The dura and the MMA
The dura is the pain-sensitive lining around the brain. The middle meningeal artery (MMA) supplies it. Research shows this dura–MMA system is a central driver of migraine pain — and that many migraine medications act on this exact pathway.
TEMMA acts on the same pathway mechanically. By closing the MMA with a small coil, the abnormal pain signals to the dura are reduced at their source.
The procedure is performed by fellowship-trained neurointerventional specialists and typically takes 40 minutes, with patients returning home the same day.
