摘要：
A tissue treatment apparatus and method are provided for treating tissue by theapplication of the time-varying sub-atmospheric pressure. The apparatus includesa cover adapted to cover a wound and adapted to maintain sub-atmospheric pressurethe site of the wound. The apparatus further includes a source of suction configuredto generate a time-varying sub-atmospheric pressure having a periodic waveformcomprising a gradual change in pressure. The suction source cooperates withthe cover to supply the time-varying sub-atmospheric pressure under the coverto the wound. The time-varying sub-atmospheric pressure may vary between a firstpressure value below the inherent tissue tension of the wound tissue and a secondpressure value above the inherent tissue tension of the wound tissue.
