What is it indicated for?

The MicroPlex Coil System (MCS) and Hydrocoil Embolic System (HES) with the HydroLink Syringe Kit are intended for embolization of those intracranial aneurysms that - because of their morphology, their location, or the patient's general medical condition - are considered by the treating neurosurgical team to be very high risk for management by traditional operative techniques or inoperable. The MCS and HES are also intended for embolization of other neuro-vascular abnormalities such as arteriovenous malformations and arteriovenous fistulae and for arterial and venous embolizations in the peripheral vasculature.

Indications for use as stated in the FDA summary.
