CHF Solutions Expands Intellectual Property Portfolio with Two New Patent Filings for Innovations to Aquadex FlexFlow® System

January 16, 2019

EDEN PRAIRIE, Minn., Jan. 16, 2019 (GLOBE NEWSWIRE) -- CHF Solutions (Nasdaq: CHFS) today announced the filing of two new patent applications with the United States Patent and Trademark Office (USPTO) designed to deepen the company’s intellectual property protection for its Aquadex FlexFlow system.

“CHF Solutions has long remained dedicated to innovation of its technology and optimizing the application of our Aquadex FlexFlow system for the treatment of fluid overload in a variety of settings,” said John Erb, chairman and CEO of CHF Solutions. “The new innovative features contained in these pending patent applications reflect that dedication.”

One of the two applications is based on the company’s design for a wearable device designed to assist in maintaining peripheral venous blood flow access in the arm during aquapheresis treatment with the Aquadex FlexFlow system. The second application includes multiple potential new features and improvements to the diagnostic capabilities of the Aquadex FlexFlow system, which, if incorporated into the product, would be designed to help ensure optimal patient fluid balance and to dramatically improve usability for healthcare providers.
