Surgical device for performing a sphenopalatine ganglion block procedure
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.
1. A device for delivering a medication to a patient, the device comprising:
an ergonomically shaped handle comprising a proximal end and a distal end;
a syringe integrated in the ergonomically shaped handle, wherein the syringe comprises a barrel and a plunger, wherein a portion of the barrel is disposed within the ergonomically shaped handle, and the plunger is disposed within the portion of the barrel while the plunger extends from the proximal end of the ergonomically shaped handle;
a flexible tubular member extending from the ergonomically shaped 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 distally of the expandable member.
2. The device of claim 1 , wherein the ergonomically shaped handle further comprises a switch for activating the illumination device.
3. The device of claim 2 , wherein the ergonomically shaped 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 disposed adjacent the distal end of the flexible tubular member.
6. The device of claim 5 , wherein the illumination device is a light-emitting diode.
7. The device of claim 1 , wherein the expandable member is an inflatable balloon.
8. The device of claim 1 further comprising a pressure relief valve disposed within the ergonomically shaped handle.
9. The device of claim 8 , wherein the pressure relief valve is coupled to the plunger.
10. The device of claim 8 , wherein the pressure relief valve is coupled to the plunger and the inflation lumen.
11. 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.
12. A device for delivering a medication to a patient, the device comprising:
a handle comprising a proximal portion and a distal portion, wherein the proximal portion has a longitudinal axis;
a syringe integrated in the proximal portion of the handle, wherein the syringe comprises a barrel and a plunger, wherein a portion of the barrel is disposed within 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 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, wherein the inflation lumen opens into the expandable member, wherein the port is disposed proximally of the proximal end of the expandable member, whereupon inflation of the expandable member, the plunger is disposed within the portion of the barrel disposed within the handle; and
an illumination device disposed distally of the expandable member.
13. The device of claim 12 , wherein the distal portion of the handle has a second longitudinal axis.
14. The device of claim 13 , wherein the longitudinal axis of the proximal portion of the handle and the second longitudinal axis of the distal portion of the handle are offset.
15. The device of claim 14 , wherein the longitudinal axis of the proximal portion of the handle and the second longitudinal axis of the distal portion of the handle intersect and form curved profile for the handle.
16. The device of claim 15 , wherein the longitudinal axis of the proximal portion of the handle and the second longitudinal axis of the distal portion of the handle are offset at an angle between about 5 degrees about 60 degrees.
17. The device of claim 16 , wherein the longitudinal axis of the proximal portion of the handle and the second longitudinal axis of the distal portion of the handle are offset at an angle between about 10 degrees about 45 degrees.
18. The device of claim 17 , wherein the longitudinal axis of the proximal portion of the handle and the second longitudinal axis of the distal portion of the handle are offset at an angle between about 20 degrees about 30 degrees.
19. The device of claim 12 , wherein the expandable member comprises a proximal end and a distal end, and wherein the illumination device is disposed distally of the distal end of the expandable member and adjacent the distal end of the flexible tubular member.
