Device Story
Percutaneous orbital atherectomy system; removes/reduces occlusive material in peripheral arteries and AV dialysis fistulae. Components: reusable saline pump, single-use orbital atherectomy device (OAD) with physician-operated handle and interchangeable crown cartridge, lubricant, and guide wire. Mechanism: centrifugal force, orbital rotation, differential sanding, and bi-directional sanding via diamond-coated, eccentrically mounted crown. Used in clinical settings by physicians to restore luminal patency. Benefits: removal of stenotic material to improve blood flow.
Clinical Evidence
Bench testing only. Testing included biocompatibility (cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, hemolysis, complement activation, platelet/leukocyte counts, PTT) and bench performance (corrosion resistance, orbit characterization, particulate testing, radiopacity, tensile verification).
Technological Characteristics
Orbital atherectomy system; diamond-coated, eccentrically mounted crown; centrifugal force/orbital rotation mechanism. Components: reusable saline pump, single-use OAD, lubricant, guide wire. Crown styles: solid, classic, micro; sizes: 1.25-2.00mm; driveshaft lengths: 75-200cm. Sterile, single-use.
Indications for Use
Indicated for patients with occlusive atherosclerotic disease in peripheral arteries or occluded hemodialysis grafts (AV shunts) who are candidates for percutaneous transluminal atherectomy or angioplasty.
Regulatory Classification
Identification

Dear Nikita Basandra:
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
{1}------------------------------------------------
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 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 (QS) 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).
