This is the original and only catheter developed by physicians for physicians to establish an SPG block. And it’s never been easier.

SPG blocks have time-tested efficacy when it comes to serious chronic and episodic migrainous pain as well as Trigeminal Neuralgia, other TAC and atypical facial pain syndromes.

With a quick and comfortable block of the SPG using our patented method and device, you’ll be able to bring immediate relief to the majority of patients. There are no needles, cotton swabs or systemic narcotics. View our short video below to learn more, then click below to request training and other peer-to-peer support.

Frequently Asked Questions

About the device:
The SphenoCath® device is a one-of-a-kind patented, soft, flexible, spaghetti-sized catheter which employs a flexible outer sheath with soft edges for comfort and an inner angled flexible catheter to deliver medication without the use of a needle inside the nasal passageway with maximum patient comfort. The device has a directional arrow for proper orientation within the nostril and can, optionally, include a tungsten tip and barium impregnated sheath for high visibility under fluoroscopic imaging, if needed. Depth markings on the external sheath are also available as an option.
Why is the SphenoCath® important?
The SPG block has been described in the medical literature for over 100 years. It has been proven effective for many painful conditions. The main limitation to the procedure has been that it is the discomfort and risks for patients and the inconsistency of medicine placement impacting results of the procedure. The SphenoCath® addresses all of those issues, making the procedure quick, easy and consistent.
What is SPG block and why should I consider it for my patient?
The sphenopalatine ganglion (SPG) is located just deep to the nasal mucosa posterior to the middle nasal turbinate. The SPG can be blocked by diffusion of local anesthetic through the overlying mucosa. Sensory, sympathetic and parasympathetic fibers pass through or synapse in the SPG, making it a key structure in various types of cephalgia. Temporarily blocking function of the SPG can provide prompt, and sometimes sustained, relief of pain. It is theorized that an SPG block provides sustained relief by disrupting dysfunctional neuronal activity, allowing restoration of normal function.
How can I learn to do this procedure?
The procedure is simple and can be performed successfully simply by following the instructions for use included with the device and available for review from our site soon. For further information, please contact us at or call (801) 386-9400.
What are the risks of an SPG block?
The risks for using the SphenoCath® include irritation to nasal cavity or mucosa, nose bleeding; and/or mild pain.
