Abstract
Various devices and methods for accessing and preparing treatment sites within the intervertebral disc space for subsequent negligible-incision surgical (NIS) or percutaneous procedures to treat disc degeneration and disc related back pain are disclosed. Also disclosed is a method for performing a percutaneous spine procedure including preparing a treatment site within the intervertebral disc space for subsequent delivery of a biomaterial to treat disc degeneration and disc related back pain.
Claims34
A tool for causing blood flow into a disc space, the disc space being defined in part by at least one vertebral endplate, the tool comprising:
- a first cutting element, the first cutting element being selectively disposable in a delivery configuration and in a deployed configuration, the first cutting element including a free end and being configured to engage the at least one vertebral endplate;
- a second cutting element, the second cutting element being selectively disposable in a delivery configuration and in a deployed configuration, the second cutting element including a free end and being configured to engage the at least one vertebral endplate;
- and
- a deflecting element, the deflecting element including a body portion having a deflecting surface, the deflecting surface being configured to direct the first cutting element and the second cutting element outwardly as each of the first cutting element and the second cutting element engages the deflecting surface.
A system for inducing blood flow into a disc space, the disc space being defined in part by a vertebral endplate, the system comprising:
- a cutting mechanism, the cutting mechanism being configured to engage the vertebral endplate, the cutting mechanism being selectively disposable in a delivery configuration in which the cutting mechanism has a first profile and in a deployed configuration in which the cutting mechanism has a second profile, the second profile being larger than the first profile, the cutting mechanism including at least one free end;
- an expander mechanism, the expander mechanism being configured to engage the at least one free end of the cutting mechanism to move the cutting mechanism from its delivery configuration to its deployed configuration;
- and
- a control mechanism, the control mechanism being coupled to the cutting mechanism, the control mechanism being configured to be used to impart motion to the cutting mechanism in its deployed configuration in which the at least one free end engages the vertebral endplate.
A site preparation device for inducing blood flow into a disc space, the disc space being defined in part by at least one vertebral endplate, the site preparation device comprising:
- a delivery device, the delivery device including an elongate body having a proximal end, a distal end, and a channel extending from the proximal end to the distal end, the body including a longitudinal axis;
- and
- a tool, the tool being configured to be inserted through the channel of the body, the tool including:
- a cutting element, the cutting element including a proximal end and a distal end, the distal end being a free end, the cutting element being selectively disposable in a delivery position substantially aligned with the longitudinal axis of the shaft and in a deployed position extending away from the longitudinal axis of the shaft, the cutting element being configured to engage the at least one vertebral endplate and cause blood to flow into the disc space;
- and
- an actuating element, the actuating element being movable to engage the cutting element to move the cutting element from its delivery position to its deployed position.
A method of performing a percutaneous spine procedure on a patient, the method comprising:
- inserting a delivery device into a spinal column of a patient;
- establishing a percutaneous pathway using the delivery device leading from a skin exit location to a disc space defined by at least one vertebral endplate;
- introducing a preparation device through the delivery device to the disc space, the preparation device including a support portion and a cutting portion, the cutting portion of the preparation device being selectively disposable in a delivery configuration and in a deployed configuration relative to the support portion;
- preparing the disc space by engaging the cutting portion of the preparation device with at least one vertebral endplate;
- and
- delivering a biomaterial through the delivery device to the prepared disc space to facilitate forming at least a partial arthrodesis between two adjacent endplates.
