    Abstract: A surgical tissue therapy device includes a sealant layer and a collection chamber. The sealant layer functions so as to create a sealed enclosure, or space between it and the surface of a patient, by forming an airtight seal around a surgical area of skin trauma. The closed incision tissue therapy device also comprises a collection chamber, which may comprise an elongate tubular chamber with a plurality of longitudinally spaced openings. The collection chamber may be configured to be in fluid communication with the sealant layer and the area of skin trauma and functions as to distribute the negative pressure applied to a surgically closed area of skin trauma. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of air molecules under the sealant layer. The collection material may comprise a material and/or a configuration that permits length changes based upon the length of the corresponding surgical wound or incision.
