No
The device description and intended use are solely focused on the physical properties and function of a sterile ultrasound coupling gel. There is no mention of any software, algorithms, or data processing capabilities that would indicate the use of AI or ML.
No
The device is described as an ultrasound coupling agent used for medical imaging and diagnostic procedures, not for treatment or therapy.
No
The device is described as an ultrasound coupling agent, a gel that couples sound waves between the patient and medical imaging electronic transducers. Its purpose is to facilitate diagnostic imaging (e.g., ultrasounds), but it does not independently perform a diagnostic function.
No
The device description clearly states that the device is a "phase changing hydrogel ultrasound coupling agent" and is contained in a "single use 5cc capped syringe." This indicates a physical product, not software.
No, this device 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. They are used to provide information for diagnosis, monitoring, or screening.
- Ultrast Gel's Function: Ultrast Gel is a coupling agent used in ultrasound procedures. Its purpose is to facilitate the transmission of sound waves between the ultrasound transducer and the patient's body. It does not analyze or test any biological samples from the patient.
- Intended Use: The intended use clearly states it's a "scanning gel" and a "coupling gel" for "in vivo" (within the living body) procedures. It's used to improve the quality of the ultrasound image, not to perform a diagnostic test on a sample.
Therefore, based on the provided information, Ultrast Gel is a medical device used to aid in diagnostic imaging, but it is not an in vitro diagnostic device.

Device Description
The Ultrast Gel device, manufactured for Ultrast, Inc. is a phase changing hydrogel ultrasound coupling agent comprised of hydroxy-propylcellulose, sodium chloride, sodium citrate, and water. HCl may be added to adjust pH if necessary. The gel is viscous at room temperature, but subsequently liquefies as its temperature rises and reaches body temperature. In addition to general lubricating/coupling properties, the gel may be instilled in the uterine cavity through a standard intrauterine insemination (IUI) catheter to provide excellent ultrasonographic visualizations, after which point it liquifies and passes out of the uterine cavity.
The gel is contained in a single use 5cc capped syringe enclosed in a peel pouch to maintain sterility.

6.1. Comparison of Technological Characteristics and Substantial Equivalence Conclusion
The proposed device has identical an intended use and identical indications for use compared to the predicate, as such there are no issues of substantial equivalence based on the proposed use. When examining technological characteristics, the proposed device is very similar to the predicate. Its major difference is the phase-changing characteristics that allow for easier removal. This phase change takes place after the ultrasound procedure and therefore leads to no significant questions of safety and effectiveness compared to the predicate. That is, the feature is described in the instructions for use and is supported by performance testing to demonstrate it works as intended. The minor differences in formulation are supported by the acoustic testing and biocompatibility testing. Other performance testing substantial equivalence includes sterilization validation and shelf-life/stability evaluation.
Based on the detailed comparison between the predicate devices and the subject device, the Ultrast Gel can be found substantially equivalent to the predicate device.
7. PERFORAMNCE DATA
Biocompatibility Testing
Ultrast Gel is an Implant Device contacting Tissue/Bone for a Limited Contact Duration. As such, biocompatibility testing was carried out according to the requirements in the following standards:
