Meet Stephen Nardi

Inventor and Founder of The SURV™ Catheter Slide Valve Device

“As the inventor, my goal in creating SURV was to provide catheter users with greater dignity, mobility, and confidence in their daily lives. I believe this simple and affordable solution has the potential to make a meaningful difference for both patients and healthcare providers.” — Stephen Nardi

Tagline: Designed to SURV the catheter-wearing community.

In the highly specialized world of medical devices, incremental improvements can have outsized consequences. For Stephen Nardi, an inventor based in Cleveland, Ohio, that principle guided the development of his Catheter Slide Valve Device. SURV™ is the brand name for the innovative catheter slide valve device designed to improve dignity, mobility, and quality of life for catheter users.

Catheter systems are widely used across healthcare settings, from hospitals to outpatient care facilities, yet their reliability and ease of use remain critical concerns. Even small inefficiencies in valve control can introduce risk, complicate procedures, or reduce clinician confidence. Nardi identified an opportunity to refine how catheter valves function, focusing on improving control, usability, and consistency in real-world clinical environments.

That effort culminated in the issuance of U.S. Patent No. 12,485,266, titled “Catheter Slide Valve Device.” The patented design reflects a thoughtful approach to mechanical precision, featuring a sliding valve mechanism intended to provide smoother operation and more dependable fluid regulation. While the concept may appear straightforward on the surface, its implications are significant: greater control can help improve procedural outcomes and reduce complications in situations where precision is essential.

What distinguishes Nardi’s invention is its grounding in practical application. Rather than pursuing complexity for its own sake, the device addresses a tangible challenge faced by healthcare professionals and catheter users every day. Innovations like SURV™ may not attract widespread public attention, but they play an essential role in modern healthcare by quietly improving patient safety, workflow efficiency, independence, and quality of life.

Securing patent protection marks a significant milestone in the innovation journey. Within the medical device industry, intellectual property often serves as the bridge between concept and commercialization. It provides the legal foundation necessary to pursue strategic partnerships, manufacturing opportunities, investment, or licensing discussions. Obtaining patent protection not only recognizes the novelty of an invention but also strengthens its position within a competitive and highly regulated marketplace.

Like many inventors working in technical fields, Nardi’s path underscores the importance of persistence. Medical device innovation requires navigating multiple layers of product development, engineering refinement, regulatory awareness, and intellectual property strategy. Progress is rarely linear. Each stage, from identifying the initial problem to refining the final design, demands technical expertise, careful planning, and long-term commitment.

The patent was secured with the guidance of Binita Singh, Patent Attorney at Bold Patents, whose legal strategy helped successfully guide the invention through the U.S. patent process. In an industry where precision extends beyond engineering, experienced patent counsel plays a vital role in ensuring that valuable innovations receive strong, enforceable intellectual property protection.

As the medical device industry continues to evolve, innovations like the SURV™ Catheter Slide Valve Device demonstrate how focused engineering can drive meaningful improvements in patient care. Whether through future licensing opportunities, manufacturing partnerships, or widespread clinical adoption, Nardi’s work reflects a practical philosophy: solve an important problem well, and meaningful impact can follow.

Looking ahead, the foundation established by U.S. Patent No. 12,485,266 provides this Ohio inventor with a strong platform for the next phase of commercialization. As the invention moves from protected intellectual property toward real-world implementation, it has the potential to make a measurable difference where it matters most, in the hands of healthcare professionals and the individuals who rely on catheter care every day.
