August 29, 2014 — Direct Flow Medical announced it received CE mark for a 23 mm valve as part of its Direct Flow Medical transcatheter aortic valve system, expanding the patient population that can be treated with this technology. The company also announced receipt of the CE mark for implantation of all its valves without the use of contrast media, protecting patients from kidney injury during transcatheter aortic valve implantation (TAVI).
The company now has a valve portfolio that includes 23 mm, 25 mm, 27 mm and 29 mm valves, which can treat patients with annulus sizes from 19 mm to 28 mm. All Direct Flow Medical valves feature a unique, double-ring design that conforms to the anatomy and creates a tight and durable seal around the annulus. The valves allow for complete assessment of hemodynamic performance and unlimited repositioning until optimal results are obtained. All valves can be delivered through the same, low profile and flexible delivery system.
“These approvals are a testament to our continuous focus on innovation and patient outcomes. Physicians will not only be able to treat a broader patient population, but will also be able to implant this technology with no contrast and no compromises,” said Bernard Lyons, CEO of Direct Flow Medical. “Our pipeline of structural heart technologies is strong, and we continue to invest in new products and new indications for our unique therapeutic platform.”
The Direct Flow Medical valve is designed to improve TAVI outcomes by virtually eliminating aortic regurgitation, offering unlimited repositionability during the procedure and reducing overall complications. Acute kidney injury occurs in about 22 percent of patients undergoing TAVI, increasing their risk of peri-procedural complications, prolonged hospitalization and mortality.
“Use of contrast during angiographic procedures is a well-documented cause of acute kidney injury,” said Charles Davidson, M.D., chief medical officer of Direct Flow Medical. “By eliminating or reducing the quantity of contrast administered during TAVI, we will be able to better protect the kidneys and minimize peri-procedural complications.”
The Direct Flow Medical transcatheter aortic valve system is commercially available in Europe. In the United States, the company is progressing towards regulatory approval and is currently enrolling patients in its SALUS pivotal trial.
