The new device, which comes with two needle choices including a 3/8 circle needle and a 1/2 circle needle, is made of non-absorbable polytetrafluoroethylene (ePTFE) microstructure.

The porous microstructure has 50% air by volume to allow for tissue in-growth, claims the company.

On-X Life Technologies president Clyde Baker said, "The launch of this new product along with our submission to the FDA/CE authorities of an application to modify the Instructions for Use (IFU) for the On-X valve to lower anticoagulation levels than the previously recommended by profession society guidelines last October, gives us every indication that 2013 will be a remarkable year as we continue to develop products that make it easier for surgeons to repair and replace diseased valves and safer for patients."

The company said the product is being launched at the Society of Thoracic Surgeons (STS) 49th annual meeting held at Los Angeles, US.
