Research Industries, 6864 S. 300 West, has introduced a "normothermic" or "warm heart surgery" heart muscle preservation catheter at the annual meeting of the American Association of Thoracic Surgeons in Washington, D.C.

For the first time, the catheter provides surgeons with a safe and convenient technique for improving heart muscle preservation during open-heart surgery using normothermic, or normal body temperature, infusions of blood and potassium.Gary L. Crocker, president, said that based on the recently published results of initial clinical use in more than 200 patients, the new normothermic preservation technique using the catheter appears to significantly improve heart muscle recovery after surgery, reducing the need for postoperative cardiac support systems such as intra-aortic balloon pumps and ventricular assist devices.
