Dear Lori Grace:

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.

### Device Description

The SINC™ (Selective Interventional Navigation Catheter) Support Catheters are single lumen catheters designed to access peripheral vasculature. These catheters are available in a variety of lengths and offer a side port. Each configuration has a braided support matrix and hydrophilic coating on the distal segment of the catheter. The distal tip is clearly distinguished by a radiopaque gold coated tip.

The SINC Support Catheters will also allow for exchange of guidewires and other interventional devices and provide a conduit for delivery of saline solutions or diagnostic contrast.

#### Indications for Use

The SINC™ Support Catheters are intended to be used in conjunction with steerable guidewires to access discrete regions of the peripheral vasculature. They may be used to facilitate placement and exchange of guidewires and other interventional devices and provide a conduit for delivery of saline solutions or diagnostic/ therapeutics agents.

#### Indications for Use Comparison

The SINC™ Support Catheter indications for use are identical to the predicate device indications for use.

# REFLOW MEDICAL

# Technological Comparison

The SINC™ Support Catheter is nearly identical to the predicate device platform (spex LP, K200094). Like the predicate device, the SINC™ Support Catheter is intended for use in the peripheral vasculature to facilitate placement and exchange of guidewires. .

The subject and predicate devices are based on the following identical technological elements:

- all delivered to the target site using an over-the-wire percutaneous technique .
- . all have a through lumen to allow passage and exchange of guidewires
- all have a smooth inner lumen to provide reduced friction for guidewire movement .
- . all have a polymer catheter shaft with specific geometry to control the torque and push movements associated with lesion crossing

The following technological differences exist between the subject and predicate devices:

- The distal tip of the SINC support catheter has been modified to include a side port. ●
# Non-Clinical and/or Clinical Tests Summary & Conclusions

The following performance data were provided in support of the substantial equivalence (reference ISO 10555-1).

- Simulated Use Testing
- Dimensional Verification ●
- Leak Testing
- Bond Integrity
- Component Integrity
- Corrsion Testing
- Kink Resistance
- Torque Testing
- Particulate
- Catheter Flow Rate and Burst Testing
- Lubricity Characterization ●
- Packaging Testing
- Design Validation ●

The SINC™ Support Catheter met all specified criteria and did not raise new safety and performance questions. Based on the performance testing, the SINC™ Support Catheter was found to have a safety and effectiveness profile that is substantially equivalent to the predicate device.
