Claim 17:
18. A wound therapy system for delivering reduced pressure and irrigation fluid to a wound site, the system comprising:
a wound enclosure configured to form a substantially sealed volume around the wound site;
a wound exudate collection canister;
a primary pressure source configured to deliver the reduced pressure to the substantially sealed volume and deliver exudate collected from the wound site to the wound exudate collection canister through a first lumen;
a secondary pressure source configured to deliver a secondary pressure to the substantially sealed volume through a second lumen;
a fluid source configured to deliver irrigation fluid to the substantially sealed volume through the second lumen; and
a valve system fluidly coupled to the secondary pressure source and the fluid source, the valve system operable to:
selectively couple the secondary pressure source to the second lumen for delivering the secondary pressure to the substantially sealed volume,
selectively couple the fluid source to the second lumen for delivering the irrigation fluid to the substantially sealed volume, and
selectively couple the secondary pressure source to the first lumen for bypassing the wound enclosure,

wherein the wound therapy system includes a first mode of operation wherein the secondary pressure source is coupled to the second lumen for delivering the secondary pressure to the substantially sealed volume and a second mode of operation wherein the fluid source is coupled to the second lumen and the secondary pressure source is coupled to the first lumen for delivering the irrigation fluid to the substantially sealed volume while secondary pressure delivered from the secondary pressure source bypasses the wound enclosure.
