Fig 1. Line drawing of a Cerecyte coil, consisting of a regular bare platinum coil with PGA running through the lumen of the primary platinum wind of the Cerecyte coil (arrows). This also provides stretch resistance when placing coils into the aneurysm. There is some space between the platinum primary winding of the coil for water to pass inside the loops, leading to hydrolysis of the PGA within the coil.
