Nuwellis receives notice of allowance for U.S. patent on Vivian system

Nuwellis (NUWE) announced that the United States Patent and Trademark Office has issued Nuwellis a notice of allowance for a new patent covering advanced safety mechanisms for blood return line clamps used in extracorporeal blood filtration systems, including the company’s Vivian Pediatric Continuous Renal Replacement Therapy System currently in development. Many extracorporeal blood filtration systems rely on automated clamps as part of their safety design to prevent air embolism or pressure imbalances. The newly patented technology enhances this core function by dynamically adjusting clamping force based on environmental factors, automatically reconditioning the tubing under defined thermal conditions, and adding thermal insulation for improved material stability. Together, these innovations strengthen one of the most critical safety components in pediatric extracorporeal therapy-ensuring consistent, reliable protection for the smallest patients.
