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

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.

Devices and methods for providing surgical access

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.

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 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.

Various exemplary methods and devices are provided for the delivery of spinal screws to a spinal implant site. A variety of exemplary configurations and implementations are provided, but, in general, a handheld tool is provided having a guide member with a lumen formed therein that is configured to deliver a spinal screw to a cervical spine implant. The tool can include various features that facilitate the delivery of the spinal screw to the implant. The tool can include a storage component, such as a magazine, that is configured to hold a plurality of spinal screws for delivery of multiple spinal screws during a surgical procedure.

Spinal screw handling

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., from a proximal end of the access device or a location disposed outside of the patient. The blade can be manipulated in various ways, such as by rotating the blade relative to the outer tube, translating the blade longitudinally relative to the outer tube, sliding an expander along the blade, driving a wedge between the blade and the outer tube, actuating a cam mechanism of the access device, and/or pivoting the blade relative to the outer tube.
