No.
The document describes a medical device for vascular access, and it does not mention any AI, DNN, or ML components. It focuses on mechanical and biological performance, not computational capabilities.

Yes

The device's intended use explicitly states: "The Merit Prelude Wave Hydrophilic Sheath Introducer is intended to provide access and facilitate the percutaneous introduction of various devices into veins and/or arteries... for a variety of diagnostic and therapeutic procedures." This directly indicates its involvement in therapeutic applications.

No

Explanation: The "Intended Use/Indications for Use" states that the device is intended to "facilitate the percutaneous introduction of various devices into veins and/or arteries... for a variety of diagnostic and therapeutic procedures." The device itself is an introducer, not a diagnostic tool.

No

The device is a physical medical device (a sheath introducer) used to provide access and facilitate the introduction of other devices into blood vessels. The description explicitly details hardware components, materials, and physical performance testing (e.g., tensile strength, pushability, leak test). There is no mention of software being the primary medical device.

No.
The device is a sheath introducer used for accessing veins and/or arteries to facilitate the introduction of other diagnostic or therapeutic devices, not for performing in vitro diagnostic tests on samples from the human body.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Performance testing of the subject Micro Ace™ Gold was conducted based on the risk analysis - and based on the requirements of the following international standards:

  1. ISO 10555-1:2013, Intravascular Catheters – Sterile and single-use catheters – Part 1: General requirements.

  2. EN ISO 11070 2014/A1:2018, Sterile Single-Use Intravascular Catheter Introducers.

Dear Niloufar Samimi:

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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

(https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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 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 (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-devices/medical-device-safety/medical-device-reporting-mdr-how-report-medical-device-problems.

For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/contact-us-division-industry-and-consumer-education-dice) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).

| Comparison to Predicate Device | The design and technological characteristics of the subject modified Prelude Wave are substantially equivalent to those of the predicate Prelude IDEAL. The subject device has the same basic design as the predicate device. The differences between the predicate Prelude IDEAL device and the subject/modified Prelude Wave device are as follows:

• Sheath material.
• Modified sheath/dilator tip and fit.
• Packaged with adhesive backed fixation device to keep the sheath in place throughout the procedure.

The comparison between the subject and the predicate devices is based on the following:

• Same intended use
• Same indications for use
• Same sterilization methods
• Same packaging scheme
• Same fundamental technology/principles of operation
• Similar material types (all meet ISO 10993 biocompatibility requirements)
