Abstract

Methods and devices 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 integrated in the handle, wherein the inflation device comprises a plunger extending from the distal end of the handle;

a flexible tubular member extending from 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 a 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.

2. The device of claim 1, wherein the handle further comprises a switch for activating the illumination device.

3. The device of claim 2, wherein the handle further comprises a power supply for the illumination device.

4. The device of claim 3, wherein the flexible tubular member comprises conductors that couple the power supply to the illumination device.

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. The device of claim 1, wherein the handle is ergonomically shaped.

11. 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 integrated in the handle, wherein the inflation device comprises a plunger extending from the distal end of the handle;

a flexible tubular member extending from the handle, the flexible tubular member comprising a proximal end, a distal end, an inflation lumen extending from the proximal end, a second lumen extending from the proximal end to a port disposed proximally of the distal end of the flexible tubular member;

an expandable member attached to the flexible tubular member, wherein the inflation lumens opens into the expandable member, wherein the port is disposed proximally of the expandable member, and

a pressure relief valve disposed within the handle and coupled to the plunger and the inflation lumen.

12. The device of claim 11, wherein the plunger comprises a housing, wherein the housing comprises a distal end and an opening disposed proximally of the housing'"'"'s distal end.

13. The device of claim 11 further comprising an illumination device located at the distal end of the flexible tubular member.

14. The device of claim 13, wherein the handle further comprises a switch for activating the illumination device.

15. The device of claim 14, wherein the handle further comprises a power supply for the illumination device.

16. The device of claim 15, wherein the flexible tubular member comprises a conductor that couples the power supply to the illumination device.

17. The device of claim 11, wherein the inflation device comprises a plunger.

18. The device of claim 11, wherein the handle is ergonomically shaped.
