ESMR therapy is a new non-invasive therapy approach using Extracorporeal Shockwave technology for Myocardial Revascularization. Ischemic myocardial areas no longer accessible by conventional revascularization therapies could be treated with the Cardiospec ESMR therapy to relieve symptoms resulted from the myocardial ischemia. The treatment is performed using a shockwave generator that is designed to address the unique clinical-anatomical requirements of the chest cavity.
