[ What is claimed is:] [1.] A method of applying a therapeutic agent to treat the canker sores of a patient, the method comprising:(a) inserting a device into the mouth of a patient, wherein the device has a distal section, a distal end, a proximal end, openings at both ends, and at least one lumen

[ What is claimed is:] [1.] A method of applying a therapeutic agent to treat the canker sores of a patient, the method comprising:(a) inserting a device into the mouth of a patient, wherein the device has a distal section, a distal end, a proximal end, openings at both ends, and at least one lumen extending therebetween, wherein rim electrode means is disposed at said distal end, and wherein said device is leak-proof except for the openings at the distal end and the proximal end;(b) contacting the device against the canker sores of a patient, wherein a distal surface plate of said rim electrode means covers the canker sore, and wherein said surface plate is permeable to medicament;(c) supplying a therapeutic agent to the canker sores, wherein a positive pressure is applied to said therapeutic agent from the proximal end of said device by fluid infusion means for pressurizing the therapeutic agent against the canker sores;(d) applying energy to the rim electrode means of the device, wherein the energy is selected from the group consisting of radiofrequency energy, microwave energy, ultrasonic energy, alternating current energy, and laser energy; and(e) maintaining contact of the therapeutic agent against the canker sores for a predetermined time.
