Abstract:
1. An endoscopic device for generating acoustic waves, the endoscopic device comprising an endoscope having a sheath and defining a center axis, the sheath comprising: a first transducer configured to generate a first beam of acoustic energy that radiates outwards of the endoscope sheath at a predetermined first angle, a second transducer configured to generate a second beam of acoustic energy that radiates outwards of the endoscope sheath at a second angle that is different than the first angle such that the first beam and the second beam intersect at an intersection angle outside of the endoscope to define a focus spot, wherein the second transducer is linearly movable parallel to the center axis with respect to the first transducer to displace the second beam and therefore to displace the intersection of the first beam and the second beam at a second intersection angle to define a displaced focus spot, and wherein the second intersection angle is the same as the first intersection angle.
