| 20080234641 | System and method for managing reduced pressure at a tissue site - The illustrative embodiments described herein are directed to an apparatus and method for managing reduced pressure at a tissue site. The apparatus includes a reduced pressure source that generates reduced pressure. The reduced pressure is delivered to the tissue site via a delivery tube.
