Intended Use

The AZUR Peripheral Coil System is intended to reduce or block the rate of blood flow in vessels of the peripheral vasculature. It is intended for use in the interventional radiologic management of arteriovenous malformations, arteriovenous fistulae, aneurysms, and other lesions of the peripheral vasculature.

Device Story

AZUR Peripheral Coil System - Detachable 18 consists of platinum alloy coils in helical structures. Coils are attached to a delivery pusher; a battery-powered detachment controller triggers release. Used in interventional radiology to reduce or block blood flow in peripheral vessels (e.g., aneurysms, AVMs, fistulae). Delivered via microcatheter (min 0.021" ID). Physician operates device under fluoroscopic guidance to embolize target lesions, potentially reducing blood flow to pathological vascular structures.

Clinical Evidence

Bench testing only. No clinical data presented. Testing included dimensional measurement, tracking, repositioning/deployment, and detachment tests, all of which met established criteria.

Technological Characteristics

Platinum alloy helical coils; delivery pusher; battery-powered detachment controller. Compatible with microcatheters (min 0.021" ID).

Indications for Use

Indicated for patients requiring reduction or blockage of blood flow in peripheral vasculature, specifically for the interventional radiologic management of arteriovenous malformations, arteriovenous fistulae, aneurysms, and other peripheral vascular lesions.

Regulatory Classification

Identification

A vascular embolization device is an intravascular implant intended to control hemorrhaging due to aneurysms, certain types of tumors (e.g., nephroma, hepatoma, uterine fibroids), and arteriovenous malformations. This does not include cyanoacrylates and other embolic agents, which act by polymerization or precipitation. Embolization devices used in neurovascular applications are also not included in this classification, see § 882.5950 of this chapter.

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 § 870.1(e).

Predicate Devices

## Device Description

The AZUR Peripheral Coil System - Detachable 18 Coils are designed in the helical structure in various diameter and lengths. The coils are comprised of platinum alloy that are wound around the mandrels to form into the helical shape. The implant segment is then attached to the delivery pusher. The pusher is inserted into detachment controller which when activated detaches the coil from the delivery pusher. The detachment controller utilizes battery power to detach the coils from the delivery pusher. The coils are specified to be delivered through a microcatheter with a minimum inner diameter of 0.021" (0.053 mm).
