Device Story

Butterfly iQ is a handheld diagnostic ultrasound system; consists of a single transducer probe connected to a commercial off-the-shelf (COTS) mobile device. Operates by capturing ultrasound signals; transforms inputs into B-mode, M-mode, Color Doppler, and Power Doppler images. Used by trained healthcare professionals in clinical environments. Operator controls system via touchscreen interface on the mobile device to view and measure imagery. Output assists clinicians in diagnostic assessment of anatomical structures and fluids; facilitates procedural guidance. Benefits include portable, point-of-care diagnostic imaging capability.

Clinical Evidence

Bench testing only. Performance verified against IEC 60601-1 (safety), IEC 60601-1-2 (EMC), IEC 60601-2-37 (ultrasound safety), ISO 10993 (biocompatibility), and NEMA UD-2 (acoustic output). No clinical data presented.

Technological Characteristics

Handheld diagnostic ultrasound system; single 2D phased array transducer probe. Connectivity via COTS mobile device. Energy source: battery-powered (120-minute scan time). Software-based image processing. Complies with IEC 60601-1, IEC 60601-1-2, IEC 60601-2-37, ISO 10993, and NEMA UD-2 standards.

Indications for Use

Indicated for trained healthcare professionals to perform diagnostic ultrasound imaging and measurement of anatomical structures and fluids in adult and pediatric patients (including fetal). Applications: peripheral vessel, procedural guidance, small organs, cardiac, abdominal, urology, fetal/obstetric, gynecological, musculoskeletal, and ophthalmic.

Regulatory Classification

Identification

An ultrasonic pulsed doppler imaging system is a device that combines the features of continuous wave doppler-effect technology with pulsed-echo effect technology and is intended to determine stationary body tissue characteristics, such as depth or location of tissue interfaces or dynamic tissue characteristics such as velocity of blood or tissue motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

Dear Prithul Bom:

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 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

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

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).
