First Claim
Patent Images
1. A source of therapeutic acoustic waves comprising:
- at least two source elements each emitting therapeutic acoustic waves;
an instrument on which said at least two source elements are mounted adapted for introducing said at least two source elements into a body of a patient; and
means for mounting said at least two source elements on said instrument for permitting movement of said at least two source elements between an introduction position wherein said at least two source elements are relatively rotatably folded together in a first configuration and a working position wherein said at least two source elements are relatively rotatably unfolded in a second configuration, and vice versa, said first configuration having cross-sectional dimensions which are smaller than cross-sectional dimensions of said second configuration.

Abstract
A source of therapeutic acoustic waves for minimally invasive treatment of internal body regions with the therapeutic acoustic waves has a number of source parts which emit the acoustic waves. In order to be able to apply the source easily in the inside of the body in a simple way, source parts are arranged so as to be foldable in an introduction position giving the source a relatively small cross section as viewed in the introduction direction. After introduction into a patient the source parts are unfolded into a working position.

26. An apparatus for treating internal body regions with focused therapeutic acoustic waves, comprising:
-
a source of therapeutic acoustic waves adapted for introduction into a body of a patient having a plurality of source elements movable between an introduction position wherein said source elements are relatively rotatably folded together in a first configuration and a working position wherein said source elements are relatively rotatably unfolded in a second configuration, said first configuration having cross-sectional dimensions which are smaller than cross-sectional dimensions of said second configuration; means for driving said source for emitting therapeutic acoustic waves converging at a focus zone; means for driving said source for generating diagnostic ultrasound waves and for receiving corresponding ultrasound echoes from said patient for producing ultrasound images of said patient, and including means for mixing a mark into said ultrasound images identifying a current position of said focus zone; and means for adjusting a position of said focus zone for causing said focus zone to coincide with a region of said patient to be treated. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
