Abstract: An orthopedic fixation system includes an orthopedic implant and a compression insert transitionable between a natural shape and an insertion shape. The orthopedic implant includes first and second plates with insert slots configured to receive therein a portion of the compression insert. The first and second plates secure with a bone in an opposed relationship while being separated by an expansion whereby the insert slots of the first and second plates align across the expansion. The compression insert, in the insertion shape, inserts into the insert slots of the first and second plates such that the compression insert spans the expansion. The compression insert, due to an attempted transition thereof from the insertion shape to the natural shape, delivers energy stored therein to the first plate and the second plate whereby the orthopedic implant affixes the bone.

Abstract: An implant can be implanted in an aneurysm to cause thrombogenesis within the aneurysm's sac. The implant can include a braid that can extend across the aneurysm neck and anchor to aneurysm's walls at least in the proximal portion of the aneurysm sac. The implant can further include a dome feature configured to press into aneurysm walls near the aneurysm's dome and facilitate securement of the braid across the aneurysm's neck. The braid at the aneurysm's neck and the dome feature can be joined or constricted at a junction, for instance with a radiopaque band. The dome feature can include a braid, embolic coil, and/or wire frame. The braid can be inverted based on a heat-set predetermined shape, where several predetermined shapes are suitable.

Abstract: An adjustable bone fixation device for moving a bone includes at least two strut units, at least one meter and a system controller. Each strut unit includes a motor to move a strut. The meter measures a signal generated by the motor during the movement of its strut. The signal is useful in determining a torque or a current of the motor. The system controller activates at least two of the motors and uses the determined torque or the determined current to identify if there is a clinical situation of the bone or a system issue and provides an alert accordingly.

Abstract: A motor-driven orthopedic impacting tool is provided for orthopedic impacting in the hips, knees, shoulders and the like. The tool is capable of holding a broach, chisel, or other end effector, which when gently tapped in a cavity with controlled percussive impacts, can expand the size or volume of an opening of the cavity or facilitate removal of the broach, implant, or other surgical implement from the opening. A stored-energy drive mechanism stores potential energy and then releases it to launch a launched mass or striker to communicate a striking force to an adapter in either a forward or reverse direction. The tool may further include a combination anvil and adapter and an energy adjustment mechanism to adjust the striking force the launched mass delivers to the adapter in accordance with a patient profile.

Abstract: Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided intervertebral implants. The arcuate fixation members may be of different lengths, cross sectional geometries, and/or cross sectional areas. Applications of intervertebral implants utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

Abstract: Systems, methods of manufacture, and packaging configurations are provided for an antimicrobial orthopedic implant having an antimicrobial coating on the outer surface of the implant including a vaporizable antimicrobial agent in a surface area concentration on the outer surface sufficient to prevent bacterial growth on the orthopedic implant, and can additionally provide a clinically effective zone of inhibition around the orthopedic implant. In certain embodiments, a container, a reservoir of the vaporizable antimicrobial agent, and the orthopedic implant are configured to remain thermally stable in a temperature range up to 200 C.

Abstract: An apparatus for controlling movement of a wire configured to deploy an implant is presented herein. The apparatus can include a wire including a bump and a valve including a friction element configured to apply a friction force to the wire. The friction force can vary based on one or more of: a speed at which the wire is pulled through the friction element, a direction in which the wire is pulled through the friction element, and a contact between the bump and the friction element. The wire can be configured to deploy an implant upon a proximal retraction of the wire.

Abstract: Systems, methods, and devices are disclosed for robotic surgical systems including a robotic arm, the systems comprising an end effector attached to the robotic arm and retaining an access guide, and an initial access tool detachably connected to the access guide, wherein the initial access tool comprises a housing, a shaft extending from the housing coaxially through the access guide, and a distal tip attached to the shaft and protruding from a portion of the access guide distal to the end effector, wherein the housing is adapted to prevent rotation with respect to the access guide. In some embodiments, the access guide is adapted to retain an initial access tool and one or more of a burring tool, a drilling tool, or a tapping tool.

Abstract: A bone plate has an outer surface, a bone-facing surface opposite the outer surface, and an interior surface that defines a hole extending from the outer surface to the bone-facing surface along a central hole axis. The interior surface further defines a ramp that extends from the outer surface toward the bone-facing surface and plate threads that extend from the ramp toward the bone-facing surface and are configured for optional locking engagement with external threads on a first head of a locking bone fixation member. The interior surface further defines a contact profile in a reference plane that extends along the central hole axis. The contact profile is defined at least by the ramp and is spaced from the central hole axis in an offset direction perpendicular to the central hole axis.

Abstract: Various exemplary surgical impacting tool interfaces and methods of using surgical impacting tool interfaces are provided. In general, a surgical impacting tool includes a locking assembly configured to releasably attach to an adapter. In response to engagement with the adapter, the locking assembly is configured to move from an unlocked configuration, in which the adapter is not releasably attached to the surgical impacting tool (nor is any other adapter releasably attached to the surgical impacting tool via the locking assembly), to a locked configuration, in which the adapter is releasably attached to the surgical impacting tool via the locking assembly. The locking assembly is configured to receive the adapter in a longitudinal direction along a longitudinal axis defined by the locking assembly and to automatically lock the adapter to the surgical impacting tool.

The device can be advanced over a guidewire inserted into a joint to a first position and the guidewire can be reversibly locked to the handle. The handle can be associated with an actuator configured to be actuated to cause the dilator shaft and/or sheath to advance distally toward a second position within the joint while simultaneously retracting the guidewire coupled to the handle.

Abstract: A torque wrench includes an elongated body, a head, and a cantilever beam. The body extends longitudinally from a proximal end to a distal end and includes a channel extending therethrough. The distal end includes an opening extending laterally therethrough along a central axis. The head is rotatably received within the opening at the distal end so that the head is rotatable about the axis. The head includes a gear cam defining teeth about a periphery thereof and an engaging portion sized, shaped, and configured to engage a corresponding engaging feature of a fixation device. The beam is housed within the channel such that a distal tip is received in a space between adjacent teeth. The beam bends when a torsional force applied to the head exceeds a predetermined limit so that the cam rotates about the axis and the distal tip slips from the space between the teeth into an adjacent space.
