Intended Use

The Barricade Coil System is intended for the endovascular embolization of intracranial aneurysm and other neurovascular abnormalities such as arteriovenous malformations and arteriovenous fistulae. The Barricade Coil System is also intended for vascular occlusion of blood vessels within the neurovascular system to permanently obstruct blood flow to an aneurysm or other vascular malformation and for arterial and venous embolizations in the peripheral vasculature.

Device Story

Barricade Embolization Coil System consists of platinum/tungsten alloy coils delivered via stainless steel pusher and microcatheter; used for endovascular embolization of intracranial aneurysms and neurovascular/peripheral vascular malformations. Physician inserts coils into target vasculature under angiographic visualization; coils create blood stasis to induce thrombosis and occlude aneurysm. System features electrolytic detachment mechanism controlled by external power supply (ED2-BL) or optional handheld detachment cable. Device facilitates permanent obstruction of blood flow to vascular anomalies, reducing risk of aneurysm rupture or malformation-related complications.

Clinical Evidence

Bench testing only. Verification and validation testing included simulated use, tensile strength testing, packaging integrity, and sterility assurance (SAL 10^-6). Results demonstrated that the modified device with the optional handheld detachment cable performs equivalently to the predicate devices without introducing new safety or performance concerns.

Technological Characteristics

Coils: Platinum/tungsten alloy; 0.010"-0.014" primary diameter; 1.5mm-15mm secondary diameter; complex/helical shapes. Delivery: Stainless steel pusher. Detachment: Electrolytic. Equipment: Detachment Control Power Supply (ED2-BL) and optional handheld detachment cable. Sterile, single-use.

Indications for Use

Indicated for endovascular embolization of intracranial aneurysms, arteriovenous malformations, and arteriovenous fistulae; vascular occlusion of neurovascular blood vessels to obstruct flow to aneurysms or malformations; and arterial/venous embolizations in peripheral vasculature.

Regulatory Classification

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.

Special Controls

*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).

The modified Barricade Embolization Coil System is substantially equivalent in intended use, principal of operation and technological characteristics to the Barricade Embolization Coil System cleared under premarket notifications K123338 and K131475.

# Description of the Device Subject to Premarket Notification:

The Barricade Embolization Coil System (BCS) is a series specialized coils that are inserted into the vasculature under angiographic visualization to embolize intracranial aneurysms and other The system consists of an embolization coil implant comprised of vascular anomalies. platinum/tungsten, affixed to a delivery pusher with an introducer sheath to facilitate insertion into the hub of a microcatheter. The system is available in various shapes, lengths and sizes. The devices are to be placed into aneurysms to create blood stasis, reducing flow into the aneurysm and thrombosing the aneurysm. Upon positioning coils into the aneurysm, the coils are electrolytically detached from the delivery pusher in serial manner until the aneurysm is occluded.

# Indication for Use:

The Barricade Coil System is intended for the endovascular embolization of intracranial aneurysms and other neurovascular abnormalities such as arteriovenous malformations and arteriovenous fistulae. The Barricade Coil System is also intended for vascular occlusion of
