Abstract: A surgical portal or portal system can include a portal assembly and a base plate assembly. The portal assembly can include a portal head and a portal stem disposed on a distal end of the portal head. The base plate assembly can include a depth stop disposed on a force dissipating plate. The depth of a working portal can be adjusted.

Abstract: Disclosed are instruments, implants and methods of accessing the spine from an Anterior to the Psoas (ATP) approach, performing a discectomy through an ATP approach and then placing an intervertebral implant via an ATP approach for spinal fusion.

Abstract: A surgical tube for spinal surgical procedures allows for lateral access to the L4/L5 disc space in the presence of a high iliac crest without going through the ilium. The tube has an angled jog that positions the distal portion of the tube on the cephalad side of the ilium. The angled tube can include fixation pin channels on the cephalad and caudal sides on the tube, going into the L4 and L5 vertebral bodies respectively. The L5 pin channel can have an angled inward portion corresponding to the jog of the tube, towards the center of L5. The L4 pin channel can be angled so that it starts at the caudal side of the tube at the proximal end of the tube and exits the tube on the cephalad side at the distal end of the tube.

Abstract: A floating clamp for surgical procedures includes a clamp body and a spring mechanism to allow in/out movement of a portal tube, while maintaining the tube's position in A/P and C/C. The clamp body includes a base portion and an arm pivotally coupled to the base portion such that a distal end of the arm pivots towards and away from a distal end of the base portion. The spring mechanism includes a coil spring and a piston disposed through the coil spring. The spring mechanism can be coupled to the clamp body adjacent to a proximal end thereof.

Abstract: A hybrid spinal implant for performing an intervertebral fusion procedure can include a pair of spacers separated by an expandable container that are formed of a porous titanium scaffold material. A connecting rod can span longitudinally between the pair of spacers. The spacers can be formed of titanium or PEEK, with endplates that are formed of the porous titanium scaffold material. The endplates can be bioactive. Exposed surfaces of the porous titanium scaffold material can be coated in a snag-preventing substance. The expandable container can be formed of a mesh material.

Abstract: A portal system for intervertebral surgical fusion procedures includes a longitudinally elongated hollow tubular body comprising a first wall, a second wall opposing the first and a third wall spanning from a first edge of the first wall to a first edge of the second wall. A channel is defined longitudinally through at least one of the first, second and third end walls. The fourth wall of the body is at least partially open or can be completely enclosed.

Abstract: A midline retractor provides access for the placement of PARS screws and other surgical sites. A lower profile allows for better visualization of the patients anatomy and provides better access for surgical instruments. The retractor may include integrated lighting, such as fiber optic lighting or other suitable lighting. The blades of the retractor may include a textured profile, such as diamond plating, grooves, etching or any other desired textured treatment on the blades. The texture on the blades may keep tissue from migrating down the blades and may prevent the blades from slipping up and out of the patient. The PARS retractor may include a blade rotation locking mechanism and/or a blade toe feature that allows for ease of use and an adjustable blade toe. The retractor may also include a rack release that provides for free movement of the rack.

Abstract: A bi-directional mechanically deployed rod mechanism utilizes non-parallel cam surfaces with a unique engagement, entrapment, and release methodology. The instrument utilizes a unique spring loading pivot point and lockout mechanisms to prevent early release of the pivot point and bi-directional cam surfaces.

Abstract: A tissue dissector can include a tool body having a proximal end and a distal end. The tool body can include a longitudinal path therein between the proximal end and the distal end. The path can include an arcuate portion disposed adjacent the distal end and a horizontal portion extending proximally from the arcuate portion. A cutting blade can be pivotably attached to the body with via a first pin. A central shaft can be coupled to the first pin. A handle assembly can be coupled to the central shaft. A second pin can be fixed to the cutting blade, engage the path of the tool body and be located offset from the first pin to pivot the blade about the first pin as the blade moves in a proximal direction from a farthest distal extent of the path in the tool body.

Abstract: An expanding dilator according to certain embodiments includes an expanding portion at its distal end. The expanding portion may expand once placed in the disc space thus seating the dilator in position. The expanding dilator may also include a stop feature to prevent the dilator from being placed too far. The expanding portion may expand by actuation of a knob or other actuator on the proximal end of the dilator. The expanding portion may expand incrementally.
