A Heart and Lung Machine
Thank you for visiting the web page for the McLeod Aerating Caridac (MAC) pump, an extracorporeal perfusion device (otherwise known as a heart and lung machine). The design for this device, originally invented in the late 1950’s but now unpatentable because it was fully disclosed then, is now being offered to any company, charitable or profit-seeking, for production and distribution without charge. Our hope is that this machine, which is much smaller and cheaper than the current industry standard, will be used in foreign, undeveloped nations where such concerns prevent good medical care from being widely available. If you have any questions about this device or implementing it, please e-mail us below. Thank you very much.
