Intended Use

The MicroPlex Coil System (MCS) 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 very high risk for management by traditional operative techniques or inoperable.

Device Story

MicroPlex Coil System (MCS) consists of implantable platinum coils attached to fluid-injection delivery pusher; includes peel-away introducer sheath for microcatheter insertion. Used by neurosurgical teams in clinical settings for endovascular treatment of intracranial aneurysms. Complex coils establish initial aneurysm framework; helical coils provide additional filling. Delivery pusher features variable stiffness tube and retention sleeve for coil deployment. Device enables minimally invasive embolization, offering an alternative for patients deemed high-risk for traditional operative techniques.

Clinical Evidence

Bench testing only; performance data included tensile strength, coil detachment, and simulated use testing.

Technological Characteristics

Implantable platinum coils; fluid-injection delivery pusher with variable stiffness tube and retention sleeve; peel-away introducer sheath. Available in 18- and 10-compatible systems for use with 10-, 14-, and 18-type microcatheters. Sterile.

Indications for Use

Indicated for embolization of intracranial aneurysms in patients considered high-risk for traditional surgery or inoperable due to aneurysm morphology, location, or general medical condition.

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).

|-------------------------|--------------------------------------------------------------|
| Common/Usual Name: | Embolization Coil |
| Classification Name: | Device, Artificial Embolization |

#### (4) Device Description

The MicroVention MicroPlex Coil System (MCS) consists of an implantable coil attached to a fluid injection delivery system called a Delivery Pusher. The Delivery Pusher consists of a variable stiffness tube with a retention sleeve that attaches the pusher to the implantable coil. A peel-away introducer sheath assists in the delivery of the implantable coil into the microcatheter.

The MicroPlex Coil System (MCS) is provided in two basic coil configurations, complex and helical. The MCS-CC-2D and MCS-CC-1D are platinum complex coils that establish the initial framework in the treatment of vascular abnormalities (e.g., intracranial aneurysms). The MCS-HC-R, MCS-HC-S and MCS-HC-SX are platinum helical coils that provide additional filling once the initial framework has been established by one or more complex coils. The complex and helical coils are provided in a number of diameters and lengths.

{1}------------------------------------------------

K021914 (P.2 of 2)

The complex and helical coils are available in 18- and 10-compatible systems. The 18compatible systems may be delivered through 14- and 18-type micro-catheters. The 10compatible systems may be delivered through 10- and 14-type micro-catheters.

#### (5) Indications for Use

The MicroPlex Coil System (MCS) 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 very high risk for management by traditional operative techniques or inoperable.

#### Name of Predicate or Legally Marketed Device (6)

The MicroPlex Coil System (MCS) with the MCS-HC-SX helical coil is substantially equivalent to the MicroPlex Coil System (MCS) that was determined to be substantially equivalent on October 29, 2001 (reference K012145).

#### (7) Technological Characteristics and Substantial Equivalence

The MicroPlex Coil System (MCS) with the MCS-HC-SX helical coil is substantially equivalent in operating principle, method of applications for use, design, packaging and sterilization to the predicate device.

#### (8) Performance Data Summary

Performance testing including tensile strength, coil detachment and simulated use demonstrated that the MicroPlex Coil System (MCS) with the MCS-HC-SX helical coil has equivalent performance to the predicate device.

Dear Mr. Cutarelli:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls.
