More Information

No
The document describes a collagen wound dressing and does not mention any software, algorithms, or data processing that would indicate the use of AI or ML.

Yes
The device is intended for the management of wounds and supports wound healing, which falls under therapeutic use.

No

Explanation: The device is described as a wound dressing intended for the management and healing of wounds, not for diagnosing conditions. Its function is therapeutic/supportive (maintaining a moist environment for healing), not diagnostic.

No

The device description clearly states it is a "native bovine collagen wound dressing," which is a physical material, not software.

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

Here's why:

  • Intended Use: The intended use clearly states that the device is for the "management of wounds." This involves applying the device directly to a wound on a patient's body to aid in healing.
  • Device Description: The description details a "wound dressing" that is applied to a wound.
  • Lack of IVD Characteristics: There is no mention of the device being used to test samples (like blood, urine, or tissue) in vitro (outside of the body) to diagnose a condition, monitor a treatment, or screen for diseases.

IVD devices are used to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. This device is a therapeutic wound dressing applied directly to the body.

LUOFUCON® Collagen Particles has the similar indications for use, and very similar technological characteristics to the predicate device(K171645). Both devices are 100% collagen and are designed as powder form, Tyvek packaging, single-use, sterile product. Their main production process includes drying, grinding, and irradiation sterilization. The subject and predicate devices employ the same mode of action in that both devices contain an absorbent nature that maintains a moist wound environment to support wound healing.

LUOFUCON® Collagen Particles is compliant with FDA guidance-Medical Devices Containing Materials Derived from Animal Sources (Except for In Vitro Diagnostic Devices).

7. Non-Clinical Data/Information

7.4 Animal-Derived Materials Safety

Based on utilization of animal derived materials in LUOFUCON® Collagen Particles, the requirements of safety is compliant with FDA quidance document-Medical Devices Containing Materials Derived from Animal Sources (Except for In Vitro Diagnostic Devices) and ISO 22442 standards.

The subject device has the same collagen raw materials and animal source as the reference device (K213598), and the information related to the safety of animal-derived materials had been submitted and approved by the FDA in the previous K213598 submission.

8. Conclusions

LUOFUCON® Collagen Particles has the similar indications for use, material composition, mode of action and very similar technological characteristic as predicate device, with differences in sterilization method, in-vitro degradation time, and packaging size.

Furthermore, the subject and reference device share a common collagen raw material. The subject device has the same processing steps except for an additional grinding process to the reference device, it is ground into powder on the basis of the reference device (collagen sheet). The safety of the reference device has been established and cleared by FDA, any potential safety risks associated with the change in shape of the reference device from sheet to powder form have been addressed through comparison and analysis.

Based on the information provided as summarized above, the minor differences between devices raise no new issues of safety or effectiveness. It can be concluded that the subject device is substantially equivalent to the predicate device(K171645) with regard to indications for use, technological characteristics, performance tests, animal-sourced material, and biocompatibility.
