In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.

A catheter system for treating a treatment site within or adjacent to a vessel wall includes a light source, a balloon, a light guide, and an optical analyzer assembly. The light source generates light energy. The balloon is positionable substantially adjacent to the vascular lesion. The balloon has a balloon wall that defines a balloon interior that receives a balloon fluid. The light guide receives light energy from the light source at a guide proximal end and guides the light energy toward a guide distal end and into the balloon interior. The optical analyzer assembly is configured to optically analyze light energy emitted from the guide proximal end of the light guide.

A method for treating a treatment site within or adjacent to a vessel wall or a heart valve, includes the steps of (i) generating light energy with a light source; (ii) positioning a balloon substantially adjacent to the treatment site, the balloon having a balloon wall that defines a balloon interior that receives a balloon fluid; (iii) receiving the light energy from the light source with a light guide at a guide proximal end; (iv) guiding the light energy with the light guide in a first direction from the guide proximal end toward a guide distal end that is positioned within the balloon interior; and (v) optically analyzing with an optical analyzer assembly light energy from the light guide, wherein the light energy that is analyzed moves in a second direction that is opposite the first direction.

Exemplary embodiments of system, methods and computer-accessible medium can be provided for performing feedback-controlled electromagnetic radiation (EMR)-based treatment. Some exemplary embodiments include an image acquisition system configured to detect information regarding at least one portion of a tissue, and an EMR source configured to generate an EMR beam. A controller can be provided that can be configured to (i) recognize one or more targets within the portion(s) of the tissue based upon the feedback data, (ii) locate one or more coordinates within the portion(s) associated with the target(s), and (iii) control the optical arrangement to direct the EMR beam to impact the coordinate(s).

A device for light-based skin treatment is provided. The device comprises a light source for providing an incident light beam for treating a skin, optical elements for focusing the incident light beam in a focal point inside the skin, and a skin interface element for, during use of the device, providing optical coupling of the incident light beam from the device into the skin. The skin interface element comprises a transparent exit window for allowing the incident light beam to leave the device, on top of the exit window, a transparent mixture of a polar substance and an apolar substance, and on top of the transparent mixture, a transparent foil, the transparent foil being more hydrophobic than the exit window.

A medical laser apparatus according to an embodiment of the present invention comprises: a laser oscillation unit for oscillating a laser; a beam width adjustment unit for adjusting the beam width of the laser oscillated from the laser oscillation unit; and a concentration unit for concentrating the laser of which the beam width has expanded by means of the beam width adjustment unit.

Provided herein is a multifunctional aesthetic system including a housing, an electromagnetic array situated in the housing and having a plurality of electromagnetic radiation (EMR) sources, each EMR source configured to generate an EMR beam having a wavelength different than that of an EMR beam generated by another of the EMR sources, a controller in electronic communication with the array to operate two or more of the EMR sources to direct the EMR beam to a treatment area, and a sensor in electronic communication with the controller for providing feedback to the controller based on defined parameters to allow the controller to adjust at least one operating condition of the multifunctional system in response to the feedback.

A co/counter propagating acousto-optic modulator is provided that creates a low-intensity focused ultrasound (FUS) wave on a laser beam in a medium such as water without any auxiliary mediators or special software/hardware. The main optical effect of the FUS is the controllable focusing of the laser beam through modification of the refractive index of the medium in a time-stable and dynamic fashion. The laser beam and the FUS wave are coaxially mixed and propagated through each other. The FUS pressure field highly amplifies the power density, highly amplifies the intensity, sharpens the diameter, and reduces the full width at half maximum (FWHM) of the laser beam. The FUS pressure field keeps the laser beam's lensing power positive, with small fluctuations, as long as the ultrasound wave is coaxially propagated with the laser beam.

An end effector assembly for an optical surgical instrument includes a jaw member and a plurality of optical elements positioned within a cavity of the jaw member. The jaw member has a tissue contacting surface. The jaw member has a proximal portion that is configured to secure a fiber optic cable thereto such that a distal end of the fiber optical cable extends into the cavity. The plurality of optical elements are arranged in a staircase-like manner that rises towards the tissue contacting surface as the plurality of optical elements extends distally within the cavity. The plurality of optical elements is configured to direct a beam of light exiting the fiber optic cable towards the tissue contacting surface.
