The first shaft orderly penetrates through the sealed housing, the pivotal hole of the spiral-track plate, and the rotational shaft hole of the driving arm.

A method of a soft tissue treatment comprises placing an applicator adjacent to a surface of a body part, the applicator including at least one electrode, providing a fastening mechanism fixing the applicator in contact with the body part, providing a radiofrequency energy by the at least one electrode causing a heating of the soft tissue, providing an electric current to the soft tissue by the at least one electrode causing a muscle contraction, and controlling heating of the soft tissue by the radiofrequency energy and parameters of the electric current provided by the at least one electrode via a control unit, wherein an energy flux density of the radiofrequency energy is in a range of 0.01 mW.Math.mm.sup.−2 to 10 W.Math.mm.sup.−2 and a frequency of the radiofrequency energy is in a range of 0.1 MHz to 25 GHz, and wherein the body part comprises a face or a chin.

The present discussion relates to the delivery of ultrasonic therapy energy to a target region in conjunction with a clear path determination that may assess one or more of: (1) presence of non-soft tissue regions within the therapy beam path (e.g., bone or bone-like structures, gas-filled cavities, and so forth), (2) partial “lift-off” of the probe head; or (3) sufficiency of acoustic coupling. Upon determination or confirmation of at least a partial clear path with respect to some or all of these factors, the therapy beam may be delivered to the target region.

An ablation system for treating atrial fibrillation in a patient comprises an elongate shaft having proximal and distal ends, a lumen therebetween and a housing adjacent the distal end of the elongate shaft. An energy source is coupled to the housing and is adapted to deliver energy to a target tissue so as to create a zone of ablation in the target tissue that blocks abnormal electrical activity thereby reducing or eliminating the atrial fibrillation in the patient. A sensor is adjacent the energy source and adapted to detect relative position of the energy source to the target tissue or characteristics of the target tissue. The system also has a reflecting element operably coupled with the energy source and adapted to redirect energy emitted from the energy source in a desired direction or pattern.

Provided is an ultrasonic generator with an adjustable ultrasonic focusing depth. The ultrasonic generator with an adjustable ultrasonic focusing depth includes a cartridge housing in which an ultrasound generation portion generating ultrasonic waves is provided, a hand piece in which the cartridge housing is detachably mounted, the hand piece having a first actuator thereinside, and a main shaft to which the ultrasound generation portion is coupled so as to reciprocate in a horizontal direction, parallel to the bottom of the cartridge housing and a vertical direction, perpendicular to the bottom of the cartridge housing. One end of the main shaft is coupled to one end of the first actuator of the hand piece, and an other end of the main shaft is located inside the cartridge housing. The hand piece includes an adjustment portion adjusting an ultrasonic focusing depth of the ultrasound generation portion.

Systems, devices, and methods involve ablation of tissue to treat rhinitis and/or other nasal conditions. Implementations allow treatment of tissue in the confined space of the nasal cavity. Additionally, implementations allow targeted treatment tissue to be ablated, while protecting other non-treatment tissue from unintentional collateral effects that might be produced by the ablation. According to an example implementation, an approach for treating a nasal condition includes advancing a probe into a nasal cavity, the probe including a shaft and a cryotherapy element coupled to the shaft. The approach also includes cryogenically cooling a target treatment site with the cryotherapy element to treat at least one nasal nerve. Additionally, the approach includes transmitting a focused ultrasound beam to a target heating site to increase a temperature tissue at the target heating site.

An ultrasound probe for treating body tissues, which includes a focused ultrasound emitter arranged inside a main body provided with a porn that can be gripped, and a means for connection to a remote unit for the power supply and control of the probe. The particularity of the present invention resides in that it includes a means for adjusting the penetration depth of a beam of focused ultrasound, emitted by the emitter, in a tissue of a patient.

Embodiments of a dermatological cosmetic treatment and/or imaging system and method can include use of transducer to create a linear thermal treatment zone at a focal depth to form a band shaped treatment area. The system can include one or more ultrasound transducers, a cylindrical transduction element, an imaging element, a hand wand, a removable transducer module, a control module, and/or graphical user interface. In some embodiments, a coated transducer may be used to provide more consistent treatment in cosmetic procedures, including brow lifts, fat reduction, sweat reduction, and treatment of the décolletage. Skin tightening, lifting and amelioration of wrinkles and stretch marks are provided. Treatment may include heating of tissue for a duration to deactivate a percentage of cells in the treatment region.

The present invention relates to a low-intensity focused ultrasound therapeutic device. According to one aspect of the present invention, provided is a low-intensity focused ultrasound therapeutic device which employs a single element ultrasound transducer having a focal region, a focal distance and output intensity that can be provide safer treatment for the deep brain of a patient.

A system and method for controlling the delivery of ultrasound energy to a subject is provided. In particular, such a system and method are capable of safely disrupting the blood-brain barrier. Ultrasound energy is delivered to produce cavitation of an ultrasound contrast agent at a selected pressure value. An acoustic signal is acquired following cavitation, from which a signal spectrum is produced. The signal spectrum is analyzed for the presence of harmonics, such as subharmonics or ultraharmonics. When subharmonics or ultraharmonics are present, the pressure value is decreased for subsequent sonications. If a previous sonication resulted in no subharmonics or ultraharmonics being generated, then the pressure value may be increased. In this manner, the blood-brain barrier can be advantageously disrupted while mitigating potentially injurious effects of the sonication.
