Summary
The study is a multi-center prospective, single-arm, post-market study evaluating the efficacy and radiologic and functional outcomes associated use of the Numen SILK coils for Middle Meningeal Artery (MMA) embolization following Chronic Subdural Hematoma (cSDH) compared to surgical evacuation or medical management alone. Chronic subdural hematoma is a collection of blood between the dural mater and the brain. It typically develops over time in older adults or people on anticoagulant medication. Blood slowly accumulates over time and often becomes encapsulated by a fibrous membrane over weeks or months, which can lead to the gradual development of symptoms. Middle Meningeal Artery embolization (MMAE) through coiling provides a minimally invasive option for cSDH treatment and prevention of reaccumulation and recurrence.

Interventions
The Numen SILK coil embolization system is designed to be used in conjunction with the NumenFR detachment system. It consists of two main parts: • Introducer Sheath: The purpose of this sheath is to facilitate the introduction of the coil into the microcatheter. • Coil System: Composed of the pusher and coil implant. The coil is a permanent implant intended to occlude blood flow in vascular abnormalities. The pusher is used to deliver the coil implant to the target lesion. 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
