## Indications for Use

The Lyofoam® Extra "A" Sterile Adhesive Wound Dressing is intended for the treatment of moderately to heavily exuding wounds while the Modified Lyofoam® Wound Dressing would be used to treat lightly to moderately exuding, wounds. Lyofoam® Extra "A" provides a waterproof barrier for the wound which is moisture vapor permeable and helps to prevent bacterial contamination of the wound.

Intended Use, Comparison To Predicate Device:

The Lyofoam® Extra "A" Sterile Adhesive Wound Dressing is a combination of the Lyofoam® Extra product and the Modified Lyofoam® Dressing Product (Lyofoam® "A"). The main difference between them is that Lyofoam® Extra Foam Dressing is used in place of the regular Lyofoam® for the wound dressing pad segment of this product. The third layer of thin foam is extended beyond the wound pad and has a adhesive coating which is used to hold the product in place over the wound.

The inner absorbent layer of Lyofoam® Extra Wound Dressing Pad holds more excess wound fluid than the Modified Lyofoam® Wound Dressing Pad which is made from regular Lyofoam®. The Lyofoam® Extra "A" Sterile Adhesive Wound Dressing is intended for the treatment of moderately to heavily exuding wounds while the Modified Lyofoam® Wound Dressing would be used to treat lightly to moderately exuding, wounds. Lyofoam® Extra "A" provides a waterproof barrier for the wound which is moisture vapor permeable and helps to prevent bacterial contamination of the wound.
