S&P 500 slips, but losses kept in check as Nvidia climbs ahead of results
MINNEAPOLIS - Nuwellis, Inc. (NASDAQ:NUWE), a medical technology company with annual revenue of $8.79 million and a robust gross margin of 64.89%, announced Tuesday it has been granted U.S. Patent No. 12,357,734 for its "Extracorporeal Blood Filtering Machine and Methods" by the United States Patent and Trademark Office. According to InvestingPro analysis, the company currently appears undervalued based on its Fair Value assessment.
The newly issued patent covers methods for improving accuracy in fluid balance calculations during continuous renal replacement therapy (CRRT) by accounting for varying densities of replacement fluids and effluent. According to the press release, most current systems assume a standard fluid density of 1 g/mL, which can lead to clinically relevant errors in fluid balance measurements.
The patented approach enables CRRT systems to incorporate actual fluid density through user input, machine measurement, or derived data, potentially resulting in more precise volumetric flow tracking.
"Expanding our intellectual property portfolio is a key part of our strategy," said John Erb, Chief Executive Officer of Nuwellis, in the company statement. "Each new patent reinforces our commitment to building long-term value through innovation that supports patients, clinicians, and our future growth." The company maintains a strong balance sheet, with InvestingPro data showing more cash than debt and a healthy current ratio of 2.23.
Nuwellis, which focuses on fluid management solutions, markets the Aquadex SmartFlow system for ultrafiltration therapy. The system is indicated for temporary or extended use in adult and pediatric patients weighing 20 kg or more whose fluid overload is unresponsive to medical management, including diuretics.
The company stated this patent joins its growing portfolio of pending U.S. patents related to its proprietary systems and methods. The medical technology company is headquartered in Minneapolis with a wholly owned subsidiary in Ireland.
