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 8F Guide Catheter is indicated for the introduction of intravascular catheters into the peripheral, coronary, and neuro vasculature.

## Device Description

The Radical the Dude 8F Guide Catheter (Dude 8F Catheter) is an 8 French (Fr) guide catheter designed to aid the physician in accessing the target vasculature during interventional procedures. The Dude 8F Catheter has a usable length between 80 cm and 110 cm, and an outer diameter (OD) size designation of 8 Fr. The Dude 8F 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 8F Catheter has a hydrophilic coating. The Dude 8F Catheter is packaged with a rotating hemostasis valve (RHV) and a peel-away sheath.

## Principles of Operation

The Radical the Dude 8F 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 8F 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 8F Catheter is advanced through the vasculature. Use of the Dude 8F Catheter relies on standard percutaneous interventional techniques,

### Biocompatibility

The subject Radical the Dude 8F 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. The subject device uses the same materials and manufacturing processes as the predicate device. Therefore, based on risk analysis, the following tests were performed to confirm biocompatibility of the subject device (Table 3).

{9}------------------------------------------------

| Tests | Output | Result | Conclusion |
|---------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------|----------------------------------------------------|
| Hemocompatibility:<br>Partial Thromboplastin Time (PTT) | The test article average clotting time<br>was higher and was not statistically<br>significant when compared to the<br>negative control.<br>The test article average clotting time<br>was lower and was not statistically<br>significant when compared to the<br>vehicle control. | Pass | PTT similar to the<br>reference device. |
| Thrombogenicity in Canine Model | An in vivo canine test to evaluate<br>the thrombogenic potential of the<br>subject device compared to a<br>comparator device. | Pass | Thrombogenicity<br>similar to reference<br>device. |

## 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.

## Sterilization and Shelf Life

The Radical the Dude 8F Guide Catheter is sterilized using a validated ethylene oxide (EO) process with a sterility assurance level of 1x106. The sterilization method is identical for the subject and predicate devices.

The subject device's shelf life and packaging configuration remain identical to that of the predicate device. Therefore, no shelf life testing or packaging validation was deemed necessary to support the device and packaging shelf life.

## Clinical Study

The non-clinical performance and biocompatibility testing were determined to be sufficient to support the substantial equivalence of the subject device.

## Conclusion

The subject Radical the Dude 8F 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 and biocompatibility testing demonstrates that the Dude 8F Guide Catheter is substantially equivalent to the predicate device.
