Surgical device for performing a sphenopalatine ganglion block procedure
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.
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.
