A method for conducting intrabody surgery by means of a surgical device having a cutting arrangement actuated by a driveshaft and rotationally supported by the guide wire. A receiving cannel extends through the cutting arrangement and movably receives the guidewire. A plurality of sensors is provided within the cutting arrangement to emit signals capable of changing parameters depending on the composition of the occlusion, so as to allow the control unit to generate signals controlling operation of the cutting arrangement. The method includes the steps of detecting parameters within the intrabody area by the sensors to controlling operation of the cutting arrangement with the power and control unit.

Methods and systems for treating skin, such as stretch marks through deep tissue tightening with ultrasound are provided. An exemplary method and system comprise a therapeutic ultrasound system configured for providing ultrasound treatment to a shallow tissue region, such as a region comprising an epidermis, a dermis or a deep dermis. In accordance with various exemplary embodiments, a therapeutic ultrasound system can be configured to achieve depth with a conformal selective deposition of ultrasound energy without damaging an intervening tissue. In addition, a therapeutic ultrasound can also be configured in combination with ultrasound imaging or imaging/monitoring capabilities, either separately configured with imaging, therapy and monitoring systems or any level of integration thereof.

A method and device for skin or deeper organ treatment uses an applicator that includes a transducer for producing beams of pressure waves and a coupler for coupling the pressure waves to the skin or deeper organ. The pressure waves in the skin and deeper propagate in directions generally extending at small angles relative to the skin surface

Embodiments of the present disclosure are directed to methods of inducing therapeutic adipose tissue inflammation using high frequency pressure waves (e.g. high frequency shockwaves) wherein the inflammation results in a reduction in the volume of subcutaneous adipose tissue. Embodiments include applying electrohydraulic generated shockwaves at a rate of between 10 Hz and 100 Hz to reduce the appearance of cellulite or the volume of subcutaneous fat in a treatment area.

The present disclosure provides an extracorporeal focused ultrasound treatment device for a pelvic disease. The treatment device includes an ultrasonic transducer and a treatment couch. Sound emitting surface of the ultrasonic transducer is a spherical surface having a first notch, a second notch and a third notch, the first notch and the second notch are respectively positioned at two intersections of the spherical surface and a diameter perpendicular to the main great circle, and the third notch connects the first notch with the second notch; a cross-section of the sound emitting surface parallel to the main great circle is in a shape of an arc; and an ultrasonic wave generated by the sound generation unit is focused at a center of the sphere corresponding to the sound emitting surface. The treatment couch is configured for a human body to lie in a lithotomy position.

Disclosed herein are example embodiments of devices, systems, and methods for mechanical fractionation of biological tissue using magnetic resonance imaging (MRI) feedback control. The examples may involve displaying an image representing first MRI data corresponding to biological tissue, and receiving input identifying one or more target regions of the biological tissue to be mechanically fractionated via exposure to first ultrasound waves. The examples may further involve applying the first ultrasound waves and, contemporaneous to or after applying the first ultrasound waves, acquiring second MRI data corresponding to the biological tissue. The examples may also involve determining, based on the second MRI data, one or more second parameters for applying second ultrasound waves to the biological tissue, and applying the second ultrasound waves to the biological tissue according to the one or more second parameters.

The present invention relates to a therapeutic ultrasonic wave generating device. The present invention includes: a rotating motor; an ultrasonic wave generating unit being provided with a transducer generating ultrasonic waves; and a focus rotation movement unit moving the focus of the ultrasonic waves generated by the ultrasonic wave generating unit in a circle on the same plane by receiving a transmission of rotational force of the rotating motor. The present invention enables: the focus of ultrasonic waves to be moved in the circle having a constant radius at a uniform depth under the skin; and energy to be applied uniformly and evenly within the movement radius, thereby enabling enhancement of therapeutic performance.

Methods of treating the skin and in particular removing pigment from a tattoo are provided. In preferred embodiments, a piezoelectric transducer is placed at a plurality of locations above the skin and focused acoustic waves at 7 MHz or more are transmitted into the skin. The focal point of the focused acoustic waves is between 0.1 mm and 5 mm below the surface of the skin. The design of the piezoelectric transducer along with the frequency of operation are carefully chosen to create points of treatment with a desired size and shape. The correct amount of energy is supplied to the points of treatment to produce a lesion of a desired size and shape. The lesions are spaced and located to effect the treatment of the skin.

A controller changes a position and/or orientation of a treatment head by controlling an operation of a robot arm according to an external input. A probe driver changes a projection amount of a diagnostic probe with respect to an irradiator. Further, the controller performs synchronous control to synchronize the probe driver and the robot arm with each other so that the relative position between the irradiator and the distal end of the diagnostic probe changes while holding the distal end position of the diagnostic probe.
