Release principle of embolic spring coil

Principle: When the coil is stable in the aneurysm cavity, loosen the connection between the push rod and the coil, pull out the push rod from the microcatheter, and then prepare to send the next coil. Embolization of cerebral aneurysm by minimally invasive way, filling the coil into the tumor to form thrombus to stop blood flow and reduce the pressure in the tumor, thus reducing the possibility of tumor rupture.
