The device description and performance studies focus on the material properties and equivalence to a predicate device, with no mention of AI or ML.
Yes
The device is indicated for the "symptomatic management of rectal mucositis," which aims to treat or alleviate a medical condition.
No
Explanation: The device description and intended use clearly state that PuraStat is a hydrogel for the "symptomatic management" of rectal mucositis by providing a "protective barrier." It is used to treat a condition, not to diagnose it.
No
The device is a gel delivered via a syringe and catheter, which are physical components, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "symptomatic management of rectal mucositis," which is a treatment or management function, not a diagnostic one.
- Device Description: The device is a gel applied to the rectal mucosa to form a protective barrier. This is a physical barrier and not a test performed on a sample taken from the body to diagnose a condition.
- No mention of diagnostic testing: There is no mention of analyzing samples (like blood, urine, tissue, etc.) or providing diagnostic information.
- Anatomical Site: The application is directly to the rectal mucosa, not for testing a sample.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

PuraStat is intended to be used for the symptomatic management of rectal mucositis, such as radiation proctitis that may be caused by chemotherapy or radiotherapy.
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS 6.
The subject device is identical to the PuraStat-RM predicate (K213552) except for the final sterilization, which is replaced by gamma radiation sterilization. The final product specifications are unchanged.
PuraStat comprises of a synthetic repeating 16-amino acid (RADA-16) oligopeptide in sterile water for injection. In the presence of physiological pH (blood or tissue), the peptides assemble into a scaffold structure that results in the formation of a protective coating over the rectal mucosa.. The solution is filtered and filled into 5-ml syringes made of cyclo-olefin polymers with a highdensity polyethylene plunger and a butyl rubber head cap and gasket. Each syringe is filled with either 1, 3, or 5 ml of gel. The device is terminally sterilized, and the resorbable gel is delivered to the intended application site(s) via a commercially available adapter connected to a commercially available catheter. The device is delivered endoscopically via a catheter to the patient.
7. PERFORMANCE DATA
The subject device is identical to the predicate device. The intended use of the subject device is identical to the intended use of the predicate device K213552. The indications for use of the subject device are identical to the predicate's indications for use.
The subject device is identical to the predicate device and has the same intended use, and an equivalence demonstration was performed following the final sterilization change. The bench testing and biocompatibility testing provided in this submission assess the equivalence demonstration.
Overall, the difference in technological characteristics (Final sterilization) of the subject and the predicate device 3-D Matrix Inc. - PuraStat-RM do not raise any new questions of safety and effectiveness.
