Intended Use

The radial compression device is designed to apply compression in order to achieve temporary hemostasis of the radial artery after a percutaneous transradial procedure.

Device Story

Radial Compression Device (RC-001) is a mechanical vascular clamp used post-percutaneous transradial procedure. Device consists of a plate, turn cap, screw rod, hook and loop band, and cushions. Operator secures band around patient's wrist; square cushion is positioned over puncture site. Turning the screw cap applies localized pressure to the radial artery to achieve hemostasis. Used in clinical settings by healthcare professionals. Device is single-use and sterile. Provides non-invasive mechanical compression to facilitate rapid hemostasis, reducing risk of hematoma or bleeding at the access site.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including visual/dimensional inspections, bond strength, mechanical function (turn cap/screw), packaging/aging, and pressure application testing. Biocompatibility testing (cytotoxicity, sensitization, irritation, acute systemic toxicity, pyrogenicity, hemolysis) and EO sterilization validation (SAL 10^-6) were performed per ISO standards.

Technological Characteristics

Mechanical vascular clamp. Components: plate, turn cap, screw rod, hook and loop band, tapered/square cushions. Sterilization: Ethylene Oxide (EO) per ISO 11135 (SAL 10^-6). Biocompatibility: ISO 10993 compliant. Single-use. No electronic or software components.

Indications for Use

Indicated for patients undergoing percutaneous transradial procedures requiring temporary hemostasis of the radial artery.

Regulatory Classification

Identification

A vascular clamp is a surgical instrument used to occlude a blood vessel temporarily.

Dear Liqin Wang:

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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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 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 Part 803) for devices or postmarketing safety reporting (21 CFR Part 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 Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
