The TEMED Gas Diffuser is a single-use surgical device designed to deliver CO₂ into the surgical field during open-heart procedures. By flooding the operative field with CO₂, the device is intended to displace ambient air and support the surgeon’s de-airing strategy during critical stages of cardiac surgery. Because CO₂ is substantially more soluble in blood and tissue than air, residual CO₂ emboli can be absorbed more rapidly than air emboli. CO₂ is also denser than air, allowing it to settle within the operative field and support a CO₂-rich environment around the heart and great vessels. Designed specifically for cardiovascular surgery, the TEMED Gas Diffuser provides a focused approach to CO₂ field flooding and complements established surgical de-airing techniques.
