The On-X LTI story is unique among medical device companies because On-X LTI’s management and production teams have been at the forefront of the tandem technologies of carbon biomaterials and prosthetic heart valve design since the 1960’s. Our state-of-the-art On-X pure carbon bileaflet valve is attracting worldwide attention for its outstanding clinical performance.

The exceptional clinical success of the On-X valve results from numerous innovations that distinguish it from all other prosthetic heart valves. The design maximizes benefit for the patient and mitigates many of the problems associated with valve prostheses.

PROACT: In January of 2006, the FDA approved the first and only IDE (Investigational Device Exemption) lowered anticoagulation trial for a mechanical valve to be conducted at 40 sites in the United States for the On-X Prosthetic Heart Valve.

Every aspect of the On-X valve plays a role in maximizing benefits for the patient. The scope of innovations in the design reflects the MCRI’s commitment to perfection in creating the On-X Prosthetic Heart Valve.
