Intact Fish Skin for Wound Healing

Managing challenging chronic and acute wounds

Our intact fish skin grafts for hospital outpatient departments, wound clinics, and physician offices have helped thousands of healthcare providers with some of their most challenging cases.  

Kerecis Shield® Products  

Shield® is intact fish skin indicated for the management of chronic and acute wounds such as diabetic foot ulcer wounds, pressure ulcers, vascular ulcers, post-Moh’s surgical wounds, and draining wounds commonly treated in physician’s private offices.

The grafts contain fat, protein, elastin, glycans and other natural skin elements, and are fenestrated to allow adequate wound drainage for appropriate wound moisture at the wound bed. Shield products are integrated with a silicone contact layer to protect the wound and for added workflow efficiency.

Shield products are classified as medical devices, and consist of intact fish skin that has been processed using Kerecis’ proprietary EnviroIntact™ method. The products are not subject to the May 31, 2021, FDA 351 regulation.

Benefits of using Kerecis Shield®

Known Challenges in Wound Care

Optimum application of biologic solutions is dependent on the right environment, including:

Timely Graft Removal. Biologics are highly active in the wound bed, so providers need to prevent the graft from getting stuck in a covering dressing, or being accidentally removed by someone on the care team.

Similarly, providers need to avoid the risk of exudate getting stuck under the graft or dressing: Diabetic Foot Ulcers (DFUs) and other lower extremity wounds may have increased exudate initially when biologic grafts are used, so ensuring the exudate doesn’t get trapped under the graft or dressing is essential for best outcomes.

Time is everything for healthcare providers. Gathering the ideal contact layer or covering dressing is not just time consuming, it can be infeasible in certain situations.


“Shield helps to protect the wound environment while speeding up the preparation and application process…”

Shield use in Wound Management

The Solution: Shield is specially designed to help address these challenges.

A protective “shield” directly on the fish skin graft helps ensure the fish skin does not get stuck in covering dressings, and allow for optimal drapability so it conforms to the wound. The contact layer on Shield Adhesive helps keep the graft in place for the initial placement, then separate from the graft and allow for removal of the silicone without pulling away the graft.

Exudate management is the cornerstone of all good wound care. A silicone without proper exudate control could trap fluids and risk pooling of exudate, infections or hematomas forming. To help reduce this risk, Shield products have specially-designed fenestration lines in the fish skin graft, and extra large pores in the silicone. This allows for maximum fish skin contact with the wound, and maximum drainage while still providing protective coverage.

All included in a single product, Shield helps to protect the wound environment while speeding up the preparation and application process, helping to ensure patients get the best possible outcome from their fish skin graft application.
