Intended Use
The Achilles ultrasonometer measures ultrasound variables of the os calcis to provide a clinical measure called Stiffness Index. The Stiffness Index indicates risk of osteoporotic fracture in postmenopausal women comparable to bone mineral density (BMD) as measured by X-ray absorptiometry at the spine or hip. Stiffness index results expressed as t-scores are used to assist the physicians in the diagnosis of osteoporosis in the same way as are t-scores or obtained by x-ray absorpiometry. Either the stiffness index t-score or x-ray absorpiometry t-score can be utilized by a physician, in conjunction with other clinical risk factors, to provide a comprehensive skeletal assessment. The stiffness index has a precision error in older women comparable to that of x-ray absorpiometry, which makes it suitable for monitoring bone changes.

No
The summary describes a device that measures ultrasound variables and calculates a "Stiffness Index" based on these measurements. There is no mention of AI, ML, or any related concepts like training sets, test sets, or complex algorithms that would typically indicate the use of AI/ML. The device appears to perform a direct calculation based on physical measurements.

No
The device is used for diagnosis and monitoring, specifically to indicate the risk of osteoporotic fracture and assist in the diagnosis of osteoporosis, rather than for treatment or therapy.

Yes
The device is used to "assist the physicians in the diagnosis of osteoporosis."

No

The device description explicitly states that the device "measures ultrasound variables," implying the use of hardware (an ultrasonometer) to acquire data, not just software processing of existing data.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices intended to be used in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or a congenital abnormality, or to determine the safety and compatibility with potential recipients, or to monitor therapeutic measures.
  • Device Function: The Achilles ultrasonometer measures ultrasound variables of the os calcis (heel bone) directly on the patient's body. It does not analyze specimens taken from the body.
  • Intended Use: The intended use is to provide a clinical measure (Stiffness Index) by in vivo measurement, not by analyzing in vitro samples.

Therefore, because the device operates by directly measuring a physical property within the patient's body using ultrasound, it falls outside the definition of an In Vitro Diagnostic device.

Summary of Performance Studies

A clinical study GE3120 was performed to determine the precision of the Achilles EXPII Bone sonometer and the correlation of the results for the Achilles EXPII and the Achilles Express. Stiffness Index results obtained from the Achilles EXPII was shown to be equivalent to those obtained by the Achilles Express in vivo. Linear regression of Stiffness Index values from the two devices demonstrated high correlation (R=0.97). Comparison of Stiffness values demonstrated no significant differences.

§ 892.1180 Bone sonometer.

(a)
Identification. A bone sonometer is a device that transmits ultrasound energy into the human body to measure acoustic properties of bone that indicate overall bone health and fracture risk. The primary components of the device are a voltage generator, a transmitting transducer, a receiving transducer, and hardware and software for reception and processing of the received ultrasonic signal.(b)
Classification. Class II (special controls). The special control for this device is FDA's “Guidance for Industry and FDA Staff; Class II Special Controls Guidance Document: Bone Sonometers.” See § 892.1(e) for the availability of this guidance document.

Dear Mr. Paulik:

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. 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.

If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895.
