Ferris Polymem WIC Silver Rope Wound Filler a unique dressing that moistens the wound, absorbs exudate, fills in cavities, and maintains a clean healing environment for tunneling and cavity wounds. The hydrophilic polymeric membrane matrix wound filler is reinforced with medical-grade mesh to increase its resilience during application and removal. It can hold up to six times its weight in exudate. As it absorbs exudate, the dressing expands to fill the wound and deny harmful substances from entering. This action helps maintain a clean environment. Also, the absorption process releases silver ions, protecting the bed from microbial growth. These silver ions help reduce infections, allowing the wound to heal properly. An independent study suggests that Polymem Silver kills over 99% of the tested organisms. These silver dressings are intended for deep tunneling and cavity wounds, such as acute wounds and ulcers. It requires a secondary dressing as it is non-adherent. We offer the Eclypse Secondary Dressing CR3818 | 3-9/10 x 3-9/10 Inch by Advancis for this purpose.
