Ferris PolyMem WIC Silver Cavity Wound Filler — Fills Dead Space, Silver Antimicrobial, Separates into Strips

A multifunctional cavity wound filler that cleanses, fills, absorbs, and moistens — while killing 99.9% of bacteria and adapting to any wound shape. Ferris PolyMem WIC Silver Cavity Wound Filler is a 3" x 3" hydrophilic polymeric membrane pad specifically engineered for shallow cavity wounds, undermined wounds, and broad-base wounds with dead space where a flat dressing cannot establish full wound contact. The pre-slit, perforated design allows the pad to be separated into three individual 1" wide strips — so the clinician can size the filler precisely to the wound without waste, cutting, or loss of structural integrity. Once placed in the cavity, the PolyMem Silver matrix activates on contact with wound fluid — expanding approximately one-third to fill dead space, absorbing up to 10 times its weight in exudate, cleansing by drawing contaminants into the polymer structure, and moistening dry wound surfaces as needed. Small-particle silver distributed throughout the matrix releases silver ions continuously as the dressing absorbs, creating a sustained antimicrobial environment that kills 99.9% of tested organisms directly at the wound base where infection risk is highest.

✔ Pre-Slit Perforated Design — Separates Into Three 1" Strips for Precise Fit, No Cutting    ✔ Expands to Fill Dead Space — Eliminates Voids Where Bacteria Proliferate    ✔ Silver Kills 99.9% of Bacteria — Continuous Release at the Wound Base    ✔ Four-Action Technology — Cleanses, Fills, Absorbs & Moistens Simultaneously    ✔ Will Not Fragment — One-Piece Removal Every Time

Product Details

Indicated For — Wound Types

• Pressure injuries — Stage 3 and Stage 4 with cavity or dead space
• Shallow cavity wounds requiring a pad-format filler rather than a rope
• Undermined wounds — broad-base undermining where full wound contact is needed across the undermined area
• Vascular ulcers with cavity components — venous, arterial, and mixed etiology
• Diabetic foot ulcers with cavity or depth
• Dehisced surgical wounds — post-operative cavities healing by secondary intention
• Acute and chronic wounds with moderate to heavy exudate and cavity depth
• Infected or at-risk cavity wounds requiring silver antimicrobial activity at the wound base
• Palliative wounds requiring exudate management, odor control, and wound pain relief
• Sloughy wounds requiring debridement in combination with cavity management

Note: Use for cavity wounds with a broader opening — for deep narrow tunneling or sinus tract wounds use PolyMem WIC Silver Rope (item 1814) instead. A secondary dressing is required over the cavity filler. Do not pack the wound too tightly — allow room for the approximately one-third expansion on absorption. For infected wounds follow local clinical protocols.

How It Works — Four-Action Silver Technology for Cavity Wounds

Cavity wounds present two distinct wound management problems that standard flat dressings cannot address: dead space and depth. A flat foam or alginate dressing placed over a cavity wound does not contact the wound base — leaving the cavity void unfilled, allowing exudate to pool at depth, and creating an environment where bacteria can proliferate without contact with the dressing's antimicrobial agents. PolyMem WIC Silver solves both problems simultaneously. The pad is placed directly into the cavity without backing, allowing it to conform and expand as it absorbs — filling the dead space, eliminating the void, and ensuring the silver-impregnated matrix is in direct contact with the entire wound base. As the matrix absorbs wound fluid, it simultaneously draws contaminants and necrotic debris into the polymer structure, wicks excess exudate away from the wound surface, donates moisture to any dry wound areas, and releases silver ions throughout the absorption process — creating and maintaining an antimicrobial environment at the wound base where topically applied antiseptics often cannot reach.

• Cleanses — polymer matrix draws contaminants, bacteria, and debris into the dressing structure
• Fills — expands approximately one-third within the cavity to eliminate dead space
• Absorbs — holds up to 10 times its own weight in exudate, managing moderate to heavy wound drainage
• Moistens — donates fluid to dry wound surfaces when dressing carries more moisture than the wound bed
• Silver ions released continuously during absorption — kills 99.9% of tested organisms at the wound base
• Autolytic debridement — helps loosen and slough necrotic tissue as the dressing hydrates the wound bed
• Reduces wound pain and odor — PolyMem technology clinically noted to relieve wound-associated pain
• Will not fragment or adhere to wound bed — painless one-piece removal at every dressing change
• Pre-slit strips allow precise sizing — use one, two, or all three strips as the wound requires
• Can be cut to any shape without compromising structural integrity or silver distribution
• Made in USA — Ferris Manufacturing, FSA eligible

The Pre-Slit Design — Precision Fit for Any Cavity

One of the most common challenges with flat cavity wound fillers is fitting them to wounds that are smaller than the pad — cutting standard foam or alginate pads to fit creates loose edges and potential for fragmentation. PolyMem WIC Silver 1333 eliminates this problem with a built-in pre-slit perforated design. The 3" x 3" pad has two parallel perforations running the full length of the pad, dividing it into three equal 1" x 3" strips. The strips separate cleanly along the perforated lines without scissors or cutting tools — leaving clean, defined edges on each strip. The clinician can use the full pad for larger cavities, two strips for medium wounds, or a single strip for compact cavity wounds — with no waste, no cutting tools required, and no loose fragment risk from the separation.

• Pre-slit perforations divide 3" x 3" pad into three 1" x 3" strips — no scissors needed
• Strips separate cleanly with defined edges — no fragment risk from the separation process
• Use 1, 2, or all 3 strips to match the wound dimension precisely
• Each strip maintains full silver distribution and PolyMem matrix properties after separation
• Can be further cut to shape after strip separation for highly irregular wound geometries
• Unused strips can be stored in the original packaging and used for subsequent dressing changes

WIC Silver Cavity vs. WIC Silver Rope — Choosing the Right Format

Application Tips: Separate the pad into the appropriate number of strips using the perforated lines. Place loosely into the wound cavity — do not pack tightly, allow room for approximately one-third expansion. Sterile saline or water can be added to pre-moisten the dressing if the wound is dry. Cover with an appropriate secondary dressing.
