Direct Flow Medical has announced that it has received the CE mark for a 23mm sized valve as part of its Direct Flow Medical transcatheter aortic valve system, expanding the patient population that can be treated with its technology. The company also announced receipt of the CE mark for implantation of all of 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 23mm, 25mm, 27mm and 29mm valves, which can treat patients with annulus sizes from 19mm to 28mm. 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 haemodynamic 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,” says Bernard Lyons, chief executive officer 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% of patients undergoing TAVI, increasing their risk of peri-procedural complications, prolonged hospitalisation and mortality.
“Use of contrast during angiographic procedures is a well-documented cause of acute kidney injury,” says Direct Flow Medical chief medical officer Charles Davidson. “By eliminating or reducing the quantity of contrast administered during TAVI, we will be able to better protect the kidneys and minimise peri-procedural complications.”
The Direct Flow Medical transcatheter aortic valve system is commercially available in Europe. In the USA, the company is progressing towards regulatory approval and is currently enrolling patients in its SALUS pivotal trial.
