Guglielmi detachable coil

A Guglielmi detachable coil, or GDC, is a platinum coil commonly used in intracranial minimally-invasive interventions for the occlusion of brain aneurysms, it is a specific variant of endovascular coiling therapy. It was invented by Italian neurosurgeon Dr. Guido Guglielmi in 1990, and was gradually introduced in the later 1990s as an alternative to surgical clipping, which requires invasive surgery. September 1995, the Guglielmi Detachable Coil (GDC) system received formal approval from the Food and Drug Administration (FDA) for treatment of surgically high-risk intracranial aneurysms.
