Nobles Medical Technology II Receives FDA Approval to Resume NobleStitch™ Clinical Trial for PFO Closure

Nobles Medical Technology II's Journey Towards Innovative Cardiovascular Solutions

In a significant accomplishment for innovation in cardiovascular medicine, Nobles Medical Technology II has announced the U.S. Food and Drug Administration's (FDA) approval to resume its pivotal NobleStitch™ clinical trial. This marks a crucial step forward in the development of a pioneering suture-mediated system designed to close patent foramen ovale (PFO), thereby aiming to reduce the recurrence of cryptogenic stroke.

Understanding the NobleStitch™ System

The NobleStitch™ technology is a unique solution that provides a device-free means of closing PFOs. This innovative approach leverages a proprietary percutaneous suturing technique that eliminates the need for permanent implants, thus significantly reducing the potential complications associated with conventional closure methods, such as nickel hypersensitivity and long-term adverse events from implanted devices.

Originally designed to evaluate the efficacy and safety of the NobleStitch EL™ system, the clinical trial was proactively paused by Dr. Anthony Nobles, Chairman and CEO of Nobles Medical Technology II. This precautionary step was taken to enforce stringent safety protocols and ensure that the trial's design and execution met the highest scientific standards.

With the green light from the FDA, the company is now poised to reinstate patient enrollment and advance crucial data collection, which supports a broader FDA indication for its non-device closure platform. This approval couldn't have come at a better time, coinciding with the publication of a pivotal peer-reviewed study in the September 2025 edition of the Journal of the American College of Cardiology Advances. The findings from this study bolster the clinical rationale for suture-based closure and illustrate the transformative potential of the NobleStitch™ technology, promoting it as a standard of care in PFO management.

Commitment to Safety and Innovation

Dr. Anthony Nobles expressed his enthusiasm for the restarted clinical trial, emphasizing the FDA's approval as a validation of the advanced technology and trial design. He stated, "This decision reflects confidence in our technology, our trial design, and our commitment to advancing safer, more effective solutions for patients suffering from cryptogenic stroke and other PFO-related conditions."

He also highlighted that the pause in the trial allowed for the strengthening of the protocol and data collection methods. This meticulous approach illustrates the company's commitment to gathering robust data that will substantiate the safety and efficacy of the NobleStitch™ system. The anticipated completion of the trial will culminate in a Pre-Market Approval (PMA) application submission, further underscoring Nobles Medical Technology II's role in shaping the future landscape of cardiology.

To further enhance its clinical trials, Nobles Medical Technology II has partnered with Rush University Medical Center, showcasing Dr. Josh Murphy as a leading expert in PFO closure, who will provide additional insights and support throughout the trial process.

Looking Forward to the Future

The company expects to resume patient enrollment in the fourth quarter of 2025. The forthcoming data from the trial and potential PMA submission could set a new paradigm for patients with PFO, emphasizing a future where device-free solutions dominate PFO closure strategies.

Nobles Medical Technology II is dedicated to completing the clinical trial with an emphasis on meticulous data collection, aiming for widespread adoption of this innovative solution within the medical field. By harnessing its patented NobleStitch™ technology, the company is reshaping the way healthcare professionals approach cardiovascular defects, delivering safer alternatives that prioritize patient care.
