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
