Catheter Precision Files a Method-of-Use U.S. Patent Application for its VIVO™ Technology

Catheter Precision, Inc. (“Catheter Precision”), a medical device company focused on cardiac electrophysiology, announces the filing of a new U.S. patent application for its VIVO^™ (View Into Ventricular Onset) technology, as it continues its focus on patent protection for VIVO. On September 12, 2022 privately held Catheter Precision announced a definitive merger agreement with Ra Medical Systems (NYSE American: RMED), which, if completed, will result in a combined publicly traded company focusing on the cardiac electrophysiology market.

The VIVO technology currently has significant intellectual property protection, with both issued patents and pending patent applications. Catheter Precision has 35 issued patents and patent applications covering the VIVO technology, the Amigo® robotic system and its new closure device, which is anticipated to be commercialized in the first half of 2023.

David Jenkins, Catheter Precision CEO, commented, “A strong intellectual property portfolio is key to building and protecting value within any medical device company. As such, we have kept a keen eye on our engineering advancements and our vision of the future, with an awareness of our inventive activities. We are proud that we continue to identify new and promising opportunities with our VIVO technology upon which to file and expand our IP estate.”

VIVO, Catheter Precision’s lead product, is a non-invasive 3D imaging system that enables physicians to identify the origin of arrhythmias pre-procedure, thereby streamlining workflow and reducing procedure time. VIVO has received marketing clearance from the U.S. FDA and has been awarded the CE mark. Catheter Precision recently announced that the VIVO technology was featured in multiple presentations at the Society of Cardiac Robotic Navigation Annual Meeting in Budapest, Hungary.

Under the terms of the definitive merger agreement with Ra Medical Systems, Catheter Precision will become a wholly owned subsidiary of Ra Medical Systems in a stock-for-stock reverse merger transaction. The merger is expected to close before the end of 2022, subject to satisfying certain closing conditions, including the receipt of shareholder approval by both companies.

Proposed Merger Agreement

On September 12, 2022, Ra Medical (“Ra Medical” or the “Company” announced entering into an Agreement and Plan of Merger (the “Merger Agreement”) with privately held Catheter Precision, Inc., a medical device and technology company focused in the field of cardiac electrophysiology. Under the terms of the Merger Agreement, Catheter Precision will become a wholly owned subsidiary of Ra Medical in a stock-for-stock reverse merger transaction (the “Merger”). If completed, the Merger will result in a combined publicly traded company that will focus on the cardiac electrophysiology market, one of the most robust and growing areas of medical devices.

Catheter Precision has three product areas that it intends to pursue. Its lead product, named VIVO^™ (an acronym for View Into Ventricular Onset) is an FDA-cleared and CE mark product that utilizes non-invasive inputs to locate the origin of ventricular arrhythmias, and, through its use, the physician can identify patients for invasive catheter ablation, and with those patients, reduce the amount of time in the invasive procedure. Ventricular arrhythmias include ventricular tachyarrhythmias and premature ventricular arrhythmias, diseases that affect millions of patients who are not well treated today. While much past growth in the electrophysiology market has been for atrial fibrillation, Catheter Precision believes that ventricular arrhythmias represent a large growth area moving forward. It also intends to pursue a second generation of Amigo^®, a robotic arm previously cleared by the FDA and awarded the CE mark, which serves as a catheter control device that can be remotely controlled outside of the procedure room. Catheter Precision has demonstrated that patient outcomes could potentially be enhanced by utilization of this device. Catheter Precision is working toward a third product release in the first half of 2023, which is a vessel closure device that would assist in the closure of the insertion site of the percutaneous catheter or other device used within the body. It is estimated that the worldwide market for this closure assist device is over one million procedures per year.

The Merger is expected to close before the end of 2022, subject to satisfying certain closing conditions, including the receipt of shareholder approval by both companies.
