More Information

None

No
The device description focuses on the physical characteristics of the needle and its use under ultrasound guidance, with no mention of AI or ML for image analysis, decision support, or any other function.

No
This device is a needle used for administering regional anesthetic blocks, which is a procedural tool rather than a therapeutic device that directly treats a disease or condition. Its purpose is for drug delivery.

No
The device is a needle used for administering regional anesthetic blocks, not for diagnosing conditions. Its primary function is therapeutic/interventional.

No

The device description clearly outlines physical components like a luer hub, stainless steel cannula, and polyethylene sheath, indicating it is a hardware device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. They are used outside of the body.
  • Device Description: The EchoGlo™ Peripheral Nerve Block Needle is a physical needle designed to be inserted into the body for the administration of regional anesthetic blocks. It is used in vivo.
  • Intended Use: The intended use is for administering anesthetic blocks, which is a medical procedure performed directly on a patient.

The device is a surgical/procedural instrument, not a diagnostic tool that analyzes samples.

Dear Michael Johnson:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal

1

statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

5. SUBSTANTIAL EQUIVALENCE DISCUSSION

Indications for Use

The Echoglo indications for use is similar to the predicate devices include enhanced for ultrasound visibility, similar transient delivery and the option to facilitate placement of a catheter.

A. Both the subject and predicate devices are enhanced for ultrasound visibility. The EchoGlo™ needles are enhanced for ultrasound visibility via grooved echogenic feature. The EchoGlo™ needles also have visible bands which identify the needle length and needle insertion depth in 1cm increments after echogenic feature, visible to the eye without ultrasound imaging.

B. Both the subject and predicate devices offer similar transient use.

C. Both the subject and predicate devices offer the option to facilitate placement of a catheter. Testing demonstrating equivalency for placement.

Summary of Technology Characteristics

The Smiths Medical EchoGlo Peripheral Nerve Block Needles and predicate devices are both designed for enhanced ultrasound visibility, delivery of regional anesthesia, and to facilitate placement of a catheter. The Smiths Medical EchoGlo™ Peripheral Nerve Block Needles has similar technological characteristics as the predicate device. Both subject and predicate device incorporate 1cm incremented visible depth markings to monitor insertion depth through ultrasound imaging. The subject device and predicate devices are prescribe by physician only, for single use and provided Ethylene Oxide (EO) sterile to the healthcare facility and/or end user.

The difference between the predicate is the Smiths EchoGlo has echogenic visible bands with helical markers while the SonoTAP and Tuohy Sono include diamond shape markers. Additionally, the Echoglo offers a Bevel tip in 20G-22G, and a Tuohy tip in 18G.

predicate device based on comparisons of the device classifications, intended use, and technological characteristics. Verification and validation tests confirmed the suitability of the subject devices for its intended uses. The results of biocompatibility testing and performance confirmed the substantial equivalence of the EchoGlo™ Peripheral Nerve Block Needle. The test results do not raise different safety or performance questions, and confirmed that the EchoGlo™ Peripheral Nerve Block Needle is substantially equivalent to the predicate devices.
