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: providing an injection catheter formed of an elongated body, the injection catheter including an internal lumen and a directional injector at least partially positioned inside the lumen; inserting the injection catheter into a body vessel near a region surrounding a sinus nerve; exiting a portion of the directional injector from the injection catheter via an exit port of the injection catheter such that the directional injector of the injection catheter can apply anesthetic selectively to the region surrounding a sinus nerve; anchoring the injection catheter by deploying a stiff member to which the injection catheter couples; extending the directional injector to deliver anesthetic to the region surrounding a sinus nerve; and applying anesthetic from the injection catheter to the region surrounding a sinus nerve.
