Abstract
Device and methods for the treatment of wounds using ultrasound energy are disclosed. The portable wound treatment device may deliver ultrasound energy to a wound through direct contact with the ultrasound tip and/or through a liquid coupling medium. Several ultrasound tips specially designed to concentrate and focus ultrasound energy onto a wound are also disclosed. The ultrasound tip may also possess an abrasive peripheral boundary to aid in debriding the wound and/or removing necrotic tissue. The disclosed invention may have multiple beneficial effects in treating a wound such as sterilizing a wound, reducing external bleeding, and/or providing pain relief.
