The submission includes Implantica's responses to FDA's remaining questions and requests, including the completion of additional testing requested by the Agency following the previously announced 100-Day Meeting, review of all three PMA modules, and multiple pre-approval inspections conducted by FDA. The six preapproval inspections, including manufactoring sites, Quality System, and BIMO (clinical trial inspections), were all successfully concluded as reported in the closing meetings.

Dr. Peter Forsell, founder, CEO, and inventor of RefluxStop®, says, "The submission of our final response to FDA marks a major milestone for Implantica and reflects many years of extensive clinical, scientific, regulatory, and operational work. We are grateful for FDA's thorough and constructive review throughout this process."

Dr. Forsell continues, "RefluxStop® has all the attributes to transform the surgical treatment of GERD in the United States. The strong and growing interest we continue to see from leading surgeons and gastroenterologists, together with the excellent long-term clinical outcomes demonstrated across multiple studies and real-world patient populations, further strengthens our confidence in the future potential of RefluxStop®. We now look forward to the completion of the PMA review process and bringing RefluxStop® to patients in the U.S., pending FDA approval."

RefluxStop® is a unique surgical treatment for gastroesophageal reflux disease (GERD) designed to restore the natural anatomy of the body without compressing the food passageway. The PMA application is supported by extensive long-term clinical data, including the company's pivotal clinical study with the 5-year follow-up requested by FDA, the results of which have been published in two peer-reviewed scientific papers demonstrating excellent long-term safety and efficacy outcomes for RefluxStop®.

About RefluxStop®
RefluxStop® is a treatment for GERD designed to address the root cause of acid reflux without compressing the food passageway.

Unlike conventional anti-reflux surgical procedures, which typically rely on encircling the esophagus and are often associated with side effects such as swallowing difficulties, inability to belch or vomit, and gas bloating, RefluxStop® restores and maintains the lower esophageal sphincter in its natural anatomical position.

The unique mechanism of action of RefluxStop® is designed to reconstruct the body's natural anti-reflux barrier while preserving normal physiological function, offering the potential for effective reflux control with reduced side effects compared to traditional surgical approaches.
