No
The description focuses on the mechanical and electrical aspects of the device (coil detachment via electrolysis, power supply controlling current and detecting detachment) and does not mention any AI/ML components or functions.
Yes
The device is described as "embolizing certain intracranial aneurysms" and "embolizing other vascular malformations," which indicates it is used for medical treatment or therapy.
No
The device is an embolization coil system used to treat aneurysms and vascular malformations by occluding them, which is a therapeutic rather than a diagnostic function.
No
The device description clearly outlines multiple hardware components including the coil, delivery wire, power supply, cables, and electrode. While the power supply has software to control detachment, the device is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device used for embolizing vascular structures within the body (intracranial aneurysms, arteriovenous malformations, arteriovenous fistulae, and peripheral vasculature). IVDs are designed to examine specimens from the body (like blood, urine, tissue) to provide information about a person's health.
- Device Description: The device description details a system for delivering and detaching a coil inside the patient's anatomy. This is an interventional procedure, not an in vitro diagnostic test.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any of the typical components or processes associated with in vitro diagnostics.
The Guglielmi Detachable Coil (GDC) is a therapeutic medical device used for embolization procedures.

Intended Use / Indications for Use
The Guglielmi Detachable Coil (GDC) is intended for embolizing certain 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) inoperable,
and for embolizing other vascular malformations such as arteriovenous malformations and arteriovenous fistulae of the neurovasculature.
The GDC is also intended for arterial and venous embolizations in the peripheral vasculature.

Device Description
The GDC system consists of
- GDC power supply
- GDC occlusion coil attached to a delivery wire
- set of GDC connecting cables
- patient return electrode
- two 9-volt batterics
each of which is sold separately.
The occlusion coil is detached by electrolytically dissolving a small portion of the delivery wire upon desired placement of the coil in the anatomy.
GDC occlusion coils are manufactured from platinum wire which is first wound into a primary coil and then formed into a secondary helical shape.
Coils are attached to a delivery wire, which consists of a ground stainless-steel core wire with a stainless-steel coil welded at the distal end and a Teflon® outer jacket. The delivery wire is similar to that employed for the predicate GDC devices cleared variously under K991139, K001183 and K030475.

§ 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).

Intended Use
GDC Power Supply
Boston Scientific Neurovascular's Guglielmi Detachable Coil (GDC) Power Supply is intended for use with all versions of Boston Scientific Neurovascular's Guglielmi Detachable Coils in the embolization of intracranial aneurysms and other vascular malformations of the neuro and peripheral vasculature.
Guglielmi Detachable Coil
The Guglielmi Detachable Coil (GDC) is intended for embolizing certain 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) inoperable,
and for embolizing other vascular malformations such as arteriovenous malformations and arteriovenous fistulae of the neurovasculature.
The GDC is also intended for arterial and venous embolizations in the peripheral vasculature.
Device Description
The GDC system consists of
- · GDC power supply
- · GDC occlusion coil attached to a delivery wire
- · set of GDC connecting cables
- · patient return electrode

The GDC Power Supply is a battery-operated, self-contained unit designed to initiate and control the electrolytic detachment of a GDC coil inside an aneurysm.
Each time the power supply is turned on, the unit defaults to the 1.0 mA current setting. Pressing the "Current" switch one time changes the setting to the .05 mA current setting; pressing a second time changes the setting to 0.75 mA; pressing a third time returns the unit to the default 1.0 mA setting. Each time the switch is pressed, the current display flashes the new current setting.
The GDC Power Supply is designed to apply a constant current through the GDC System and to detect when coil detachment has occurred. It maintains a constant current by:
-
- sensing the amount of resistance to current flow through the GDC System, and
-
- adjusting the voltage needed to maintain the desired current setting. It is also designed to identify subtle changes in the way current is flowing through the GDC System and to recognize those changes which indicate detachment.
Once those patterns are identified, the GDC Power Supply signals detachment and stops the flow of current through the GDC System.
Accessories Description
Accessories consist of the following:
- · Two connecting cables, one black (274 cm long), the other red (152 cm long)
- Two standard 9 volt alkaline batteries
