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.
Claims12
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.

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.
