1. A probe for applying sonic energy within the body of a subject comprising:
- (a) a probe body having a proximal end and a distal end adapted for insertion into the body of the subject;
(b) a spatially-distributed sonic transducer disposed adjacent said distal end of said probe body, said sonic transducer including a continuous transducer sheet, said sonic transducer being operative to apply therapeutic ultrasonic energy so as to heat tissues within the body of a subject to a temperature sufficient to create a therapeutic effect; and
(c) means for moving one portion of said transducer relative to another portion of said distributed transducer while said distal end of said probe is disposed within the body of the subject.

Abstract
An apparatus and method for applying sonic energy within the body of the living subject. A probe for applying sonic energy within the body of a subject includes a probe body having a proximal and a distal end adapted for insertion into the body of a subject, a spatially-distributed sonic transducer disposed adjacent to the distal end of the probe body and a device for moving one portion of the spatially-distributed transducer relative to another portion of the transducer while the distal end of the probe is disposed within the body of the subject.

12. A probe for applying sonic energy within the body of a subject comprising:
-
(a) a probe body having a proximal end and a distal end adapted for insertion into the body of the subject, said distal end of probe body being deformable;
(b) a spatially-distributed sonic transducer mounted to said distal end of said probe body and mounted to said probe body so that deformation of said distal end of said probe body will move one portion of said sonic transducer relative to another portion of said sonic transducer; and
(c) means for deforming said distal end of said probe body while said distal end of said probe is disposed within the body of the subject. - View Dependent Claims (13, 14)

16. A probe for applying sonic energy within the body of a subject comprising:
-
(a) a probe body having a proximal end and a distal end adapted for insertion into the body of the subject;
(b) a spatially-distributed sonic transducer disposed adjacent said distal end of said probe body;
(c) a plurality of supports movable relative to the probe body, said distributed transducer including a plurality of transducer elements mounted to said supports; and
(d) means for moving one or more of said supports relative to said probe body so as to move one of said transducer elements relative to another one of said transducer elements. - View Dependent Claims (17, 18, 19)
