1. A method of treating a wound with vibrational energy, comprising:
applying vibrational energy to a wound from an ultrasonic transducer, the ultrasonic transducer positioned within an absorbent wound dressing, the dressing comprising:
a wound contact layer, and
a delivery layer positioned above the wound contact layer, the delivery layer comprising a porous portion and a transmission portion, the transmission portion comprising a transmission material configured to transmit vibrational energy; and
controlling the ultrasonic transducer such that vibrational energy is delivered to the wound, the vibrational energy delivered at an acoustic power of about 3 mW/cm2 and a frequency of about 1.5 MHZ.
