ENDOLUMINAL DELIVERY OF ANESTHESIA
First Claim
1. A method of applying anesthetic to a target structure from within a body vessel without substantially applying anesthetic to non-target structures, the method comprising:
- inserting an injection catheter into a body vessel, wherein the injection catheter comprises a directional injector configured to apply anesthetic selectively to the target structure;
positioning the injection catheter within the body vessel near the target structure;
anchoring the injection catheter;
extending the directional injector to deliver anesthetic to the target structure; and
applying anesthetic from the injection catheter to the target structure.

Abstract
Described herein are methods and devices for selectively applying fluids (particularly anesthetics) to a target tissue from within a blood vessel while minimizing the amount of fluid applied to non-target tissue. The injection catheters described herein may include an elongate body, a directional injector, and one or more holdfasts for securing the catheter before extending the injector. The methods of selectively applying anesthetic to a target structure generally include the steps of inserting an injection catheter into a body vessel, positioning the injection catheter within the body vessel near the target structure, anchoring the injection catheter before extending a directional injector from the injection catheter, and applying anesthetic from the injection catheter to the target structure.

11. A method of applying anesthetic to a subject'"'"'s sinus nerve from within the carotid artery, the method comprising:
-
inserting an injection catheter into the carotid artery, wherein the injection catheter comprises a directional injector configured to apply anesthetic selectively to the sinus nerve; positioning the injection catheter within the carotid artery near the sinus nerve; anchoring the injection catheter; extending the directional injector to selectively deliver anesthetic to the sinus nerve; and applying anesthetic from the injection catheter to the sinus nerve.

12. A method of applying anesthetic to a target tissue from within a blood vessel while minimizing the amount of anesthetic applied to non-target tissue, the method comprising:
-
inserting an injection catheter into a blood vessel, wherein the injection catheter has a directional injector configured to controllably release anesthetic and a holdfast configured to anchor the injection catheter within the blood vessel; positioning the injection catheter within the blood vessel adjacent to the target tissue by visualizing the directional injector and the target tissue; and applying anesthetic from the injection catheter to the target structure.
