Abstract: Various devices related to a therapeutic ultrasound device for use during a medical procedure to cauterize tissue are disclosed. The therapeutic ultrasound device can include an inner tube assembly and an outer tube assembly. The device can further include a tissue engagement assembly that is secured to the distal end of the inner tube and the distal end of the outer tube. The tissue engagement assembly includes a plurality of transducers configured to provide therapeutic ultrasound. The device can include a housing assembly that is secured to the proximal end of the inner tube and the proximal end of the outer tube. The housing assembly can include a handle configured to actuate the inner tube relative to the outer tube to engage and disengage the tissue engagement assembly.

Abstract: Various devices related to a therapeutic ultrasound device for use during a medical procedure to cauterize tissue are disclosed. The high intensity focused ultrasound device can include a transducer for producing high intensity focused ultrasound. The transducer includes a shell configured to receive an acoustic stack. The acoustic stack includes a piezoelectric layer, a matching layer, and a plurality of electrodes. The transducer includes an air-filled pocket formed between the inner surface of the shell and the piezoelectric layer of the acoustic stack, wherein the air-filled pocket is configured to ensure high efficiency of the transducer.

Abstract: Various devices related to a therapeutic ultrasound device for use during a medical procedure to cauterize tissue are disclosed. The device includes an apparatus for tissue engagement. The apparatus includes a first jaw and a second jaw that each includes a body portion and an ear located adjacent to the body portion. The body portion is configured to receive an acoustic stack and the ear includes a slot configured to receive a first pin. The first and second jaws include an opening located between the body portion and the ear. The opening is configured to receive a second pin such that the first jaw and the second jaw are configured to rotate about the second pin.
