Intended Use

The Focus™ Echogenic Nerve Stimulating Needle is intended for locating and stimulating peripheral nerves and nerve plexuses for nerve block anesthesia techniques using a Peripheral Nerve Stimulator and/or ultrasound guidance.

Device Story

Focus Echogenic Nerve Stimulating Needle; sterile, single-use, FEP-coated stainless steel needle; B-bevel tip. Features black 10 mm marker bands for placement; distal 10 mm dimpled for ultrasound visibility. Insulated wire connects cannula to external peripheral nerve stimulator. Used by clinicians for nerve block anesthesia; facilitates nerve localization via electrical stimulation and ultrasound imaging. Benefits include enhanced needle visualization and precise nerve targeting for anesthesia delivery.

Clinical Evidence

Bench testing only. Verification performed: air/fluid leakage, bond strength (needle-to-hub, wire-to-connector), tensile strength, cannula break strength, penetration force, sterilization, and biocompatibility. Animal model evaluation confirmed electrical current applied via the needle successfully stimulates nerves.

Technological Characteristics

Stainless steel cannula with FEP (fluorinated ethylene propylene) polymer coating; plastic hub; insulated wire for nerve stimulator connection. Distal 10 mm dimpled for ultrasound echogenicity. Available in 22 and 23 gauge. Sterile, single-use.

Indications for Use

Indicated for locating and stimulating peripheral nerves and nerve plexuses for nerve block anesthesia techniques in patients requiring regional anesthesia, utilizing peripheral nerve stimulators and/or ultrasound guidance.

Regulatory Classification

Identification

An anesthesia conduction needle is a device used to inject local anesthetics into a patient to provide regional anesthesia.

Predicate Devices

• EchoStim Facet Tip Needle (K063380)
• Temena Hybrid Nerve Location Needle (K080603)

# 3. Predicate Devices:

Cook Incorporated's Focus Echogenic Nerve Stimulating Needle (hereafter referred to as the Focus Needle) is substantially equivalent to the EchoStim Facet Tip Needle manufactured by Hakko Medical Co., Ltd. of Japan and distributed in the U.S. by Havel's Inc. under 510(k) clearance K063380. The Focus Echogenic Nerve Stimulating Needle is also substantially equivalent to the Temena Hybrid Nerve Location Needle manufactured by TE ME NA under 510(k) clearance K080603.

#### 4. Device Description:

The Focus Needle is a sterile, single use FEP-coated stainless steel needle with a B Bevel tip. The needle contains black marker bands every 10 mm to aid in placement and echogenic dimpling on the distal 10 mm to enhance visibility under ultrasound guidance. An insulated wire is attached to the stainless steel cannula and can be connected to a peripheral nerve stimulator unit. The device will be available in the following gauge sizes: 22 and 23.

## 5. Intended Use:

The Focus™ Echogenic Nerve Stimulating Needle is intended for locating and stimulating peripheral nerves and nerve plexuses for nerve block anesthesia techniques using a Peripheral Nerve Stimulator and/or ultrasound guidance.

{2}------------------------------------------------

## 6. Technological Characteristics:

The Focus Needle consists of a stainless steel cannula coated with a fluorinated ethylene propylene polymer to provide resistance to loss of electrical current along the shaft of the needle, a plastic hub with an attachment point for a connection tube, and an insulated wire attached to the cannula to allow connection to a nerve stimulator unit. Additionally, the distal 10 mm of the needle are dimpled using a pattern designed to enhance visibility by ultrasound. The technological characteristics of the Focus Needle and the two predicate devices, the EchoStim Facet Tip Needle and the Temena Hybrid Nerve Location Needle are substantially equivalent in that all devices are coated with an electrically resistant polymer to allow for electric nerve stimulation, and all devices can be visualized with ultrasound technology. No new technological aspects are being introduced with the proposed device.

To demonstrate reliable design and performance of the Focus Needle, the following verification testing was performed:

- . Air leakage under vacuum,
- . Fluid leakage under pressure,
- Force to remove protector. .
- . Needle to hub bond strength,
- Wire to electrical connector bond, .
- . Wire tensile strength.
- . Wire to hub tensile strength,
- Cannula break strength, .
- . Penetration force,
- Sterilization testing, .
- Biocompatibility testing. .

Additionally, an evaluation in an animal model was carried out to verify that electrical current applied through the Focus Needle by a Peripheral Nerve Stimulator unit can stimulate a nerve.
