A method of cutting a bone (2) comprises the steps of: preparing the bone (2) in order to be accessible to an osteotomic instrument; predefining an osteotomic geometry on the bone (2); and applying the osteotomic instrument to the bone (2) thereby cutting the bone (2) along the osteotomic geometry and generating a cut surface (21) to the bone (2). The method further comprises delivering a laser beam to the cut surface (21) of the bone (2) such that the cut surface (21) of the bone (2) is ablated. The method according to the invention allows to improve healing of a bone at its cut surface after being cut by the osteotomic instrument.

A method of treatment of skin tissue with two laser devices of unequal wavelengths comprising the steps of: (1) activating the two laser devices simultaneously to produce two laser beams of unequal wavelength; (2) directing the two laser beams into a handpiece having a distal tip to direct the laser beams onto the skin tissue; (3) directing the two laser beams within the handpiece to an adjustable beam deflector; and, (4) the adjustable beam deflector directing the two laser beams onto the skin tissue to produce a pattern of laser spots simultaneously but separated from one another.

In one aspect, methods of treating a wound are described herein. A method described herein, in some embodiments, comprises treating a wound, such as a chronic wound, by performing a full field laser ablation in a wound bed of the wound and subsequently performing a fractional laser ablation in the wound bed. Additionally, in some cases, the fractional laser ablation step is carried out at substantially the same time as, or immediately following, the full field laser ablation step. In addition, in some instances, a method described herein further comprises performing debridement in the wound bed prior to performing the full field laser ablation in the wound bed.

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 vascular lesion within or adjacent to a vessel wall includes an energy source, a plurality of energy guides and a system controller. The energy source generates energy. The plurality of energy guides receive energy from the energy source. The system controller controls the energy source so that the energy is sequentially directed to each of the plurality of energy guides in an advancing wavefront. The system controller controls a firing rate of the energy source to each of the plurality of energy guides. The system controller can control a firing sequence to the plurality of energy guides so that the advancing wavefront is generated toward the vascular lesion from near the balloon proximal end and from near the balloon distal end. The system controller can control the energy source so that light energy from the energy source is alternatively directed to at least two of the plurality of energy guides at a different firing energy level from one another. The energy level can be based on pulse width, wavelength and/or amplitude of the energy pulse(s).
