MINNEAPOLIS, April 28, 2026 (GLOBE NEWSWIRE) -- Nuwellis, Inc. (Nasdaq: NUWE), a medical technology company committed to delivering solutions for patients with cardiorenal conditions, announces that the U.S. Patent and Trademark Office (USPTO) has issued a Notice of Allowance for a new patent covering its novel dual lumen midline catheter technology designed for use in ultrafiltration therapies.
This next-generation catheter incorporates advanced design elements to optimize blood flow dynamics during therapy. The technology includes separate withdrawal and infusion lumens with pressure-balancing features that help maintain stable flow and reduce complications associated with fluid removal procedures.
The catheter design is further enhanced by a segmented reinforcement structure that allows clinicians to customize catheter length at the bedside while preserving kink resistance and consistent flow performance. This improves ease of use across a wide range of patient anatomies and may reduce interruptions during therapy.
“The allowed patent, ‘Dual Lumen Catheter,’ reflects Nuwellis’ continued investment in innovation to improve fluid management solutions and expand the clinical utility of our Aquadex SmartFlow® system,” said Nuwellis’ CTO David Lerner and the named inventor on the patent application. “Our team has focused on solving real-world clinical challenges in ultrafiltration therapy, and this technology reflects our commitment to improving both patient outcomes and clinician experience through thoughtful design and engineering.”
Once the patent issues, the patented catheter technology is expected to complement Nuwellis’ existing product portfolio and support the company’s strategy to expand access to ultrafiltration therapy in both hospital and outpatient settings.
