cavity, and a plurality of bores extending into the rear of the interbody device, each arced bore being configured to receive an arced anchoring member.

A method for installing an expandable interbody (intervertebral) spine implant with a two-piece medical instrument via an endoscope, the two-piece medical instrument having a handle assembly and a shaft assembly configured for extension through the endoscope, the shaft assembly holding an expandable interbody spine implant when the shaft assembly is fully received by a head of the handle assembly, and releasing the spine implant upon retraction of the shaft assembly from the head of the handle assembly. The shaft assembly has a rod with a longitudinal bore and a sleeve situated on the rod that axially moves relative to the rod in response to the reception into and retraction from the handle assembly head, with the sleeve controlling capture and release of the implant by the rod. The distal end of the rod has a clamp formed by jaws that flex to capture and release the implant.

A pituitary rongeur medical instrument has jaws that can controllably articulate radially along a 90° arc in a single radial direction from a longitudinal axis of a shaft assembly of the pituitary rongeur and beyond a perimeter of a cannula during use. The pituitary rongeur has a handle, a shaft assembly defining a proximal end extending from the handle, and a distal end, with the jaws pivotally connected to the distal end for limited articulating radial movement of the jaws relative to the longitudinal axis of the shaft assembly, a jaw controller associated with the shaft assembly and configured to controllably close and open the jaws, and an articulation controller associated with the shaft assembly and configured to controllably articulate the jaws. The handle has a handgrip portion configured to receive a palm of a user and a lever portion with a finger loop for receiving fingers of the user.

An expandable implant comprising a first support comprising a control aperture defined by and extending through the first support, a second support movably coupled to the first support, and a control assembly. The control assembly comprising a control shaft, a base member received on the control shaft, the base member configured to translate along the control shaft, and a pivot member pivotally coupled to the base member and movably coupled with the control aperture, where translation of the base member along the control shaft causes the pivot member to pivot relative to the base member, and the first support to move relative to the second support to change an angle between the first support and the second support.

An expandable implant includes a lower support; an upper support pivotally coupled to the lower support and including a control channel; and a control assembly. The control assembly includes a control shaft coupled to the lower support and a control member coupled to the control shaft and configured to move along the control shaft. The control member includes a base member and a pivot member pivotally coupled to the base member, the pivot member configured to move within the control channel. Movement of the control member along the control shaft causes the pivot member to pivot relative to the base member, and the upper support to pivot relative to the lower support.

A steerable implant comprising a first support member and a second support member coupled to the first support member, where at least one of the first support member and the second support member are movable between a collapsed position and an expanded position. The implant further comprises a first end member and a second end member movably coupled with the first support member and the second support member. The implant further comprises a first control member coupled with the second end member, where movement of the first control member at a first axis causes movement of a second control member at a second axis, and where the movement of the second control member causes movement of the first end member to move the at least one of the first support member and the second support member between the collapsed position and the expanded position.

An implant includes a first support, a second support rotatably coupled to the first support along a distal end of the implant, and a control assembly configured to move the implant between at least a first, collapsed orientation and a second, expanded orientation, the control assembly includes a control driver coupled to the first support and comprising a head and a shaft, the control driver configured to control relative movement between the first support and the second support, a control member configured to move along the shaft of the control driver, and a first linkage hingedly coupled to the control member and the second support, wherein movement of the control member causes the first support to move relative to the second support.
