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).

### Device Description:

The Optima Coil System is a series of specialized coils that are inserted into the vasculature under angiographic visualization to embolize intracranial aneurysms and other vascular anomalies. The system consists of an embolization coil implant comprised of platinum and tungsten, affixed to a delivery pusher 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 detached from the delivery pusher in a serial manner until the aneurysm is occluded.

#### Indications for Use:

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

#### Intended Use:

The Optima Coil System is intended for use in the peripheral and neuro-vasculature to endovascularly obstruct or occlude blood flow in vascular abnormalities of the neurovascular and peripheral vessels.

The modified Optima Coil System and the predicate Optimal Coil System differ in the following:

- Addition of new sizes of the coil implant. ●
- Addition of new combinations of coil OD, filar diameter, secondary shape diameter and ● lengths.

The differences between the subject and predicate devices do not raise new questions of safety and effectiveness.

#### Performance Data - Bench:

The following non-clinical bench testing was performed to evaluate the device changes and to demonstrate substantial equivalence of the modified Optima Coil System to the predicate device:

| Test | Acceptance Criteria | Results |
|--------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------|
| Visual Inspection, Dimensional<br>Inspection, and Resistance Check | The test samples shall meet established test<br>acceptance criteria for visual physical<br>damage and secondary diameter and length. | Pass |
| Simulated Use | The test samples shall be prepared in<br>accordance with the instructions for use and<br>meet established test acceptance criteria for<br>device performance in a clinically relevant<br>model. | Pass |
| Stretch Resistance | The samples shall meet established test<br>acceptance criteria for tensile strength. | Pass |

#### Conclusion:

There is no change to the intended use, materials, principles of operation or performance requirements of the modified Optima Coil System in comparison to the predicate device (K200030). The successful completion of non-clinical bench testing demonstrates that the modified Optima Coil System is substantially equivalent to the predicate device.
