The description focuses on the physical construction and mechanical function of the coil and delivery system. There is no mention of AI or ML in the intended use, device description, or performance studies.
Yes
The device is intended for the endovascular embolization of intracranial aneurysms and other neurovascular abnormalities, which is a therapeutic intervention aimed at treating medical conditions.
No
The device is an embolization coil used for therapeutic treatment of intracranial aneurysms and other neurovascular abnormalities, not for diagnosis.
No
The device description clearly details physical components made of platinum alloy, stainless steel, parylene polymer, Teflon, and Nickel-Titanium, along with a battery-operated power supply for detachment. This indicates a hardware-based medical device, not a software-only one.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the endovascular embolization of intracranial aneurysms and other neuro vascular abnormalities. This is a therapeutic procedure performed directly on the patient's body.
- Device Description: The device is a physical coil designed to be implanted within blood vessels.
- Lack of Diagnostic Function: The device does not perform any tests on biological samples (like blood, urine, or tissue) to diagnose a condition. Its purpose is to treat a condition by blocking blood flow.
IVD devices are used in vitro (outside the body) to examine specimens from the human body to provide information for diagnosis, monitoring, or screening. This device is used in vivo (inside the body) for treatment.

Intended Use / Indications for Use
The Sapphire™ Detachable Coils are intended for the endovascular embolization of 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 a) very high risk for management by traditional operative techniques, or b) be inoperable. The Sapphire™ Detachable Coils are also intended for the embolization of other neuro vascular abnormalities, such as, arteriovenous malformations and arteriovenous fistulae.

Device Description
The Sapphire" NXT Detachable Coil is manufactured from a platinum alloy wire which is first wound into primary coil and then formed into a secondary three-dimensional structure, which forms helical and spherical shapes. The coil is coated with parylene polymer material. The embolization coil is laser welded to the detachment element made of stainless steel. The detachment element is then laser welded to the delivery wire assembly, which consists of a stainless steel wire and a radiopaque positioning coil that is partially covered with Teflon. The positioning coil provides visual indication under fluoroscopy for positioning of the embolization coil.
In the case of fibered coils, nylon fiber bundles are secured into the primary coil at regular intervals on the coil length.
The tension safe coil is manufactured with an inner filament made of a Nickel-Titanium.
The coil is detached by the battery operated power supply (NDS), which dissolves a small detachment element between the emboliozation coil and the positioning wire.

§ 882.5950 Neurovascular embolization device.
(a)
Identification. A neurovascular embolization device is an intravascular implant intended to permanently occlude blood flow to cerebral aneurysms and cerebral ateriovenous malformations. This does not include cyanoacrylates and other embolic agents, which act by polymerization or precipitation. Embolization devices used in other vascular applications are also not included in this classification, see § 870.3300.(b)
Classification. Class II (special controls.) The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance Document: Vascular and Neurovascular Embolization Devices.” For availability of this guidance document, see § 882.1(e).
