Intended Use

The Hilal Embolization MicroCoils™ are intended for arterial and venous embolization in the peripheral vasculature.

Device Story

Hilal Embolization MicroCoils are platinum wire coils with nylon fibers; designed for arterial and venous embolization in peripheral vasculature. Device delivered via microcatheters (0.018-0.025 inch end hole diameter) using a loading cartridge and stylet. Available in straight, single-curl, and multiple-curl configurations; embolus lengths 0.5-6.0 cm; diameters 2-10 mm. Used by physicians in clinical settings to achieve vessel occlusion. Device functions as a mechanical embolization agent; provides physical obstruction to blood flow. MR Conditional status confirmed via testing.

Clinical Evidence

Bench testing included wire tensile testing and coil uniaxial tensile strength testing. Animal testing (acute porcine model) evaluated straight and single-curl coils, demonstrating no arterial damage or coil migration. Performance, MRI, and biocompatibility testing leveraged from Nester® and Tornado® Embolization Coils (K153778).

Technological Characteristics

Materials: platinum wire, nylon fibers. Configuration: straight, single-curl, multiple-curl. Delivery: pushable via microcatheter (0.018-0.025 inch). Dimensions: 0.5-6.0 cm length, 2-10 mm diameter. MR Conditional. Sterilization: not specified.

Indications for Use

Indicated for arterial and venous embolization in the peripheral vasculature for patients requiring vascular occlusion.

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).

## III. PREDICATE DEVICE

The device subject of this submission is considered substantially equivalent to the predicate device, the Cook Retracta® Detachable Embolization Coil (K123712/K151676), which has never been subject to a design-related recall.

## IV. DEVICE DESCRIPTION

Hilal Embolization MicroCoils™ are manufactured from coiled platinum wire with equidistantly spaced nylon fibers and are available in straight, single-curl, and multiplecurl configurations. The Hilal coils are designed to be delivered by microcatheters with a minimum end hole diameter of 0.018 inch. The extended embolus lengths of the finished device range from 0.5 to 6.0 centimeters. The coiled embolus diameters range from 2 to 10 millimeters. The Hilal coils are loaded in a straight configuration into a loading cartridge. A loading stylet is also provided for loading this coil into the delivery catheter.

# V. INDICATIONS FOR USE

The Hilal Embolization MicroCoils™ are intended for arterial and venous embolization in the peripheral vasculature.

# VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The subject device, the Hilal Embolization MicroCoils™, and the predicate device, the Retracta® Detachable Embolization Coil (K123712/151676), are substantially equivalent in that these devices have identical intended uses and similar technological characteristics. The predicate device is a combined embolization coil and delivery wire. Its embolization coil (made of platinum wire and nylon fibers) is delivered by a detachment mechanism. The subject device is a pushable embolization coil (also made of platinum wire and nylon fibers) delivered with a wire guide through a delivery catheter. The predicate coils (intended for delivery through catheters with an end hole size of 0.035 inch) have a helical shape and are available in lengths of 7 cm or 14 cm and diameters ranging from 4 to 20 mm. The subject Hilal coils (intended for delivery through catheters with end hole sizes of 0.018 through 0.025 inch) have straight, singlecurl, and multiple-curl shapes and are available in lengths ranging from 0.5 to 6 cm and in diameters ranging from 2 to 10 mm. Additionally, the subject device, like the predicate device, is labeled as MR Conditional. However, there are differences in the MR scanning conditions to reflect the testing performed on the subject device. Based on the comparison of the design, intended use, materials, fundamental technology, and principle of operation, the subject device is considered to be substantially equivalent to the currently marketed predicate device.

## VII. PERFORMANCE DATA

The subject device underwent the applicable testing listed below to ensure reliable design and performance under the testing parameters.

- . Wire Tensile Testing - Testing shows the raw wire has a peak load value greater than or equal to the minimum tensile strength requirements. The predetermined acceptance criteria were met.
- Coil Tensile Testing - Testing characterized the embolization coils' uniaxial tensile strength.
- . Animal Testing – An acute performance study was performed in a porcine model on straight and single curl Hilal coils, showing no evidence of arterial damage or coil migration. The predetermined acceptance criteria were met.

Other testing was leveraged from the 510(k) submission for Nester® and Tornado® Embolization Coils (K153778). Performance (bench, MRI, and animal) and biocompatibility testing was conducted in accordance with applicable FDA guidance documents to confirm the reliable performance of critical device characteristics.

# VIII. CONCLUSIONS

The data included in this submission indicate that the subject device does not raise new questions of safety or effectiveness compared to the predicate device. This supports a determination of substantial equivalence.
