Stratus Medical announced today that it received three new patents for its radiofrequency (RF) ablation treatment for chronic pain.

Magnolia, Texas-based Stratus said in a news release that the patents, which issued in the U.S., Brazil and India, highlight the growth of its intellectual property portfolio for its highly differentiated ablation technology.

The patents include the fourth issued in the U.S., the second in India and the first in Brazil for protecting Stratus’ Nimbus RF multitined expandable electrode device. Stratus now has 24 issued patents and 13 pending patent applications for its technology.

Stratus designed the Nimbus RF miltitined expandable electrode to address the unmet need for an easy-to-use and cost-effective RF ablation device that provides a large volume lesion for sustained pain relief.

“It is very important we continue to invest in protecting our highly differentiated and patented Nimbus technology, as we make rapid commercial progress,” Stratus Medical CEO Bret Boudousquie said in the release. “The Stratus Medical team is focused on making Nimbus the preferred large volume lesion nerve ablation technology to treat pain. We are proud to work with exceptional interventional pain medicine physicians around the world, who are utilizing Nimbus to improve the quality of life for their patients.”
