DEVICES AND METHODS FOR TREATING TISSUE
First Claim
1. A method for treating target tissue in a patient'"'"'s spine, the method comprising:
- advancing a wire into the patient from a first location, through a neural foramen, and out of the patient from a second location;
connecting a tissue modification device to the wire;
positioning the tissue modification device through the neural foramen using the wire;
modifying target tissue in the spine by moving the tissue modification device against the target tissue; and
delivering an agent to modified target tissue, wherein the agent is configured to inhibit blood flow from the modified target tissue.

Abstract
Described herein are devices, systems and methods for treating target tissue in a patient'"'"'s spine. In general, the methods include the steps of advancing a wire into the patient from a first location, through a neural foramen, and out of the patient from a second location; connecting a tissue modification device to the wire; positioning the tissue modification device through the neural foramen using the wire; modifying target tissue in the spine by moving the tissue modification device against the target tissue; and delivering an agent to modified target tissue, wherein the agent is configured to inhibit blood flow from the modified target tissue. In some embodiments, the step of modifying target tissue comprises removing target tissue located ventral to the superior articular process while avoiding non-target tissue located lateral to the superior articular process.

13. A method for treating target tissue in a patient'"'"'s spine, the method comprising:
-
advancing a wire into the patient from a first location, through a neural foramen adjacent to a facet joint having a superior articular process, and out of the patient from a second location; connecting a tissue modification device to the wire; positioning the tissue modification device through the neural foramen using the wire; and modifying target tissue in the spine by moving the tissue modification device against the target tissue to remove target tissue located ventral to the superior articular process while avoiding non-target tissue located lateral to the superior articular process. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A device for delivering an agent to tissue in a patient'"'"'s spine, the device comprising:
-
a elongate flexible catheter having a proximal end and a distal end, wherein the distal end of the elongate catheter is configured to be advanced into the patient from a first location and toward a neural foramen; a connector coupled to the proximal end of the catheter that remains outside of the patient and is configured to receive a syringe containing an agent; and an aperture at the distal end portion of the catheter configured to deliver the agent to the tissue.
