GDC Coils (All Versions except GDC 18-Fibered VortX™ Shape): The Guglielmi Detachable Coil is intended for embolization of those 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. The GDC is also intended for embolization of other neurovascular abnormalities such as arteriovenous malformations and arteriovenous fistulae. GDC 18-Fibered VortX Shape: This product is intended for embolization of vascular abnormalities such as arteriovenous malformations and arteriovenous fistulae of the neuro vasculature. GDC-18 Fibered VortX Shape is also intended for arterial and venous embolizations in the peripheral vasculature.
Device Description
Guglielmi Detachable Coils (GDC®) are used as part of a system indicated for endovascular occlusion in patients with high surgical risk intracranial aneurysms and other neurovascular abnormalities. The GDC system consists of the following items, each of which is sold separately - · GDC Power Supply - · GDC SynerG TM occlusion coil attached to a delivery wire - · set of GDC connecting cables - · patient return electrode - · two 9-volt batteries GDC SynerG coils are available in regular (secondary helical), 2D (secondary helical with distal helix) and 3D (tertiary) shapes, in a range of sizes, and in Standard, Soft and Stretch Resistant versions, all of which are compatible with Boston Scientific Target Infusion Catheters with two tip markers. GDC is also available as an UltraSoft™ Coil, developed to address physicians' requests for a softer Stretch Resistant coil and a wider range of coil sizes to treat intracranial aneurysms. Boston Scientific Target also offers a Fibered GDC device, GDC 18-Fibered VortX Shape, incorporating synthetic fibers through the main coil for a more rigid coil. All of the coils are manufactured from a platinum-tungsten alloy wire which is wound into a primary or main coil. Depending upon the desired final configuration, a coil is either formed into a secondary helical shape (standard and Stretch Resistant GDC), vortex shape (GDC-18 Fibered VortX) or tertiary shape (3D GDC). The distal tip of the coil is welded to form a smooth tip (with the exception of Stretch Resistant GDC). The coils are attached to a delivery wire, which consists of a ground stainless-steel core with a stainless-steel coil welded at the distal end and a Teflon® outer jacket. Using fluoroscopic guidance and a guiding catheter to access the lesion, the physician delivers the GDC coil to the targeted site through an infusion catheter. Upon desired placement in the anatomy, the coil is detached by use of a battery-operated power supply designed specifically for use with the GDC system. The GDC SynerG Power Supply used to initiate and control detachment is a self-contained unit that applies a constant current through the GDC system until detachment is detected. Each time the GDC 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 0.5 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. After selecting a current setting and initiating detachment, the current flowing through the delivery wire begins to dissolve, by electrolysis, the exposed stainless steel at the junction with the platinum-tungsten coil. Over a period of several minutes, the exposed steel completely dissolves and the platinum-tungsten coil detaches. When coil detachment is detected, the GDC SynerG Power Supply immediately halts current flow, freezes the displays and emits an audible signal that coil detachment has occurred. Using fluoroscopy, the physician then verifies that the delivery wire can be withdrawn without disturbing the newly placed coil, and can resume electrolysis if necessary. Multiple GDC coils may be placed within a single aneurysm, at the discretion of the interventional team, to achieve optimum occlusion of the lesion.

No
The device description focuses on the mechanical and electrical aspects of the coil and detachment system, with no mention of AI or ML for image analysis, decision support, or any other function.

Yes
The device is described as being used for the embolization of intracranial aneurysms and other neurovascular abnormalities, which are medical conditions that affect the body's structure and function. Embolization is a medical procedure aimed at treating these conditions.

No

The device is an embolization coil used for therapeutic purposes, such as occluding aneurysms or vascular malformations, not for diagnostic imaging or assessment.

No

The device description clearly outlines multiple hardware components including coils made of platinum-tungsten alloy, a delivery wire, a power supply, connecting cables, and a patient return electrode. The function of the device relies on the interaction of these physical components for embolization and detachment.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
  • Device Function: The GDC Coils are used for the physical embolization (blocking) of blood vessels in the brain and peripheral vasculature. This is a therapeutic procedure performed within the body, not a diagnostic test performed on a sample outside the body.
  • Intended Use: The intended use clearly states "embolization of those intracranial aneurysms" and "embolization of other neurovascular abnormalities." This describes a treatment, not a diagnostic process.
  • Device Description: The description details the physical components of the coil system and how it is used to physically block blood flow. It does not mention any analysis of biological samples.

Therefore, the GDC Coils fall under the category of a therapeutic medical device, not an in vitro diagnostic device.
