Intended Use
PELNAC™ Bilayer Wound Matrix is indicated for the management of wounds including: - · partial and full-thickness wounds, - · pressure ulcers, - · venous ulcers, - · diabetic ulcers, - · chronic vascular ulcers, - · surgical wounds (donor sites/grafts, post-Moh's surgery, post-laser 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.
Device Description
PELNAC™ Bilayer Wound Matrix is a collagen-based wound matrix that consists of two layers: a porcine collagen sponge layer and a silicone film layer and is offered in two versions: 1. Meshed Type (i.e., fenestrated) and 2. Non-Meshed Type (i.e., non-fenestrated). The collagen sponge layer should be applied to the wound surface. Both versions of the device also contain a synthetic gauze material to add strength to the silicone film layer. When applied to full-thickness skin defects, PELNAC™ Bilayer Wound Matrix provides a scaffold for cellular invasion and capillary growth. PELNAC™ Bilayer Wound Matrix is offered in sheet form of various sizes and is provided terminally sterilized by ethylene oxide, is for single patient use, and can only be applied to a patient by a qualified doctor in a professional setting for the management of full-thickness skin defects as described in its product labeling.
More Information

No
The device description and performance studies focus on the material properties and clinical outcomes of a collagen-based wound matrix, with no mention of AI or ML technology.

Yes
The device is described as a 'Bilayer Wound Matrix' indicated for the management of various wounds, providing a scaffold for cellular invasion and capillary growth, which are therapeutic actions.

No
The device, PELNAC™ Bilayer Wound Matrix, is described as a collagen-based wound matrix intended for the management of various types of wounds, providing a scaffold for cellular invasion and capillary growth. Its function is to treat and manage wounds, not to diagnose medical conditions or identify the nature of a disease.

No

The device description clearly states it is a collagen-based wound matrix consisting of physical layers (collagen sponge, silicone film, synthetic gauze) and is provided in sheet form, indicating it is a physical medical device, not software.

Based on the provided information, 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.
  • Device Description and Intended Use: The description of PELNAC™ Bilayer Wound Matrix clearly states it is a collagen-based wound matrix applied directly to the wound surface for the management of various types of wounds. It acts as a scaffold for cellular invasion and capillary growth. This is a therapeutic device applied in vivo (on the body), not a diagnostic test performed in vitro (outside the body).
  • Lack of Diagnostic Activity: There is no mention of this device analyzing biological samples or providing diagnostic information about a patient's condition. Its function is to aid in wound healing.

Therefore, PELNAC™ Bilayer Wound Matrix is a medical device used for wound management, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

  • Human Repeat Insult Patch Test (HRIPT): Conducted on 56 subjects. PELNAC Bilayer Wound Matrix was applied 9 times during the induction phase, with evaluations at each visit. After a 2-3 week rest, subjects were challenged with the device at the same area, and evaluated at 24, 48, 72 & 96 hours for irritation and Type IV allergic response.
    • Key results: None of the 56 subjects developed irritation or sensitization. No adverse events related to the product, demonstrating it is neither an irritant nor a sensitizer.
  • Clinical Use Cohort Study: PELNAC Bilayer Wound Matrix was used on a cohort of 18 subjects who sustained finger degloving injuries. Subjects ranged in age from 19 to 66 years, with a mean age of 42 years. The device was placed within 2 days of injury and remained for 21 days. Patients were followed weekly until day 21, and then at 3, 6, 9, and 12 months. Assessments included biopsy samples and histological analysis at the 12-month follow-up.
    • Key results: No reports of expanding erythema, edema, pain, vesicles, or other immune response that would signal removal of the dressing.

Dear Stuart Goldman:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmp/pmn.cfm identifies combination product submissions. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

10. Summary of Clinical Data

To address the subject product immunogenicity, a Human Repeat Insult Patch Test (HRIPT) was conducted on 56 subjects. PELNAC Bilayer Wound Matrix was placed on the subjects 9 (nine) times during the induction phase and the area was evaluated at each visit prior to the next patch placement. After 2-3 weeks rest period the subjects were challenged by placing the device at the same area and evaluated at 24, 48, 72 & 96 hours for irritation and Type IV allergic response. The results demonstrated that none of the 56 subjects developed irritation or sensitization. There were no adverse events related to the product demonstrating that PELNAC Bilayer Wound Matrix is neither an irritant nor a sensitizer.

12

In lieu of the prick test to demonstrate that the subject device does not elicit immunogenic reaction (antibodymediated) and does not cause any local inflammatory tissue responses, PELNAC Bilayer Wound Matrix was used on a cohort of 18 subjects who sustained finger degloving injuries. The subjects ranged in age from 19 to 66 years, mean age 42 years. They received the subject device within 2 days of their injury, and it remained in place for 21 days. The patients remained in the hospital for at least 24 hours after the surgery in which the subject device was placed and then were evaluated weekly until day 21. There were no reports of expanding erythema, edema, pain, vesicles, or other immune response that would signal removal of the dressing. All subjects were followed at 3, 6, 9, and 12 months. Assessments were evaluated at the 12 month follow up including biopsy samples and histological analysis.

11. Statement of Substantial Equivalence

PELNAC™ Bilayer Wound Matrix has the same intended use and indications for use as AVAGEN Wound Dressing. Any minor differences in the technological features of the subject device when compared to the predicate device have been successfully evaluated through safety and other verification and validation activities. PELNAC™ Bilayer Wound Matrix, as designed and manufactured by GUNZE LIMITED has been determined to be substantially equivalent to the predicate device, AVAGEN Wound Dressing.
