A laser device for treating a target region of biological tissue comprises: a sheath; at least two optical fibers in the sheath, each configured to guide a laser beam to the target region, distal ends of at least two of the optical fibers configured so that each emits a laser beam in a different direction; a system of laser sources configured to generate at least two laser beams, the two laser beams having different or identical wavelengths with adjustable power; and a laser-beam control unit configured to control the system of laser sources so as to select the wavelength, the power, the duration of the deposition of laser energy, and the moment of emission of each of the laser beams in the direction of the target region so as to dynamically generate and adjust a 3D thermal distribution having a geometric shape matching a geometric shape of the target region.

Aspects of this disclosure pertain to a device with an elongated body having a distal end. The distal end may comprise a port that permits discharge of a laser energy towards a tissue from an optical fiber located in the distal end. An exterior surface of the distal end may include a cauterization portion that permits discharge of a cauterization energy towards the tissue. In some aspects, the device includes an insulative portion that attaches the distal end to the elongated body and limits energy transfer therebetween. Related systems and methods are also disclosed.

Embodiments of the invention include a treatment device and corresponding treatment method for laser wound healing, the device and method making use of the simultaneous action of multiple laser types and laser wavelengths which are applied at human tissue. The treatment device generally includes a laser system and a hand-piece which is coupled to the laser system. The hand-piece is designed so that one or multiple laser beams are applied at relatively small spot and at a relatively high power level, and are surrounded by a relatively large spot of another laser beam with a relatively low power level. In a preferred implementation, the hand-piece is adapted to facilitate the emission of first and second laser beams together with a third laser beam which is delivered at a different spatial profile in comparison to the first and second laser beams.

A system and method are disclosed that use a flexible guide (flap) and a scanning method to control the delivery of light dose to a treatment area. This approach overcomes the non-reliable delivery of light dose with a flap that conforms to the target area. Dosimetry control can be improved through the use of a computer controlled motor to move the laser fibers at known speed over the target tissue. In some embodiments, treatment time is reduced and illumination of large surfaces is achieved by using multiple fibers to deliver the light simultaneously.
