AI/ML Overview

The document provided is a 510(k) Summary for the Radical the Dude 7F Guide Catheter. It describes the device, its intended use, and a comparison to a predicate device to demonstrate substantial equivalence. This document does NOT describe the acceptance criteria and study for an AI/ML powered device.

The Radical the Dude 7F Guide Catheter is a medical device, specifically a guide catheter, and the submitted information pertains to its regulatory clearance as a physical medical device, not an AI/ML software device. As such, the information requested regarding AI/ML device performance (like test set sample size, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth establishment, and training set details) is not applicable or present in this document.

The document mainly focuses on:

  • Bench Testing: Mechanical and material property tests to ensure the device meets engineering specifications and is safe for its intended use.
  • Biocompatibility Testing: To ensure the materials used in the device are safe for contact with the human body.
  • Sterilization: Validation of the sterilization process.
  • Shelf Life and Packaging: Testing to ensure the device maintains its integrity over time.

Therefore, I cannot provide the requested information for an AI/ML device based on this submission.

Dear Janice Kemp:

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.

Indications for Use

The Radical the Dude 7F Guide Catheter is indicated for the introduction of intravascular catheters into the peripheral, coronary, and neuro vasculature.

Device Description

The Radical the Dude 7F Guide Catheter (Dude 7F Catheter) is a 7 French (Fr) guide catheter designed to aid the physician in accessing the target vasculature during interventional procedures. The Dude 7F Catheter has a usable length between 95 cm and 115 cm, and an outer diameter (OD) size designation of 7 Fr. The Dude 7F Catheter has variable stiffness along its length, incorporating hybrid ribbon technologies to maintain stability and vary stiffness along the device length. The distal portion of the Dude 7F Catheter has a hydrophilic coating. The Dude 7F Catheter is packaged with a rotating hemostasis valve (RHV) and a peel-away sheath.

Principles of Operation

The Radical the Dude 7F Guide Catheter may be used with support catheters to assist in accessing target vasculature. During use, the male luer of the RHV is attached to the proximal luer of the Dude 7F Catheter to create a continuous lumen through the catheter and to the RHV ports. The female luer of the RHV is typically connected to a saline drip line while the Dude 7F Catheter is advanced through the vasculature. Use of the Dude 7F Catheter relies on standard percutaneous interventional techniques,

Inside the brain shape, there are several figures with their arms raised, colored in shades of orange, yellow, and purple. Below the brain shape, the word "MADURO" is written in a bold, sans-serif font. The logo appears to represent a concept related to intelligence, collaboration, or community.

Animal Study

An animal study was not deemed necessary to support the substantial equivalence of the subject device to the predicate device. Bench testing was determined sufficient to support substantial equivalence.

Biocompatibility

The subject Radical the Dude 7F Guide Catheter is categorized as a limited exposure (<24 hours), externally communicating device with circulating blood contact in accordance with ISO 10993-1 and FDA guidance, "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process"." The subject device is constructed using materials that are commonly used in the medical device industry.

All patient contacting components of the subject device have been evaluated for biocompatibility using the following tests (Table 3).

Per the completed biocompatibility testing, the requirements and performance specifications for the subject device were met, as the device was shown to be non-cytotoxic, non-irritant, non-toxic, non-pyrogenic, non-hemolytic, and non-thrombogenic.

Sterilization

The subject Radical the Dude 7F Guide Catheter will be sterilized using a validated EO process with a sterility assurance level (SAL) of 106. The validation will be conducted using the overkill method according to ISO 14937:2009 "Sterilization of health care products - General requirements for characterization of a sterilizing agent and the development, validation and routine control of a sterilization process for medical devices."

Shelf Life and Packaging

Accelerated aging testing based on ASTM F1980 was conducted to verify packaged device performance. Accelerated aging equivalent to 1-year of real time shelf life was used to support the 1year shelf-life claim. Device performance was verified by functional and performance testing.

Clinical Testing

A clinical study was not deemed necessary for this submission. Substantial equivalence of the subject device to the predicate has been established through the results of nonclinical testing.

Conclusion

The subject Radical the Dude 7F Guide Catheter has similar intended use, indications for use, principles of operation, and technological characteristics as the predicate device. The technological differences identified do not raise new questions of safety or effectiveness between the subject and predicate devices. Performance testing demonstrates that the Radical the Dude 7F Guide Catheter is substantially equivalent to the predicate device.
