Cardiovascular Systems Acquires Gardia Medical’s WIRION™ Embolic Protection System

Cardiovascular Systems, Inc. has acquired the WIRION Embolic Protection System and related assets from Gardia Medical Ltd., a wholly owned Israeli subsidiary of Allium Medical Solutions Ltd. (TASE: ALMD).

The device, which received CE Mark in June 2015 and FDA clearance in March 2018, is a distal embolic protection filter used to capture debris that can be associated with all types of peripheral vascular intervention (PVI) procedures. Physicians typically use embolic protection devices in vessels located above the knee with long lesions, high plaque burden and poor run off.

Dr. Ehrin Armstrong, Professor of Medicine at the University of Colorado, said, “The use of an embolic protection device during peripheral interventions where the risk of embolization is higher provides assurance and protection from procedural complications.”

The WIRION System is easier to use and more versatile than other available embolic protection systems because it can be used with any .014” guidewire and for all types of peripheral interventions. In addition, the WIRION System is the only embolic protection device indicated for use with any atherectomy system. The WISE LE study also demonstrated a major adverse event (MAE) rate of 1.9%, which is lower than any other previously reported rates with other embolic filters. Importantly, no clinically significant distal embolization was observed when the WIRION System was used.

Asaf Alperovitz, Chief Executive Officer of Allium Medical Solutions, said, “Allium Medical’s mission is to develop innovative products to improve outcomes for patients around the world. We believe the WIRION System from Gardia Medical, one of our portfolio companies, will be highly synergistic with CSI’s growing portfolio of products. We will continue to partner with CSI to execute a timely manufacturing transfer and get the product in the hands of physicians.”

Scott Ward, CSI Chairman, President and Chief Executive Officer, said, “The acquisition of the WIRION System further supports our commitment and mission of building a comprehensive portfolio of differentiated products aimed at saving limbs and improving outcomes for patients undergoing complex peripheral interventions.”

CSI plans to commercialize the WIRION System in the United States following the transfer of manufacturing from Gardia Medical. CSI expects the manufacturing transfer to be completed after a 12- to 15-month transition period. Gardia will retain the rights to the WIRION System for angioplasty and stenting procedures in the carotid arteries.

About WISE LE

WISE LE (WIRION™ EPS in Lower Extremities Arteries) was a multicenter study, performed in the United States and Germany and included all commercially-available atherectomy systems. The primary endpoint was freedom from major adverse events (MAEs) occurring within 30 days post-procedure and was compared with an objective performance goal derived from historical atherectomy trials. MAE was defined as a serious adverse event that resulted in death, acute myocardial infarction, thrombosis, pseudoaneurysm, dissection (grade C or greater), or clinical perforation at the filter location, clinically relevant distal embolism, unplanned amputation, or clinically driven target vessel revascularization. The study also included a histopathological analysis of debris captured by the filter during the procedures.

About Cardiovascular Systems, Inc.

Cardiovascular Systems, Inc., based in St. Paul, Minn., is a medical device company focused on developing and commercializing innovative solutions for treating vascular and coronary disease. The company’s OAS treat calcified and fibrotic plaque in arterial vessels throughout the leg and heart in a few minutes of treatment time, and address many of the limitations associated with existing surgical, catheter and pharmacological treatment alternatives. The U.S. FDA granted 510(k) clearance for the use of the Diamondback Orbital Atherectomy System in peripheral arteries in August 2007. In October 2013, the company received FDA approval for the use of the Diamondback Orbital Atherectomy System in coronary arteries. The Stealth 360® Peripheral Orbital Atherectomy System (OAS) received CE Mark in October 2014. Over 450,000 of CSI’s devices have been sold to leading institutions worldwide.

WIRION™ Embolic Protection System

The WIRION™ is indicated for use as an embolic protection system to contain and remove embolic material (thrombus/debris) while performing angioplasty and stenting procedures in the carotid arteries and atherectomy in calcified lesions of the lower extremities. The diameter of the vessel at the site of the filter basket placement should be between 3.5mm to 6.0mm. WIRION™ may be used with commercially available 0.014” guidewires.
