Abstract
Acoustic shielding system and method for protecting and shielding non-targeted regions or tissues that are not intended to be treated by ultrasonic procedures from acoustic energy using a shield. In some embodiments, the shield comprises multiple layers made of one or more materials with one or more acoustic impedances. In some embodiments a multilayered shield includes materials with relatively different acoustic impedance levels. In some embodiments, the shield includes active components such as energy diversion devices, heating, cooling, monitoring, and/or sensing. In some embodiments, the shield is configured to protect an eye, mouth, nose or ear while allowing the ultrasound to treat the surrounding tissue. One embodiment of an eye shield is configured to fit under at least one eyelid and over a portion of the eye.
