A flexible surgical access port is provided that includes a flexible body. The flexible body is configured to elastically expand in response to passage of a surgical equipment therethrough, and thus retracts as the surgical equipment moves past. Thus, the flexible body can provide a surgical access path through Kambin's Triangle, and large surgical equipment passed through the flexible body does not compress the exiting nerve or the traversing nerve root for a prolonged period of time.

Flexible surgical access port

An expandable trial can include an inferior portion, a superior portion, and a middle expanding portion as well as load cells for monitoring the load on the trial. The trial may also include recesses on its lateral sides to provide spacing to accommodate a disc removal tool so tissue can be cleared monitoring load. In addition, neural foramen spacing can be monitoring to provide information about how much neural release has been achieved as the disc is cleaned and the spine is positioned and repositioned.

Methods and devices for spinal correction

A system for delivering flowable biomaterial to an intervertebral disc space between adjacent vertebral bodies includes a delivery body defining a proximal end, a distal end spaced from the proximal end along a longitudinal direction, a cannulation extending from the proximal end to an opening adjacent the distal end, and a distal region including a tip that extends to the distal end. The distal region defines a maximum height at a location proximal of the distal end and measured along a second direction perpendicular to the longitudinal direction. The distal region is for indicating a distance between the adjacent vertebral bodies. The system includes a carrier having a longitudinally elongate channel for carrying biomaterial and being insertable within the cannulation, as well as an advancement member configured for insertion within the cannulation to forcibly advance the biomaterial from the cannulation, through the opening, and into the disc space.

Biomaterial delivery device, and related systems and methods

Devices and methods for minimally invasive disc space distraction and implantation are provided. For example, in intervertebral operative spinal procedures, separate or pre-attached spreader blocks can be used to control the directional growth of a distracting balloon. The spreader blocks can provide an initial distraction of the disc space while the distracting balloon provides further distraction of the disc space. When distraction is achieved, an intervertebral implant may be inserted into the distracted disc space. After the implant is firmly implanted, the balloon and spreader block may be removed.

Balloon with shape control for spinal procedures

Various methods and devices are provided for tensioning a tether. In one embodiment, a tether tensioning device is provided and includes an elongate shaft adapted to be positioned adjacent to a bone anchor implanted in bone, and a tensioning mechanism pivotally associated with the elongate shaft and adapted to couple to a tether seated across the bone anchor and to pivot relative to the elongate shaft to apply a tensioning force to the tether.

Instruments and methods for tensioning a spinal tether

An intervertebral fusion device comprising inferior and superior fusion cage devices that provide an ability to correct spondylolisthesis via in-situ adjustment.

Lateral spondylolisthesis reduction cage

Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member. The distal portion of the wing can define a bone anchor opening through which one or more auxiliary bone anchors can be disposed to augment the fixation of the assembly's primary bone anchor. A distal surface of the distal portion of the wing can be obliquely angled relative to a proximal-distal axis of the spanning portion to face one of a caudal direction or a cephalad direction. A distal surface of the distal portion of the wing can be obliquely angled relative to the proximal-distal axis of the spanning portion to face one of a medial direction or a lateral direction. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Multipoint fixation implants and related methods

The present disclosure relates to methods and devices for surgically manipulating tissue. In general, the methods and devices can include an elongate retractor shaft having a distal retractor tip that is configured to manipulate tissue, for example the tip can be configured to separate muscle and nerve fibers surrounding a vertebra. The elongate retractor shaft can include an illumination source such that at least a portion of the surgical field is illuminated by the device when the device is used in the body. A sensor can also or alternatively be included on the elongate retractor shaft, for example on the blunt retraction tip, such that the sensor can monitor physiological parameters of the tissue in or adjacent to the surgical field.

Surgical retractors

An interbody fusion cage having upper and lower canals for receiving the heads of bone screws that have been pre-installed in opposing vertebral body endplates. The proximal wall of the cage preferably has a vertical slot that communicates with each canal and is adapted to allow access by a screwdriver and tightening of the screws.

Zero profile spinal fusion cage

A novel posterolateral inter-muscular approach has been developed to access the cervical. spine. The approach includes elevating the splenius capitis and trapezios muscles dorsally to create a window for deep spine access, wherein the window comprises: Preferably, a device such as an implant or an instrument is then passed through the window to manipulate the spine.

Method and devices for a sub-splenius/supra-levator scapulae surgical access technique

A novel posterolateral inter-muscular approach has been developed to access the cervical spine. The approach includes elevating the splenius capitis and trapezius muscles dorsally to create a window for deep spine access, wherein the window comprises: Preferably, a device such as an implant or an instrument is then passed through the window to manipulate the spine.

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.

Nubbed plate

Devices and methods for enhancing the effectiveness of spinal stabilization, and particularly that of cervical spinal stabilization, are provided herein. More specifically, methods and systems are disclosed for effectively positioning occipital plates and spinal fixation assemblies within target vertebrae, while also reducing any associated patient trauma (e.g., muscle stripping, tissue damage, etc.). The systems and methods can utilize trans-lamina delivery of the spinal fixation assemblies to allow for the positioning of the fixation elements along the midline of the patient's spine.
