Abstract: Surgical access port stabilization systems and methods are described herein. Such systems and methods can be employed to provide ipsilateral stabilization of a surgical access port, e.g., during spinal surgeries. In one embodiment, a surgical system can include an access port configured for percutaneous insertion into a patient to define a channel to a surgical site and an anchor configured for insertion into the patient's bone. Further, the access port can be coupled to the anchor such that a longitudinal axis of the access port and a longitudinal axis of the anchor are non-coaxial. With such a system, a surgeon or other user can access a surgical site through the access port without the need for external or other stabilization of the access port, but can instead position the access port relative to an anchor already placed in the patient's body.

Abstract: Adjustable-length surgical access devices are disclosed herein, which can advantageously allow an overall length of the access device to be quickly and easily changed by the user. The access devices herein can reduce or eliminate the need to maintain an inventory of many different length access devices. In some embodiments, the length of the access device can be adjusted while the access device is inserted into the patient. This can reduce or eliminate the need to swap in and out several different access devices before arriving at an optimal length access device. This can also reduce or eliminate the need to change the access device that is inserted into a patient as the depth at which a surgical step is performed changes over the course of a procedure. Rather, the length of the access device can be adjusted in situ and on-the-fly as needed or desired to accommodate different surgical depths.

Abstract: An expandable intervertebral cage includes vertically opposed superior and inferior plates and longitudinally opposed distal and proximal wedges disposed between the plates. The wedges define ramps that engage complimentary ramps of the superior and inferior plates to increase a vertical distance between the plates. An actuator is located between the plates, defines a central, longitudinal axis, and is coupled to the wedges such that, as the actuator rotates about the axis, at least one of the wedges moves longitudinally relative to the other, thereby increasing the vertical separation distance. At least one locking component is insertable within a receptacle at least partially defined by the proximal wedge and is configured to transition from an unlocked configuration, where the actuator is rotatable relative to the proximal wedge, to a locked configuration, where the actuator is rotationally affixed relative to the proximal wedge.

Abstract: 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.

The system includes a carrier having a longitudinaly 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.

Abstract: Surface features for device retention are disclosed herein, e.g., for retaining an access port within a patient during a surgical procedure. The surface features can prevent ejection of the access port from a body of a patient. The surface features can be positioned along the access port and configured to glide along body tissues with minimal friction so as not to hinder travel of the access port in an insertion direction. After insertion of the access port, the surface features can engage with surrounding tissue to increase friction therebetween and to prevent ejection of the access port from the patient. Deployment of the surface features can occur due to friction with the surrounding tissue and/or via activation of the surface features to protrude from the access port. The surface features can include teeth, hooks, scales, fins, bristles, braids, and/or threads for engaging tissue.

Abstract: Devices and methods for surgical retraction are described herein, e.g., for retracting nerve tissue, blood vessels, or other obstacles to create an unobstructed, safe surgical area. In some embodiments, a surgical access device can include an outer tube that defines a working channel through which a surgical procedure can be performed. A shield, blade, arm, or other structure can be manipulated with respect to the outer tube to retract an obstacle. For example, an inner blade can protrude from a distal end of the outer tube to retract obstacles disposed distal to the outer tube. The inner blade can be movable between a radially-inward position and a radially-outward position. The radially-inward position can allow insertion of the blade to the depth of the obstacle to position the obstacle adjacent to and radially-outward from the blade. Subsequent movement of the blade to the radially-outward position can retract the obstacle in a radially-outward direction. The blade can be manipulated remotely, e.g.
