Claim 11:
12. A method for delivering reduced pressure and irrigation fluid to a wound site, the method comprising:
providing a wound therapy system, the wound therapy system including:
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 independently of the irrigation fluid and selectively couple the fluid source to the second lumen for delivering the irrigation fluid to the substantially sealed volume independently of the secondary pressure;

delivering secondary pressure from the secondary pressure source to the wound enclosure through a second lumen while the valve system prevents delivery of the irrigation fluid to the substantially sealed volume through the second lumen during a first mode of operation;
delivering irrigation fluid from the fluid source to the wound enclosure through the second lumen while the valve system prevents delivery of the secondary pressure to the substantially sealed volume through the second lumen during a second mode of operation;
preventing the delivery of both the secondary pressure and the irrigation fluid to the wound enclosure during a third mode of operation; and
continuously delivering reduced pressure from the primary pressure source to the wound enclosure through a first lumen during each of the first mode of operation, the second mode of operation, and the third mode of operation.
