MediPro Pain & Performance is proud to be the preferred provider of SphenoCath for the Northwest.

Unique treatment with SPG/V2 block. SPG block stands for sphenopalatine ganglion block. V2 refers to the branch of the trigeminal nerve. The sphenopalatine ganglion itself is a collection of nerve cells located just under the tissue lining the back of the nose. By applying a local anesthetic to the area, nerve impulses can be temporarily blocked, providing relief from various types of pain, as well as dysautonomia and neurological symptoms.

Sensory, sympathetic, and parasympathetic fibers pass through or synapse in the SPG, making it a key structure in various types of cephalgia and neurological conditions. Temporarily blocking the function of the SPG can provide prompt and sometimes sustained relief of pain.

It is also theorized that an SPG block provides sustained relief by disrupting dysfunctional neuronal activity, allowing for the restoration of normal function.

The SPG/V2 is also part of a complex that connects the areas of the brain responsible for pain signaling as well as overlaps signaling from the stellate and vagal nerves making it appropriate to help with conditions such as PTSD, persistent sympathetic tone, visceral (organ) pain, and similar conditions. Not all indications are FDA-approved.

The most common medication used for an SPG block is a local anesthetic such as lidocaine. At Medipro, we can also employ a variety of unique and specialized medications specific to your condition. This could include regenerative tissue matrixes, peptides, or nutrients such as NAD or Rg3.

SphenoCath FAQ

What Can Be Treated With an SPG/V2 Block or Treatment?

A variety of conditions are appropriate for treatment. Migraine and chronic headaches are the most common indication but many other conditions can be effectively treated, including but not limited to nerve pain (trigeminal, supraorbital, occipital, etc.), central pain syndromes (Fibromyalgia, CRPS, neuropathies), autonomic dysfunction (POTS or visual-vestibular disorders), visceral pain (hypersensitivity due to gastrointestinal disorders and pelvic pain such as vulvodynia and interstitial cystitis), as well as persistent states resulting in increased sympathetic tone or vagal nerve dysregulation (seen in anxiety, PTSD, and many forms of depression). Targeting the SPG/V2 complex also allows for the delivery of specialized medication that addresses underlying root causes of the dysfunction and helps to induce repair from things like a traumatic brain injury.

How Is the Procedure Performed?

The procedure is done using the SphenoCath® device. SphenoCath® is a one-of-a-kind patented, soft, flexible, spaghetti-sized catheter that 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.

  1. Lay down with your chin tilted back.
    2. Your provider will gently place the SphenoCath® in your nose and direct it to the top of your nostril. Although most people report no pain at all during the procedure, you may feel a slight pinch the moment the tip of the device reaches the correct location.
    3. Once the SphenoCath® is properly inserted, your provider will deliver the medication to the target area to complete the procedure. They will then remove the SphenoCath® from your nostril.
    4. Lay flat for 10 minutes to ensure maximum benefit.

That’s it. No needles. No worries.


Will It Hurt?

Some patients experience minor discomfort when the small, soft SphenoCath® is inserted into the nose, but the procedure is not painful when performed correctly. We use a local anesthetic prior to insertion to reduce any potential discomfort. The patented SphenoCath® uses no needles and is designed to be comfortable and safe for patients.

How long will it How Long Will It Take?

SPG block using the SphenoCath® takes 2-3 minutes. Patients are encouraged to remain in a flat or reclined position for 10-15 minutes afterward to maximize the benefit of the procedure.

What Medications Are Used?

The medication choice is up to your healthcare provider. At Medipro, we will discuss and review the various options appropriate for your individual condition.

What Are the Side Effects or Risks Associated With SphenoCath®?

The risks of using SphenoCath® include irritation to the nasal cavity or mucosa, nose bleeding, and/or mild pain.

Why Haven’t I Heard of SPG Block Before?

The SPG block has been described in medical literature for over 100 years. It has been proven effective for many painful conditions but, until the invention of the patented SphenoCath®, the procedure has been difficult, uncomfortable, and offered only by a few practitioners. Medipro is one of a select few clinics to offer this procedure.

What About My Medications?

Do not change your medications unless instructed to do so by your provider.

What Are The Benefits?

Benefits of using the SphenoCath® device in an SPG/PPG block procedure:

  • 2 to 5-minute in-office procedure
  • The majority of patients experience immediate relief
  • Very low risk
  • Very high success rates
  • Safe for adults and children
  • Potential for reimbursement by most insurance companies and Medicare (Patient-submitted)

Photobiomodulation therapy is defined as the utilization of non-ionizing electromagnetic energy to trigger photochemical changes within cellular structures that are receptive to photons. Mitochondria is particularly receptive to this process. At the cellular level, visible red and near infrared light (NIR) energy are absorbed by mitochondria, which perform the function of producing cellular energy called “ATP”. The current and widely accepted proposal is that low level visible red to near infrared light (NIR) energy is absorbed by mitochondria and converted into ATP for cellular use. In addition, the process creates mild oxidants (ROS), which leads to gene transcription and then to cellular repair and healing. The process also unclogs the chain that has been clogged by nitric oxide (NO).[1] The nitric oxide is then released back into the system. Nitric oxide is a molecule that our body produces to help its 50 trillion cells communicate with each other. This communication happens by transmission of signals throughout the entire body. Additionally, nitric oxide helps to dilate the blood vessels and improve blood circulation thus reducing inflammation and pain.
