Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 108 words
An article of manufacture comprising: (a) a movable focusing member and piezoelectric element means for emitting therapeutic treatment waves mounted in operative relation to said member, said member having a concave focusing surface shaped so that therapeutic treatment waves emitted from said element means when activated converge at a focal zone; (b) a hole through said member; (c) a support and auxiliary sectorial sweep scanning transducer means for generating a sectorial sweep mounted on said support, said scanning transducer means sweeping independently of movement of said member; and (d) said support passing through said hole so that said scanning transducer means is between said zone and said surface.
Claim 2
Dependent Claim 108 words
An article of manufacture comprising: (a) a movable focusing member and piezoelectric element means for emitting therapeutic treatment waves mounted in operative relation to said member, said member having a concave focusing surface shaped so that therapeutic treatment waves emitted from said element means when activated converge at a focal zone; (b) a hole through said member; (c) a support and auxiliary sectorial sweep scanning transducer means for generating a sectorial sweep mounted on said support, said scanning transducer means sweeping independently of movement of said member; and (d) said support passing through said hole so that said scanning transducer means is between said zone and said surface.
Claim 3
Dependent Claim 19 words
An article as set forth in claim 1 wherein said hole passes through said member along an axis thereof.
Claim 4
Dependent Claim 28 words
An article as set forth in claim 1 wherein said support is generally cylindrically shaped and passes through said member into a volume generated by said concave shape.
Claim 5
Dependent Claim 21 words

Claim 6
Dependent Claim 18 words
An article as set forth in claim 1 wherein said hole is axially symmetrical with said focusing member.
Claim 7
Dependent Claim 18 words
An article as set forth in claim 1 wherein said concave focusing surface is an active focusing surface.
Claim 8
Dependent Claim 18 words
An article as set forth in claim 1 wherein said element means is fixed to said focusing member.
Claim 9
Dependent Claim 20 words
An article of manufacture as set forth in claim 1 wherein said element means is mounted against said focusing surface.
Claim 10
Dependent Claim 26 words
An article of manufacture as set forth in claim 1 wherein said scanning transducer means is mounted generally along a central axis of said focusing surface.
Claim 11
Dependent Claim 20 words
An article of manufacture as set forth in claim 1 wherein said element means comprises a plurality of piezoelectric elements.
Claim 12
Dependent Claim 27 words
An article of manufacture as set forth in claim 1 wherein said scanning transducer means is located at least partially in a path of said treatment waves.
Claim 13
Dependent Claim 109 words
An article of manufacture comprising: (a) piezoelectric elements; (b) a movable focusing member having a concave focusing surface, said elements being engaged with said focusing member in operative relation thereto and juxtaposed to form a mosaic, when activated said elements emitting treatment waves directed by said member to a focal area; (c) a hole through said member; (d) sectorial sweep scanning transducer support means, for positioning a scanning transducer mounted in said hole; and (e) a sectorial sweep scanning transducer mounted to said support means so that said transducer is between said surface and said area; and means generating a scanning transducer sweep independent of movement of said member.
Claim 14
Dependent Claim 109 words
An article of manufacture comprising: (a) piezoelectric elements; (b) a movable focusing member having a concave focusing surface, said elements being engaged with said focusing member in operative relation thereto and juxtaposed to form a mosaic, when activated said elements emitting treatment waves directed by said member to a focal area; (c) a hole through said member; (d) sectorial sweep scanning transducer support means, for positioning a scanning transducer mounted in said hole; and (e) a sectorial sweep scanning transducer mounted to said support means so that said transducer is between said surface and said area; and means generating a scanning transducer sweep independent of movement of said member.
Claim 15
Dependent Claim 20 words
An article as set forth in claim 12 wherein said hole passes through said focusing member along an axis thereof.
Claim 16
Dependent Claim 18 words
An article as set forth in claim 12 wherein said hole is axially symmetrical with said focusing surface.
Claim 17
Dependent Claim 17 words

Claim 18
Dependent Claim 27 words
An article as set forth in claim 12 wherein said support means is generally cylindrically shaped and is mounted in the concave part of said focusing surface.
Claim 19
Dependent Claim 33 words
An article as set forth in claim 12 wherein said support means comprises a sleeve, wherein said transducer is mounted on said sleeve, and wherein said sleeve is fixed to said focusing member.
Claim 20
Dependent Claim 18 words
An article as set forth in claim 12 wherein said piezoelectric elements are mechanically isolated from each other.
Claim 21
Dependent Claim 21 words
An article as set forth in claim 12 wherein said scanning transducer projects within the volume generated by said focusing surface.
Claim 22
Dependent Claim 21 words
An article according to claim 12 in which the piezoelectric elements are mounted in an annular array in a circular pattern.
Claim 23
Dependent Claim 17 words
An article according to claim 12 in which the piezoelectric elements are integral with said focusing surface.
