No
The document describes standard ultrasound image processing and volume measurement techniques, with no mention of AI or ML.

No
The device is described as a "diagnostic ultrasound system" that "non-invasively determine[s] bladder volume" and "produce[s] on-screen images of anatomy," which indicates it is used for diagnosis rather than treatment.

Yes
The 'Device Description' explicitly states it is a "diagnostic ultrasound system," and its purpose is to "non-invasively determine bladder volume," which is a diagnostic function.

No

The device description explicitly states it is a "hand-held, diagnostic ultrasound system" and mentions projecting "ultrasound energy through the lower abdomen," indicating it includes hardware components for ultrasound generation and reception, not just software.

Based on the provided information, the Signos RT Bladder scanner is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Signos RT Bladder Scanner Function: The Signos RT Bladder scanner uses ultrasound energy to image the bladder within the patient's body and determine its volume. It does not analyze samples taken from the body.

The device is a diagnostic ultrasound system that performs a non-invasive measurement in vivo (within the living body). This falls under the category of medical devices, but specifically not IVDs.

§ 892.1560 Ultrasonic pulsed echo imaging system.

(a)
Identification. An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Dear Mr. Job:

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. 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.

9. Risk Analysis Method Used

Signostics Ltd applied ISO-14971 to the design and development of the SignosRT Bladder. The conclusion from the risk analysis was the device was safe for its intended use and does not pose any unacceptable risks.

10. Basis for Substantial Equivalence - Technological Characteristics

Signostics Ltd believes the SignosRT Bladder described in this Submission is substantially equivalent to the predicate devices as follows:

  • a. Portascan Bladder Scanner (K033906)
  • b. SignosRT Ultrasound System (K130659)

The SignosRT Bladder is substantially equivalent to the predicate devices listed above. All systems transmit ultrasonic energy into patients, then process received echoes to produce on-screen images of anatomy. All systems allow for B-mode imaging and measurements of volume of a bladder. The indication for use statement of the SignosRT Bladder is identical to the Portascan. The SignosRT Personal Ultrasound system (K130659) is a general ultrasound imaging device with an intended use statement covering a number of areas, including the abdomen which includes the bladder.

All systems enable an estimated bladder volume to be calculated from a single scan or from two scans for more accurate results. The algorithms used to calculate bladder volume are identical for the SignosRT Bladder and the predicate SpeqRT Personal Ultrasound System.

The SignosRT Bladder is identical in construction, materials, and controls to the SignosRT Personal Ultrasound (K130659), with the only difference being the indications for use statement and the software configuration. The patient contact materials are identical. The transducer and operating frequency (3.5MHz) are also identical. Both systems contain sector transducers with annular (circular) acoustic elements generating pie shaped images, have identical operating frequency, identical outer diameter of acoustic crystal, identical acoustic output, and both maintain MI and TI to be
