No clinical data included. Substantial equivalence supported by bench testing, including compliance with IEC 80601-2-30:2018, ISO 81060-1:2007, and biocompatibility testing (ISO 10993-5:2009, ISO 10993-10:2010).

Technological Characteristics

Polyester cuff with internal bladder; hook and loop closure. Pressure range 0-300 mmHg. Single-tube configuration. Biocompatibility per ISO 10993-5 and ISO 10993-10. Non-sterile, reusable. Mechanical device; no energy source or software.

Indications for Use

Indicated for adult patients requiring non-invasive blood pressure monitoring when used with compatible measurement systems.

Regulatory Classification

Identification

A blood pressure cuff is a device that has an inflatable bladder in an inelastic sleeve (cuff) with a mechanism for inflating and deflating the bladder. The cuff is used in conjunction with another device to determine a subject's blood pressure.

Dear Alex 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.
