Stratus® Medical announces issuance of third United States patent for the Nimbus® RF Multitined Expandable Electrode used in the treatment of pain

MAGNOLIA, Texas, Feb. 23, 2021 /PRNewswire/ — Stratus® Medical, a company focused on advancing radiofrequency ablation (RFA) treatment for chronic pain, announced today that the United States Patent and Trademark Office has granted a third U.S. patent related to its Nimbus® RF Multitined Expandable Electrode. U.S. Patent No. 10,925,664, titled METHODS FOR RADIO FREQUENCY NEUROTOMY, issued on February 23, 2021.

Stratus Medical’s newest U.S. patent contains 29 method claims, including claims directed to nerve ablation for pain relief. These claims provide broad protection for Stratus Medical’s Nimbus technology. Stratus Medical now holds three U.S. patents and 18 patents outside the U.S. on this technology, with several additional patent applications pending.

Bret Boudousquie, Stratus Medical CEO, shared: “Nimbus radiofrequency ablation (RFA) is an important and rapidly growing treatment option for millions of patients suffering with chronic pain. We are delighted with the expansion of both our U.S. and international patent portfolios to protect our technology in the marketplace. Nimbus is rapidly building market share due to its numerous clinical advantages over other large volume lesion RFA options, including faster procedure times, ease of use and lower procedure cost. We expect to see continued growth as Interventional Pain Medicine Physicians increase their utilization of RFA with new procedure applications such as the knee, where coverage and payment was established in 2020 and improved significantly in 2021. Until recently, less than 1% of the of the millions of newly diagnosed knee arthritis patients have been treated with RFA. This presents opportunity to help many chronic pain patients with the Nimbus technology.”

The Nimbus® RF Multitined Expandable Electrode addresses the unmet need for an easy-to-use and cost-effective RFA device which provides a large volume lesion for sustained pain relief.

Background:

Radiofrequency neurotomy (RFN) can be an effective treatment for patients with chronic neck pain and cervicogenic headaches resistant to conservative care. However, the degree and duration of pain relief after RFN is dependent upon the thoroughness of target nerve coagulation.

Case Report:

This is a case of a 37-year-old patient with debilitating neck pain and headaches following a motor vehicle accident. Successful local anesthetic block of the third occipital nerve (TON) confirmed pain of C2-C3 facet joint origin. An initial RFN treatment of the TON, using standard 18G electrodes in bipolar mode, resulted in complete symptom amelioration for 8 months. Repeat RFN, using the same electrode configuration, was unsuccessful in alleviating the severe neck pain and headaches, and produced no demonstrable sensory loss in the distribution of the TON. RFN was then performed using the NIMBUS® electrosurgical RF multitined expandable electrode, which provides a larger zone of coagulation in volume than standard RFN electrodes even when used in bipolar configuration.

Conclusion:

The NIMBUS procedure resulted in successful coagulation of the TON with sensory loss in the TON distribution and reinstatement of palliative relief.
