Abstract
An apparatus for treatment of body tissue includes a treatment apparatus configured to be inserted into a patient. The treatment apparatus has a distal portion, a distal end, a proximal portion and an axis. An ultrasound transducer is positioned at the distal portion of the treatment apparatus. The ultrasound transducer includes a distal ultrasound energy delivery surface and a proximal ultrasound energy delivery surface. An ultrasound energy attenuator member is positioned adjacent to the proximal ultrasound energy delivery surface and is made of a material to at least partially attenuate ultrasound energy from the proximal ultrasound energy delivery surface.
