On-X Life Technologies(Austin, Texas) has announced the launch of its On-X Aortic Prosthetic Valve with Anatomic Sewing Ring and the Chord-X ePTFE Suture for mtiral valve chordae tendineae repair.
The prosthetic valve is made of On-X Pyrolytic Carbon, a proprietary pure form of isotropic pyrolytic carbon that is strong and the surface of which resists clot formation. The valve features a unique “Anatomic Sewing Ring” that adapts to the anatomy of the aortic annulus rather than the reverse, hopefully leading to better overall outcome for the patient. The company also touts the low blood turbulence levels of the valve, which should reduce the chances of thrombosis and keep more cells from being mechanically damaged.
The On-X valve is the result of a breakthrough in medical grade carbon technology—On-X® pure pyrolytic carbon. In addition to providing a more thromboresistant surface, the comparatively high strength of pure On-X Carbon® enabled On-X LTI to make significant valve design changes that resulted in a prosthesis that acts more like a natural valve in its treatment of blood. It is well documented that the On-X valve does not produce the turbulence and blood damage commonly produced by other mechanical heart valve prostheses and, therefore, significantly reduces the potential for life-threatening blood clots.
