The methods and devices also prevent the medication applied to the SPG from flowing down a patient's throat during the procedure. ## Claims ### Claim 1 A device for delivering a medication to a patient, the device comprising: a handle comprising a proximal end and a distal end; an inflation device at least partially and integrally disposed within the handle; a flexible tubular member extending from the distal end of the handle, the flexible tubular member comprising a proximal end, a distal end, an inflation lumen coupled to the inflation device and extending from the proximal end of the flexible tubular member, and a second lumen extending from the proximal end of the flexible tubular member to a port; an expandable member attached to the flexible tubular member, the expandable member comprising a proximal end and as distal end, wherein the inflation lumen opens into the expandable member, wherein the port is disposed proximally of the proximal end of the expandable member; an illumination device disposed adjacent the distal end of the flexible tubular member and distally of the expandable member; a temporary power supply disposed within the handle; a switch having a closed position for activating the illumination device and open position for deactivating the illumination device; and a means for depleting the temporary power supply within a predetermined time regardless of whether the switch is the open position or closed position. ### Claim 2 (depends on 1) The device of claim 1, wherein temporary power supply comprises a battery. ### Claim 3 (depends on 1) The device of claim 1, wherein means for depleting the power supply in a predetermined time comprises a circuit having a second circuit path in parallel with a first circuit path for activating and deactivating the illumination device. ### Claim 4 (depends on 3) The device of claim 3 further comprising a pull tab for interrupting the second circuit. ### Claim 5 (depends on 1) The device of claim 1, wherein the illumination device is a light-emitting diode. ### Claim 6 (depends on 1) The device of claim 1, wherein the expandable member is an inflatable balloon. ### Claim 7 (depends on 1) The device of claim 1, wherein the inflation device comprises a plunger. ### Claim 8 (depends on 1) The device of claim 1, wherein the handle further comprising a pressure relief valve coupled to the plunger and the inflation lumen. ### Claim 9 (depends on 1) The device of claim 1, wherein the plunger comprises a housing, wherein the housing comprises a distal end and an opening disposed proximally of the housing's distal end. ### Claim 10 A device for delivering a medication to a patient, the device comprising: a handle comprising a proximal end and a distal end; an inflation device at least partially and integrally disposed within the handle, the inflation device comprising a plunger and a barrel, the barrel comprising a proximal end, a distal end, a wall between the proximal end of the barrel and the distal end of the barrel, and an opening through the wall, wherein the wall forms a chamber, the plunger comprising a seal and one or more locking arms having a length, whereupon the locking arms are capable of being disposed proximally and at least partially exterior of the barrel the seal is disposed within the chamber proximally of the opening; a flexible tubular member extending from the distal end of the handle, the flexible tubular member comprising a proximal end, a distal end, an inflation lumen coupled to the plunger and extending from the proximal end of the flexible tubular member, and a second lumen extending from the proximal end of the flexible tubular member to a port; an expandable member attached to the flexible tubular member, the expandable member comprising a proximal end and as distal end, wherein the inflation lumen opens into the expandable member, wherein the port is disposed proximally of the proximal end of the expandable member; and an illumination device disposed adjacent the distal end of the flexible tubular member and distally of the expandable member. ### Claim 11 (depends on 10) The device of claim 10, whereupon the locking arms are capable of being disposed in the chamber and adjacent a proximal orifice of the barrel such that the seal is disposed within the chamber adjacent or distal the opening. ### Claim 12 (depends on 10) The device of claim 10, whereupon the locking arms are capable of being disposed in the chamber and distal of a proximal orifice of the barrel such that the seal is disposed within the chamber distal the opening.
