Substantial equivalence determined via bench testing, including shelf-life, particulate, biological (ISO 10993-1), small-bore connector (ISO 80369-7/20), trackability, torque, kink resistance, tensile strength, packaging (ISO 11607-1), sterilization, rotational safety, and simulated use testing.

Technological Characteristics

System includes handpiece, locking aspiration syringe, and catheter. Materials evaluated per ISO 10993-1. Mechanical actuation via handpiece-driven rotation of catheter tip. Connectivity: manual mechanical interface. Sterilization per AAMI/ISO standards. Small-bore connectors compliant with ISO 80369-7/20.

Indications for Use

Indicated for the removal of soft emboli and thrombi from vessels in the peripheral vasculature.

Dear Kelli Anderson:

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. 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 located 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.

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

{1}------------------------------------------------

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) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; 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).

### (a)(4). Device Description

The ROVO Mechanical Thrombectomy Device is indicated for the removal of soft emboli and thrombi from vessels in the peripheral vasculature. It consists of a ROVO Driver, a ROVO Locking Aspiration Syringe, and a ROVO Catheter. The ROVO Driver handpiece was designed to work with an off-the-shelf catheter manufactured by Merit Medical Systems, Inc (K121051 and K132409) and an off-the-shelf locking aspiration syringe (K163597) also manufactured by Merit Medical Systems, Inc. Both the catheter and syringe are private labeled with the ROVO system name.

The ROVO Catheter is maneuvered under fluoroscopic observation to the location of the target thromboemboli utilizing the surgeon's preferred vascular access procedure. Once in the desired location, the ROVO Driver handpiece with the ROVO Locking Syringe is attached to the catheter. Squeezing of the handpiece rotates the distal tip of the ROVO Driver. This rotation ensures the thromboemboli is loosened and the catheter tip is fully exposed to the vessel to completely capture and aspirate the thromboemboli. Rotation does not happen when the trigger is released. Aspiration of the emboli/thrombi happens upon release of the Locking Syringe, independent of the catheter rotation. During aspiration, the surgeon can continue to pull the trigger and move the catheter as needed to capture the target thromboemboli.
