Abstract: An expandable interbody device used as a prosthesis during spinal surgery. The expandable interbody device is configured to be inserted into the space between spinal disks to provide stability. The expandable interbody device includes a drive block, a linkage block, a drive screw, a first endplate, a second endplate, and at least two linkages. Rotation of the drive screw causes movement of the linkage block relative to the drive block and/or movement of the first endplate relative to the second endplate.

Abstract: Disclosed herein is a surgical instrument configured for attachment to a surgical device. The surgical instrument includes a distal region having a curved internal surface configured to mate with a curved external surface of the surgical device, a rotational locking feature that limits rotational movement of the instrument with respect to the surgical device, and an axial locking feature that limits axial movement of the blade with respect to the surgical device. Methods of using the surgical instruments include sliding the axial locking feature past a corresponding axial locking feature on the surgical device, locking the axial locking feature to the corresponding axial locking feature on the surgical device (thereby limiting axial movement of the elongated blade with respect to the surgical device), adjusting the position of the surgical device using the surgical instrument, and disengaging the axial locking feature (for example, by using a disengagement instrument).

Abstract: A metal alloy and that includes an enhancement coating material. The metal alloy includes rhenium and one or more additives. The enhancement coating is at least partially applied to the metal alloy by a physical vapor deposition (PVD) process, a chemical vapor deposition (CVD) process, an atomic layer deposition (ALD) process, a plasma-enhanced chemical vapor deposition (PE-CVD) process, ion implantation, direct energy deposition (DED), and/or thermal spray techniques like plasma arc spraying, flame spraying, high velocity oxy fuel spraying (HVOF). The enhancement coating is formed of a) 35-95 wt. % zirconium and wherein said enhancement coating includes ZrN, ZrNC, ZrOC or a combination of ZrN and ZrO2, b) 20-85 wt. % titanium and one or more of carbon, nitrogen, oxygen, rhenium, and silicon, c) 40-85 wt. % chromium and one or more of carbon, nitrogen, oxygen, rhenium, and silicon, or d) at least 60 wt. % carbon.

Abstract: An expandable interbody device used as a prosthesis during spinal surgery. The expandable interbody device is configured to be inserted into the space between spinal discs to provide stability. The expandable interbody device includes a drive block, a top endplate, a bottom endplate, a first drive arrangement, and a second drive arrangement; the first drive arrangement includes a first drive screw, a first left side slide, a second left side slide, a first upper left side linkage, a second upper left side linkage, a first lower left side linkage age and a second lower left side linkage; and the second drive arrangement includes a second drive screw, a first right side slide, a second right side slide, a first upper right side linkage, a second upper right side linkage, a first lower right side linkage and a second lower right side linkage.

Abstract: A prosthetic heart valve that is at least partially coated with an enhancement layer, and a method for inserting the prosthetic heart valve in a patient. The prosthetic heart valve includes an expandable frame, a leaflet structure, and optionally an inner skirt and/or an outer skirt. One or more of the components of the prosthetic heart valve can be partially or fully coated with the enhancement layer. One type of enhancement layer that can be used includes titanium oxynitride or titanium nitride oxide (TiNOx) and/or zirconium oxynitride (ZrNxOy).

Abstract: An orthopedic fixation device and bone plating system for fracture fixation and methods for using the bone plating systems.

Abstract: Various implementations described herein include a screw locking receiver. The screw locking receiver includes a receiver frame which has a first surface, a second surface opposite and spaced apart from the first surface, and an inner surface which extends between the first surface and the second surface. The receiver frame defines a cylindrical inner channel having a central axis. The receiver includes a counterbore which extends along a first portion of the inner surface. The receiver includes a plurality of threads extending helically about a second portion of the inner surface. The counterbore has a diameter that is sufficient to accept a screw head having a non-parallel central axis with respect to a central axis of the inner channel when in a fastened position.

Abstract: Spinal cage devices, systems, and methods of assembly and implanting the devices and systems are disclosed. The cage system includes a cage and at least one locking screw assembly configured to couple to the cage. The spinal cage system includes a cage with a body portion, an external plate, and a rod. The body portion includes at least one opening positioned between the first and second ends, a center opening in the first end, and at least one hole adjacent the center opening. The external plate includes an opening and at least two holes on opposite sides of the opening. The rod extends through the center opening in the cage, the first end configured to couple to the external plate, and the second end positioned in the at least one opening. Methods for assembling a spinal cage system and for implanting a cage system are also disclosed.

Abstract: Systems and associated methods for ultrasonically-assisted placement of orthopedic implants are described herein. An example system includes an ultrasonic generator, a transducer, and a probe, surgical instrument, and/or an implant. Ultrasonic energy can be delivered to a region of a bone using the system to remove a portion of the bone.

Abstract: Various implementations include an implant. The implant includes a body defining a central opening. The body has a first surface and a second surface spaced apart and opposite from the first surface. The second surface at least partially defines the central opening. The first surface defines a plurality of openings including a first opening and a second opening. Each of the openings extends along an axis from the first surface to the second surface. The first opening and the second opening at least partially overlap at the first surface, and the axis of the first opening is transverse to the axis of the second opening.

Abstract: A prosthetic heart valve for the treatment of structural heart disease wherein the prosthetic heart valve includes an expandable frame that is formed of a rhenium containing metal alloy. The novel geometry of the expandable frame in combination with the frame being partially or fully formed of the rhenium containing alloy enables the formation of a frame that a) has an open cell geometry in the frame of the prosthetic heart valve that can be used to reduce delivery system size, b) has high radial strength, c) has improved restoration of the physiologic EOA, d) has lower recoil, e) has little or no longitudinal foreshortening, f) allows for proper placement of the bioprosthetic valve in relation to the native commissures of the valve, h) has symmetrical and cylindrical expansion of the prosthetic valve resulting in lower rates of leaflet thrombosis and structural valve deterioration, and i) prevents allergic response and restenosis associated with nickel content.

Abstract: Systems and methods for ultrasonically-assisted placement of orthopedic implants is described herein. An example method may comprise delivering ultrasonic energy to a surgical instrument such as a screw driver, Jamshidi needle, awl, probe, or tap that is in contact with the bone region targeted for removal and/or being prepared for implant placement. The method may further comprise delivering the ultrasonic energy via a probe passed through a cannulated surgical instrument and/or implant. An example system may comprise an ultrasonic generator coupled to a transducer, a probe or surgical instrument coupled to the transducer, a cannulated surgical instrument that allows passage of the probe, and a computing device configured to control the ultrasonic generator and take input from the user.
