Abstract
A wound treatment system includes a distribution manifold, a reduced pressure source, a fluid delivery source, and an ultrasonic energy transducer. Reduced pressure and fluid delivery may be applied to the wound through the distribution manifold. The ultrasonic energy transducer is configured to deliver ultrasonic energy to the wound to debride the wound. The ultrasonic energy transducer may be either a piezoelectric transducer or a surface acoustic wave device. The ultrasonic energy transducer may be placed adjacent to the distribution manifold to deliver ultrasonic energy directly to the wound or may be coupled to an acoustically-conducting membrane positioned between the distribution manifold and the wound.
