Therapeutic ultrasound apparatus and method

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.

1 . A therapeutic ultrasound device for use during a medical procedure to cauterize tissue, the therapeutic ultrasound device comprising:
 an inner tube having a proximal end and a distal end,
 wherein the distal end of the inner tube comprises a first engagement portion configured to receive and secure a first moveable fastener; 
   an outer tube having a proximal end and a distal end,
 wherein the distal end of the outer tube comprises a second engagement portion configured to receive and secure a second moveable fastener, and 
 wherein the outer tube is disposed about the inner tube such that the second engagement portion is aligned with the first engagement portion; 
   a tissue clamping assembly having a width less than about 15 millimeters and configured to apply a clamping force at a target site,
 wherein the tissue clamping assembly includes at least one transducer configured to provide therapeutic ultrasound, 
 wherein the tissue clamping assembly comprises a first jaw and a second jaw, and 
 wherein a distal end of the tissue clamping assembly is configured to engage with the first engagement portion of the inner tube and the second engagement portion of the outer tube; and 
   a housing assembly secured to the proximal end of the inner tube and the proximal end of the outer tube, wherein the housing assembly comprises a handle configured to actuate the inner tube relative to the outer tube and close the tissue clamping assembly.
