Note 1 – Business Organization and Nature of Operations

The Company

enVVeno Medical Corporation (the “Company”) is a late-stage medical device company focused on the advancement of innovative bioprosthetic (tissue-based) solutions to improve the standard of care for the treatment of venous disease. The Company is developing a replacement venous valve for patients suffering from severe Chronic Venous Insufficiency (“CVI”) of the deep venous system of the leg.

The Company is focused on its next-generation, non-surgical replacement venous valve, called the enVVe® System. The enVVe System consists of the enVVe Valve, enVVe Delivery System, enVVe Nose Cone, the enVVe Delivery System Accessories, and the enVVe Crimping System. The enVVe Valve is a first-in-class transcatheter based replacement venous valve being developed for the treatment of severe, deep venous CVI. The enVVe Valve is designed to act as a one-way valve, to help assist in propelling blood up the veins of the leg, and back to the heart and lungs.

In April 2026, the U.S. Food and Drug Administration (“FDA”) awarded the Company an Investigational Device Exemption (“IDE”) approval to proceed with a U.S. pivotal study of the enVVe System. The Transcatheter Venous Valve Endoprosthesis (“TAVVE”) pivotal study will evaluate the Company’s minimally invasive enVVe System for patients with severe CVI.

The IDE approval positions the Company to advance what could become the first effective treatment option for the approximately 3 million U.S. patients who suffer from the debilitating impact of severe CVI due to malfunctioning valves in the deep veins of the leg.

The first stage of the TAVVE® study, which is expected to commence in the second half of 2026, will consist of 10 patients, whose 30-day safety results will be submitted to the FDA for review. This group of 10 patients will continue to be followed as a separate cohort throughout the study, and their safety and efficacy data will be reported publicly from time to time. The second stage of the study, which will begin immediately after the 30-day safety results for the first group are reported to the FDA, will enroll 220 patients, with 165 patients receiving the enVVe valve, and 55 patients randomized into a control arm who will receive standard of care treatment. The results from the patients who receive the enVVe valve will be compared to the results from the patients in the control arm of the study. The TAVVE study will enroll patients at up to 40 U.S. clinical sites and will include vascular surgeons, interventional radiologists and interventional cardiologists. One year after the 220th patient is enrolled in the second stage of the study, the Company would be eligible to file for FDA post-marketing approval.
