Affinity® details and resources
Affinity, as a protective wound covering, supports an optimal environment for healing in a variety of wound types
As the only fresh amniotic membrane wound covering on the market, Affinity is the gold standard choice—closest to a native, unprocessed amniotic membrane.1-3
Affinity is an allograft intended for use in the management of acute and chronic wounds as well as appropriate surgical applications. Affinity may be applied as a wound covering to a variety of partial- and full-thickness acute and chronic wounds, such as:
- Trauma wounds
- Dehisced wounds
- Pressure ulcers
- Venous leg ulcers (VLUs)
- Diabetic foot ulcers (DFUs)
- Wounds with exposed bone and tendon
Affinity application steps4
Preparation of the wound bed:
Ensure that the wound is free of infection. Sharp debridement should be performed and extended to healthy, viable bleeding tissue. Hemostasis should be achieved, and heavy exudate controlled.
- Using aseptic technique, remove the inner tray from the outer tray
- Peel back the foil lid from the inner tray, remove Affinity, and place the product on the inner side of the foil lid
- Identify which side is facing up by touching the surface with a sterile cotton swab
- If the stromal or sticky side is up, then turn Affinity over, so that the stromal side is facing down on the foil lid. If the epithelial or non-sticky side is facing up, then you do not need to turn the product over
- Rinse with a sterile irrigant prior to application
- Slide Affinity off the foil lid and onto the wound so that the stromal side is in contact with the wound bed
- Two forceps can be used to help with orientation
- Trim Affinity as needed so that it is slightly larger than the wound bed
Dressings and re-application schedule†:
- Anchor Affinity using preferred fixation method, then cover Affinity with a primary nonadherent dressing to remain in place for up to 1 week
- Apply a secondary dressing that controls drainage and provides a moist wound environment
- Reapply Affinity weekly and continue sharp debridement as necessary
- Offload or compress appropriately based on wound type
