Intended Use
Cytal® Wound Matrix is intended for the management of wounds including: partial and full thickness wounds, pressure ulcers, venous ulcers, diabetic ulcers, chronic vascular ulcers, tunnel/undermined wounds (donor sites/grafts, post-Mohs surgery, podiatric, wound dehiscence), trauma wounds (abrasions, lacerations, second-degree burns, and skin tears), and draining wounds. The device is intended for one-time use. Cytal® Burn Matrix is intended for the management of wounds including: second-degree burns, partial and full thickness wounds, pressure ulcers, venous ulcers, diabetic ulcers, tunnel/undermined woundermined wounds, surgical wounds (donor sites/grafts, post-Mohs surgery, post-laser surgery, podiatric, wound dehiscence), trauma wounds (abrasions, lacerations, and skin tears), and draining wounds. The device is intended for one-time use.
Device Description
The UBM devices are composed of a resorbable porcine-derived extracellular matrix (ECM) scaffolds, containing epithelial basement membrane, known as urinary bladder matrix (UBM). Cytal devices are supplied in single or multi-layer sheet configurations (1 to 6 layers) in sizes up to 10 cm x 15 cm (1-, 2, and 6-Layer, K152721) or 16 x 35 cm (3-Layer, K192725). Cytal sheets are provided with fenestrations in both lyophilized (1- and 2-Layer) and vacuum pressed (3- and 6-Layer) configurations. The devices are packaged in double peel-open pouches. The devices are terminally sterilized using electron beam irradiation and are intended for one-time use. UBM devices are pre-hydrated with sterile saline and applied to the wound. The devices can be cut to size and/or used in conjunction with other extracellular matrix derived scaffolds indicated for wound management, such as MicroMatrix® UBM Particulate. The devices are sloughed from the skin during the normal wound healing process or are incorporated (remodeled) into the wound bed via enzymatic degradation, cellular infiltration, capillary growth, and/or integration by the surrounding host tissue.
More Information

Not Found

No
The summary describes a biological matrix device for wound management and does not mention any software, algorithms, or AI/ML capabilities.

Yes
The device is intended for the management of various types of wounds, indicating it is used for treatment and healing purposes.

No

The device description and intended use indicate that Cytal® Wound Matrix and Cytal® Burn Matrix are resorbable extracellular matrix scaffolds used for the management and healing of various types of wounds, rather than for diagnosing conditions or diseases.

No

The device description explicitly states it is composed of a resorbable porcine-derived extracellular matrix (ECM) scaffolds, 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 the wound to aid in healing.
  • Device Description: The description details a physical matrix made from porcine tissue that is applied to the wound and either sloughed off or incorporated into the tissue. This is a therapeutic device, not a diagnostic one.
  • Lack of Diagnostic Function: There is no mention of the device being used to test samples (like blood, urine, or tissue) in vitro to diagnose a condition, monitor a disease, or screen for a health issue.
  • Performance Studies: The performance studies focus on the physical properties and stability of the matrix (dimensional analysis, hydration uptake, tensile strength, etc.), which are relevant to a wound management device, not an IVD.

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 applied to the body to treat a condition (wounds).
