ECMO is short for Extracorporeal Membrane Oxygenation. It is a life-support machine that bypasses heart and lung operations. It is the process of removing carbon-dioxide and placing oxygen into the blood. Moreover, ECMO aids in the process of circulating and oxygenating the blood outside the body of the patient.
According to the plot, Endovascular Embolization is an invasive surgical procedure used to treat abnormal blood vessels found in your brain, as well as other areas of your body.

After which, the vessel is sealed with any number of appropriate materials: biologically inert glues (doesn't trigger an immune response), tiny plastic particles, foam, metal coils, or a surgical balloon.
Stereotactic Radiosurgery uses medical imaging [studies] to precisely guide the tip of a delicate instrument such as a needle or beam of radiation onto the site of bodily injury.
