Abstract: An adjustable intervertebral implant for implantation into a patient's spine in-between first and second adjacent or neighboring vertebrae. The implant may include one or more of the following features: (i) inner and outer members coupled by a radiographically imagable expansion ring, (ii) detachable endplates coupled to the implant via a polygonal press-fit coupling interface that accommodate a range of lordotic endplates to be applied to the implant using any surgical approach, (iii) an interference pre-loaded set screw for selectively locking the height of the construct, (iv) a radiographically imagable marker for determining the expansion of the implant, and (v) an asymmetric thread coupling between the expansion ring and the inner member.

Abstract: The use of red or near infrared light upon neurons of the lumbar plexus that are in distress due to retraction-induced ischemia. The surgeon may protect nerves made ischemic in the surgery by: a) making an incision in a patient, b) inserting an access device into the patient through the incision to at least partially create a path to a spine of the patient, and c) irradiating nervous tissue adjacent the path with an amount of NIR or red light effective to provide neuroprotection.

Abstract: The disclosure extends to methods, systems, and computer program products for controlled illumination in a light deficient environment.

Abstract: The present invention is directed an anchor assembly for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The anchor assembly preferably includes a bone anchor, a body with a rod-receiving channel, an insert member (preferably a bushing), and a locking cap with a saddle. The anchor assembly preferably enables in-situ assembly where the bone anchor may be secured to the patient's vertebra prior to being received within the body of the bone anchor assembly. Accordingly, the anchor assembly enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body may be snapped onto the bone anchor and a spinal rod may be inserted into the rod-receiving channel.

Abstract: A separate nub component between the plate and an intervertebral fusion cage, wherein the nub is attached to the plate. The nub lessens the undesired pivotal movement of the plate. It is believed that when the nub fits snugly between the endplates of the adjacent vertebral bodies, it acts as a stop against the undesired pivotal movement of the plate.

Abstract: An intervertebral implant frame that is configured to engage a spacer can include a pair of arms that extend longitudinally from a support member such that the arms engage the spacer. The spacer can be made from bone graft, and include a first spacer body made of cortical bone, and a second spacer body made of cancellous bone.

Abstract: A disassembly tool for disassembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty. The tool includes a first member having a radial portion operably associated with the first component and adapted to exert a radial force on the first component. A second member operably associated with the second component is also included and the second member has a second member longitudinal axis. A drive mechanism is coupled to the second member, such that as the drive mechanism is activated, the second member exerts a force against the second component in the direction of the longitudinal axis. Such exertion of force against the second member further causes the second member to move relative to the first member along the second member longitudinal axis.

Abstract: The disclosure extends to methods, systems, and computer program products for producing an image in light deficient environments with luminance and chrominance emitted from a controlled light source.

Abstract: A bone fixation system has a bone implant with an implant body. The implant body defines an upper surface, a bone-facing surface spaced from the upper surface along a transverse direction, and at least one aperture defined by an inner wall. A bone fixation element is configured for insertion at least partially through the aperture. The bone fixation element defines a proximal end and a distal end spaced from the proximal end along a central axis. The bone fixation element has a head and a shaft that extends relative to the head toward the distal end. The head defines a first ridge, a second ridge spaced from the first ridge, and a groove disposed between the first and second ridges. The groove can receive at least a portion of the inner wall to couple the bone fixation element to the bone implant.

Abstract: A method of surgically implanting a glenoid component into the glenoid of a patient is disclosed. The method includes securing a rasp guide into the glenoid of the patient. The method also includes oscillating a surgical rasp over the rasp guide to form a cavity that is shaped to receive the glenoid component. The method also includes implanting the glenoid component in the cavity.

Abstract: A device for straightening and stabilizing the vertebral column, particularly for stabilizing broken vertebrae, includes a supporting implant which is plastically expandable by internal pressure. The supporting implant can be placed into the interior of a vertebral body which has been fractured under compression or between adjacent vertebral bodies. A pressure balloon to which pressure fluid can be admitted may be arranged in the interior of the supporting implant for producing the internal pressure.

Abstract: A force dissipating impactor device comprises a bar member including a hollow shaft, a first end, and a second end. The first end of the impactor device provides an impaction surface and the opposite second end of the impactor device provides an implant engagement surface. The implant engagement surface is contoured to mate with a surface of the implant member. The impaction surface is configured to be struck with a mallet or other tool. A plurality of holes are provided in the shaft and penetrate the surface of the bar member. The plurality of holes provided on the shaft surface of the bar member may be arranged such that a line passing axially along the shaft surface intersects at least one of the plurality of holes. Further, the plurality of holes may be arranged in a staggered matrix around the shaft surface.

Abstract: A growing rod for mounting between attachment mechanisms that are secured to anatomical structures of a patient having scoliosis. The growing rod includes an outer housing and an inner housing disposed within the outer housing. The inner housing includes a magnet assembly including a magnet having a first pole and a second pole and a gear reduction mechanism coupled to the magnet. A first rod is secured to the inner housing and a second rod is secured to the outer housing. The gear reduction mechanism reduces an output rotation of the magnet to rotate a driver that operates to move the inner housing along a longitudinal axis with respect to the outer housing.

Abstract: A setting adjustment tool for a magnetically adjustable device implanted in a patient includes a circumference. A plurality of magnetic coils can be circumferentially distributed on a circumference of the tool. One of the magnetic coils can be movable along the circumference between a plurality of predetermined positions associated with the selectable performance settings. The magnetic coils may also be capable of attracting or repulsing the at least one magnet of the rotor of the implanted device in a radial direction by at least a predetermined angle within a plane of rotation of an at least one magnet of the rotor thereby inducing a rotating moment into the rotor.

Abstract: A catheter device that includes a double-threaded guidance wire that allows multiple use of a compliant cavity creation device (i.e., treatment of more than one level). The double-threaded guidance wire may be connected with the luer part of the device and a distal part of the balloon using a threaded engagement to avoid lengthening of the inner tube, avoid lengthening of the balloon, and to limit the plastic deformation of the system in axial direction. In other implementations, the double-threaded guidance wire may be reconnected to the distal part of the balloon with a distal thread of the double-threaded guidance wire in order to restore the nominal length.
