The main difference between them is that Lyofoam® Extra is used in place of the regular Lyofoam® for the wound dressing segment of this product. Both have the same activated carbon layer for odor absorption. The inner absorbent layer of Lyofoam® Extra "C" Odor Absorbing Wound Dressing holds more excess wound fluid than Lyofoam® "C". This would allow the Lyofoam® Extra "C" to be left on the wound without changing for a longer period of time. The Lyofoam® Extra "C" Odor Absorbing dressing is intended for the treatment of moderately to heavily exuding wounds, while Lyofoam® "C" would be used to treat lightly to moderately exuding wounds. Performance data for the Lyofoam® Extra dressing segment of this product can be found in the Lyofoam® Extra 510(K) file K952565. 75 Kings Highway Cutoff • Fairfield, CT 06430 • Phone: (203) 332-7330 • Fax: (203) 576-0022 {2} K961323 Page 14 # Asme United Corporation ## Safety: Safety test data can be found in both the Lyofoam® Extra 510(K) file K952565 and Lyofoam® "C" Odor Absorbing Wound Dressing 510(K) file; K864084.
