CENTER VALLEY, Pa. (December 15, 2021) — Olympus Corporation and Medivators announced today the termination of the pending patent infringement action brought by Olympus in March 2021 regarding the AmplifEYE™ products. The settlement resolves the pending action before the Texas court alleging Medivators’ infringement of two of Arc Medical’s patents. Medivators has announced it will cease the sale or distribution of AmplifEYE products after December 31, 2021. The specific terms of the agreement remain confidential.

About ENDOCUFF

The patented ENDOCUFF™ device, invented by Arc Medical, is an assistive technology for colonoscopy that has been shown to increase the rate of adenoma detection by as much as 11 percent compared to standard colonoscopy.i Research shows that, for every 1% increase in ADR, there is a 3% reduction in the risk of interval colorectal cancer and a 5% reduction in the risk of fatal colorectal cancer (CRC).ii Higher detection rates and more accurate diagnosis through screening can reduce the number of deaths from preventable digestive cancers, such as colorectal cancer, which is a leading cause of cancer death for both men and women worldwide.iii

Attaching to the distal end of a colonoscope, the flexible ENDOCUFF arms smooth the large folds of the mucosa lining the colon, allowing the physician to inspect more of the mucosal surface area for abnormalities. The action of the ENDOCUFF arms also anchor the scope tip during loop reduction and stabilize the scope tip during complex procedures, such as a polypectomy.

In addition, a recently published meta-analysis of randomized controlled trials concludes that consistent use of the ENDOCUFF VISION™ device was associated with a significant improvement in adenoma detection rate, adenomas per colonoscopy, and a reduction in the mean withdrawal time without any increase in adverse events compared to unassisted colonoscopy.iv
