Dynamic, reduced-pressure treatment systems and methods

A method of manufacturing a reduced-pressure treatment system for treating a tissue site, comprising:

• providing a reduced-pressure delivery member for delivering reduced pressure to the tissue site, the reduced-pressure delivery member comprising a first lumen and a second lumen;
• segregating the first lumen from the second lumen with a liquid-impermeable-and-gas-permeable member, the liquid-impermeable-and-gas-permeable member adapted to substantially preclude liquid from entering the second lumen to provide a liquid flow in the first lumen and a gas flow in the second lumen;
• and
• coupling a wave generator in fluid communication with the first lumen, the wave generator for imparting a wave to the liquid flow in the first lumen.

A method for treating a tissue site, comprising:

• providing reduced pressure to the tissue site;
• substantially segregating liquid and gas carried by the reduced pressure from the tissue site into a separate liquid flow and a separate gas flow;
• and
• coupling a wave generator in fluid communication with the separate liquid flow for imparting a wave to the liquid flow.

A reduced-pressure delivery member, comprising:

• a first lumen adapted to transmit a liquid and having a first interior space;
• a second lumen adapted to transmit a gas and having a second interior space;
• and
• a liquid-impermeable-and-gas-permeable member coupled to the second lumen in at least a portion of the second interior space, the liquid-impermeable-and-gas-permeable member adapted to substantially segregate the liquid into a separate liquid flow and the gas into a separate gas flow.

A reduced-pressure delivery member, comprising:

• a first lumen adapted to transmit a gas and having a first interior space;
• a second lumen adapted to transmit a liquid and having a second interior space;
• the first lumen comprising a fluid impermeable material;
• and
• the second lumen comprising a liquid-impermeable-and-gas-permeable member and disposed within the first interior space, the liquid-impermeable-and-gas-permeable member adapted to substantially segregate the liquid into a separate liquid flow and the gas into a separate gas flow.
