Abstract
An ultrasound therapy probe includes a therapy transducer movably mounted on a probe body, a partially deformable flexible casing disposed around the therapy transducer, and a guard ring that limits deformations of the flexible casing when the transducer moves with respect to the probe body. The therapy transducer can be moved between a therapy position and a retracted position, and the guard ring provides an end-of-travel stop against which the therapy transducer bears when in a therapy position. A first opening is provided for injecting liquid into the flexible casing, and a second opening is provided for withdrawing liquid from the flexible casing. The second opening is located on the guard ring so that bubbles are withdrawn from the flexible casing as soon as they form.
