Therapeutic ultrasound applicator for the urogenital region

Claim 2

A therapeutic ultrasound applicator for the urogenital region comprising: a housing containing an acoustic propagation medium and having an exit surface adapted for non-invasive placement against a patient; and ultrasound generator means, having a working axis, for generating focused ultrasound waves converging to a working region and which always have a cross section completely occupied by said ultrasound waves in a plane proceeding at a right angle relative to said working axis circumscribed by an envelope having a first principal axis intersecting said working axis and a second principal axis intersecting said first principal axis at substantially a right angle, said first principal axis having a length exceeding a length of said second principal axis, and said ultrasound waves exiting through said exit surface.

Claim 3

A therapeutic ultrasound applicator as claimed in claim 1 wherein said first principal axis has a length exceeding said second principal axis by at least a factor 1.5.

Claim 4

A therapeutic ultrasound applicator as claimed in claim 1 wherein said length of said first principal axis exceeds said length of said second principal axis at least by a factor 2.

Claim 5

A therapeutic ultrasound applicator as claimed in claim 1 wherein said ultrasound generator means comprises two substantially circular shaped focused ultrasound resonators disposed in V-shaped orientation, each ultrasound resonator having a focus and the foci of said ultrasound resonators being disposed in said working region.

Claim 6

A therapeutic ultrasound applicator as claimed in claim 1 wherein said exit surface comprises a resilient coupling membrane.

Claim 7

A therapeutic ultrasound applicator as claimed in claim 1 further comprising: a support member disposed in said housing and having a support surface; a carrier member, to which said ultrasound generator means is attached, disposed in said housing and having a carrier surface mating with said support surface, said support surface and said carrier surface having a cooperating shape for permitting spherical adjustment of the position of said working region.

Claim 8

A therapeutic ultrasound applicator as claimed in claim 6 further comprising means for mounting said support member in said housing for permitting axial displacement of said support member relative to said housing.

Claim 9

A therapeutic ultrasound applicator as claimed in claim 1 further comprising an ultrasound locating means for generating an image of said working region, said ultrasound locating means including an ultrasound locating transducer contained in an ultrasound applicator disposed in said ultrasound generator means.

Claim 10

A therapeutic ultrasound applicator as claimed in claim 8 wherein said ultrasound locating transducer is disposed on said working axis.

Claim 11

A therapeutic ultrasound applicator as claimed in claim 8 wherein said ultrasound locating transducer has a longitudinal axis, and further comprising means for mounting said ultrasound locating transducer for permitting displacement of said ultrasound locating transducer along said longitudinal axis.

Claim 12

A therapeutic ultrasound applicator as claimed in claim 8 wherein said ultrasound locating transducer has a longitudinal axis and further comprising means for mounting said ultrasound locating transducer for permitting rotation around said longitudinal axis.

Claim 13

A therapeutic ultrasound applicator for the human male urogenital region comprising: a housing containing an acoustic propagation medium and having an exit surface adapted for placement against a human male subject; and ultrasound generator means contained in said housing for emitting ultrasound waves through said exit surface propagating along a working axis and focused onto a working region, said ultrasound waves having a non-circular cross section completely occupied by said ultrasound waves in a plane perpendicular to said working axis and adapted to always cause said ultrasound waves to pass unimpeded between the pelvic bones of said subject when said housing is placed with said exit surface between the scrotum and rectum of said subject.

Claim 14

A therapeutic ultrasound applicator for the human male urogenital region comprising: a housing containing an acoustic propagation medium and having an exit surface adapted for placement against a human male subject; and ultrasound generator means contained in said housing for emitting ultrasound waves through said exit surface propagating along a working axis and focused onto a working region, said ultrasound waves having a non-circular cross section completely occupied by said ultrasound waves in a plane perpendicular to said working axis and adapted to always cause said ultrasound waves to pass unimpeded between the pelvic bones of said subject when said housing is placed with said exit surface between the scrotum and rectum of said subject.

Claim 15

A therapeutic ultrasound applicator for the urogenital region comprising: a housing containing an acoustic propagation medium and having an exit surface adapted for non-invasive placement against a patient; and ultrasound generator means for generator focused acoustic waves converging to a working region, said ultrasound generator means having an emission surface from which said ultrasound waves emanate and a working axis along which said ultrasound waves propagate, said emission surface having a shape such that said ultrasound waves have a cross section in a plane proceeding at a right angle relative to said working axis completely occupied by said ultrasound waves and circumscribed by an envelope having a first principal axis intersecting said working axis and a second principal axis intersecting said first principal axis at substantially a right angle, said first principal axis having a length exceeding a length of said second principal axis, and said ultrasound waves exiting through said exit surface.

Claim 16

A therapeutic ultrasound applicator for the urogenital region comprising: a housing containing an acoustic propagation medium and having an exit surface adapted for non-invasive placement against a patient; and ultrasound generator means for generator focused acoustic waves converging to a working region, said ultrasound generator means having an emission surface from which said ultrasound waves emanate and a working axis along which said ultrasound waves propagate, said emission surface having a shape such that said ultrasound waves have a cross section in a plane proceeding at a right angle relative to said working axis completely occupied by said ultrasound waves and circumscribed by an envelope having a first principal axis intersecting said working axis and a second principal axis intersecting said first principal axis at substantially a right angle, said first principal axis having a length exceeding a length of said second principal axis, and said ultrasound waves exiting through said exit surface.
