Intended Use

Numen™ Coil Embolization System is intended to endovascularly obstruct or occlude blood flow in vascular abnormalities of the neurovascular and peripheral vessels. Numen™ Coil Embolization System is indicated for endovascular embolization of: - Intracranial aneurysms - Other neurovascular abnormalities such as arteriovenous malformations and arteriovenous fistulae - Arterial and venous embolizations in the peripheral vasculature NumenFR™ Detachment System is intended for use with MicroPort NeuroTech Numen™ Coil Embolization System in the embolization of intracranial aneurysms and other vascular abnormalities of the neuro and peripheral vasculature.

Device Story

Numen Coil Embolization System consists of introducer sheath, pusher, and coil implant; used for endovascular occlusion of vascular abnormalities. NumenFR Detachment System is a sterile, handheld, battery-powered device used to trigger electrolytic detachment of the coil implant. Operated by physician in clinical setting. Coil delivery involves advancing pusher through microcatheter to target lesion; once positioned, NumenFR unit is connected to pusher; pressing detachment button initiates electrolytic process to release coil. System provides permanent occlusion of blood flow to treat aneurysms/malformations. Benefits include minimally invasive treatment of neurovascular/peripheral vascular abnormalities.

Clinical Evidence

No clinical data. Evidence consists of bench testing (visual inspection, dimensional verification, simulated use, fatigue, detachment reliability, friction force, kink resistance, torque strength, radiopacity, particulate testing, coil deformation, tensile strength, corrosion resistance per ASTM F2129, MR compatibility per ASTM F2119/F2213/F2052), sterilization validation, and GLP animal study (canine model) to evaluate in vivo performance. Biocompatibility testing per ISO 10993 series (cytotoxicity, sensitization, irritation, acute toxicity, pyrogenicity, hemocompatibility, genotoxicity, implantation, subchronic toxicity).

Technological Characteristics

Coil: Pt (92%)/W (8%) wire, polypropylene stretch-resistant thread. Pusher: SS 304 hypotube. Introducer: HDPE. Detachment: Electrolytic, powered by two 1.5V AAAA alkaline batteries. Max output 28V DC, 1.8mA. Sterile, single-use, EtO sterilized. MR conditional.

Indications for Use

Indicated for endovascular embolization of intracranial aneurysms, other neurovascular abnormalities (arteriovenous malformations, arteriovenous fistulae), and arterial/venous embolizations in peripheral vasculature.

#### Biocompatibility

The coil implant of the Numen ™ Coil Embolization System is classified as permanent implant in contact with circulating blood >30 days contact duration.

The delivery system including the pusher and introducer sheath of the Numen ™ Coil Embolization System, is classified as externally communicating device in contact with circulating blood < 24 h contact duration.

Refer to the table above for the biocompatibility testing of the coil system.

#### NumenFRTM Detachment System

Performance testing of the NumenFRTM Detachment System consisted of the following:

- Functional performance testing to assess proper operation of the NumenFRTM . Detachment System at start-up and during the detachment process when used in combination with MicroPort NeuroTech Numen™ Coil Embolization System.
- . Software verification in accordance with IEC 62304:2015 Ed. 1.1 and risk assessment conducted in accordance with ISO 14971:2007/(R) 2010.
- . Electrical Safety Testing and EMC Testing in accordance with AAMI/ANSI ES 60601-1:2005, IEC 60601-1-2:2014 Ed. 4 and IEC 60601-1-6 Ed.3.1.

{12}------------------------------------------------

- The subject device is sterilized with Ethylene Oxide. The sterility assurance level . (SAL) of at least 10-6 is assured by using a validated sterilization method per ISO 11135:2014.
- . The device is labeled with two years (2) shelf life, which is supported by accelerated aging shelf-life study.

#### 5. Conclusion

Based on the similarities of the intended use/indications for use, technological and functional characteristics and the results of the non-clinical performance testing, the subject devices, the Numen™ Coil Embolization System and NumenFR™ Detachment System, are substantially equivalent to the legally marketed predicate devices.
