Pulsante Procedure

About the Pulsante Procedure

A Simple Procedure

The Pulsante® SPG Microstimulator is inserted through a minimally invasive procedure that leaves no visible scars.

Typically performed in an operating room, your surgeon will make a small incision (approximately 2cm) in your upper gum above the molars on the side where you suffer cluster headaches.1 A natural pathway along the bone above your molars called the pterygopalatine fossa allows the Microstimulator to reach the SPG nerve bundle.


The procedure is comparable to oral cavity interventions, such as a wisdom tooth removal.1 The body of the inserted Microstimulator is about the size of an almond and cannot be seen. Most patients find it to be comfortable and cannot even feel it.

Once your surgeon is satisfied with the position of the Microstimulator, they will secure it to your upper jaw with tiny surgical screws and fully test it to ensure everything is in working order.

What are the risks of the procedure?

Please discuss the risks and benefits with your doctor to determine if Pulsante® Therapy procedure is right for you. Risks of neurostimulation therapy can include surgical risks, possible side effects, or device complications. Your doctor can provide more information about these and other potential risks. Please follow your doctor’s instructions after surgery to minimize surgical risk.

Most common side effects from the procedure occur within 30 days and are mild and temporary.The side effects are similar to those reported in other oral procedures which include post-operative pain, swelling and sensory disturbances (such as numbness).1 In a majority of patients, the side effects resolved within three months.2,3

It is important to follow your doctor’s instructions for taking any medication, including antibiotics and to report any side effects from the procedure to your doctor.
