The NumenFR detachment system is a sterile, handheld, single-patient use device designed for use with the Numen SILK coil embolization system and is operated by two pre-loaded batteries. The analysis of the Numen SILK coil embolization system will occur prospectively if it is determined the patient meets the enrollment criteria. All patients enrolled in the study will receive supportive and medical treatment by choice of the treating physician and in accordance with standard of care. Such treatment includes but is not limited to: neurointensive care, neuromonitoring, and surgical and medical management of cSDH.
