Abstract

Methods and devices to quickly and accurately locate the sphenopalatine ganglion (SPG) while performing a sphenopalatine ganglion block procedure that introduces a medication to the SPG. The methods and devices also prevent the medication applied to the SPG from flowing down a patient'"'"'s throat during the procedure.

Claims

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.

2. The device of claim 1, wherein temporary power supply comprises a battery.

3. 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.

4. The device of claim 3 further comprising a pull tab for interrupting the second circuit.

5. The device of claim 1, wherein the illumination device is a light-emitting diode.

6. The device of claim 1, wherein the expandable member is an inflatable balloon.

7. The device of claim 1, wherein the inflation device comprises a plunger.

8. The device of claim 1, wherein the handle further comprising a pressure relief valve coupled to the plunger and the inflation lumen.

9. 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.

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.

11. 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.

12. 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.
