What makes PolyMem different?

PolyMem provides unrivaled benefits for clinicians and patients. Unlike foam dressings, whose primary purpose is to absorb, PolyMem dressings are designed to facilitate healing, relieve pain and reduce inflammation in a unique way. Each PolyMem dressing includes a hydrophilic polyurethane matrix with a mild, tissue-friendly wound cleanser, a soothing moisturizer, a superabsorbent, and a semi-permeable film backing. This unique formulation of ingredients works synergistically to provide unrivaled benefits for clinicians and patients.

More Healing…

PolyMem dressings debride and constantly cleanse the wound bed, while also managing exudate. The wound bed will not be disturbed during dressing changes because PolyMem dressings are non-adherent. PolyMem also stimulates healing by drawing fluid (including nutrition and growth factors) to the wound. PolyMem dressings are specifically designed to focus inflammation to where it is needed — in the wound. This helps reduce swelling and pain which helps reduce the risk of infection which support the healing process.

…Less Pain

PolyMem dressings contain a moisturizer that helps keep the dressing from adhering to the wound bed and provides comfort at the wound site. The wound cleanser in the dressing reduces the need for manual (often painful) wound bed cleansing at dressing change, while also facilitating for effective autolytic debridement, which offers an excellent alternative to more painful debridement options. PolyMem dressings often provide relief of persistent wound pain, procedural wound pain relief and reduced pain with activity due to the demonstrated ability of the dressings to focus the inflammation response.


The PolyMem family of dressings can be used as primary dressings, secondary dressings or a combination of both to support the entire healing continuum. PolyMem dressing configurations are available for use on wounds with dry, slight, moderate, or heavy drainage/exudate.

Applying Science to the Art of Wound Care and Pain Treatment

The PolyMem formulation was first patented in 1988 by Robert W. Sessions, a former director of biomedical research at Chicago’s Rush-Presbyterian St. Luke’s Medical Center. Ferris Mfg. Corp. and founder, Sessions, have received numerous awards and recognitions for excellence in medical product design and contributions to the medical profession.

Sessions is responsible for numerous inventions, including: one of the first implantable cardiac pacemakers; disposable electrocardiogram electrodes; a disposable bone marrow aspiration needle; a suture-less cannula for open heart surgery; the Hunter-Sessions Vena Cava Occluder (an implant to prevent blood clots in the lungs); and the PolyMem® wound dressings, BabySmooth Diaper Rash Pads, RhinoPak® Nasal Surgery Dressings, as well as Pain Soothing Back Support.
