PolyMem WIC Wound Cavity Fillers

Deep wounds, tunneling, and undermined areas can't heal from the surface down — they need a filler that reaches into the cavity, manages exudate, and keeps the wound bed active. That's the role of PolyMem WIC wound cavity fillers from Ferris. These non-adhesive polymeric membrane dressings are placed loosely into the wound space, where they cleanse, fill, absorb, and moisten in a single step, then are removed and replaced at each dressing change.

The Ferris PolyMem WIC Nonimpregnated Wound Cavity Filler (5733) is a sterile 3 x 3 inch pad built on a hydrophilic membrane matrix. It draws exudate away from the wound while releasing moisture where the bed is dry, helping maintain the balanced environment full-thickness wounds need. Because it isn't adherent, it lifts out without disrupting new tissue — a meaningful difference for patients who dread painful removals.

For wounds where bioburden or infection risk is a concern, the PolyMem Silver WIC Cavity Filler (1333) adds ionic silver to the same 3 x 3 inch polymeric matrix. The silver provides sustained antimicrobial action within the cavity while the dressing continues its cleansing and absorbing work, making it a practical choice for pressure injuries, surgical wounds left to heal by secondary intention, and other cavity wounds showing signs of contamination.

A common question with cavity fillers is how much to use: the material should fill the space loosely, never packed tightly, and should be sized so it can be retrieved as one piece. Both versions require a secondary cover dressing to hold them in place and complete the seal.
