Laser energy delivery devices and methods are provided. A laser energy delivery device may include a housing, and a coupling is carried by the housing and adapted to couple to a laser energy generator. A sheath is carried by the housing, and the sheath includes a distal end adapted to be disposed in the subject. A plurality of transport members are carried by the sheath, and the plurality of transport members are adapted to receive laser energy at the coupling, transmit laser energy through the sheath, and deliver laser energy to the subject. A fluid-driven motor is carried by the housing and adapted to be driven upon receiving a fluid from a fluid source. A drive wire is carried by the sheath and eccentrically coupled to the distal end of the sheath, and the drive wire is adapted to be rotatably driven by the fluid-driven motor and rotates to eccentrically rotate the distal end of the sheath.

A steerable laser probe may include a handle, and inner bore of the handle, an actuation lever of the handle, a housing tube, and an optic fiber disposed within the inner bore of the handle and the housing tube. The housing tube may have a first housing tube portion having a first stiffness and a second housing tube portion having a second stiffness. The second stiffness may be greater than the first stiffness.

An ablation instrument (e.g., an ablation balloon catheter system) includes an elongate catheter having a housing with a window formed therein. An energy emitter is coupled to the elongate catheter and is configured to deliver ablative energy. A controller is received within the window and is coupled to the energy emitter such that axial movement of the controller within the window is translated to axial movement of the energy emitter and rotation of the controller within the window is translated into rotation of the energy emitter. The instrument includes a motor that is at least partially disposed within the housing of the catheter; a first gear that is operatively connected to and driven by the motor; and a second gear that is coupled to the energy emitter and is driven by the first gear to cause rotation of the energy emitter, while allowing the energy emitter to move axially.

Apparatus and techniques described herein can include delivery of a surgical laser beam for tissue excision or to facilitate hemostasis. The surgical laser beam can be generated, for example, using an ultrafast laser source. Such an approach can provide non-invasive treatment in relation to, for example, aerodigestive anatomy, such as for treatment of laryngeal, oropharyngeal, bronchial, and oral cavity tissues. Other generally available laser sources and their associated treatments may present various drawbacks making them less suitable for treatment for laryngeal, pharyngeal or bronchial pathologies, and use of the apparatus and techniques described herein can address such drawbacks.

A laser device for dermocosmetic, medical, or aesthetic treatments, comprising: A) a laser system comprising a lamp-pumped source; B) an optical fibre transporting the laser beam produced by said source; C) a handpiece or a scanner connected to said optical fibre, comprising a lens and mirror system projecting the image of the laser beam onto the area to be treated; characterized in that said optical fibre has a rectangular section and said image is rectangular.

A method of dermocosmetic laser treatment characterized by rectangular laser spots is also claimed.

It is a further object of the present invention a tracing kit, which allows the marking of a surface area, preferably of biological tissue, with a fluorescent or photosensitive substance invisible to light. Such an invisible and fluorescent or photosensitive substance absorbs the electromagnetic radiation with the proper wavelength emitted by the illuminator and reflects it in the visible spectrum.

A surgical laser system comprises a laser source configured to generate laser energy; a laser fiber optically coupled to the laser source and configured to discharge the laser energy generated by the laser source; a rocker arm configured to control an orientation of the discharged laser energy; and a controller configured to control a movement of the rocker arm in response to feedback of the discharged laser energy or to pre-defined settings of the laser source.

A manipulator, for use with a robotic control system, to maneuver an existing instrument (e.g., medical instrument) to a desired location within a target zone includes at least one controller, a rotation mechanism in communication with the at least one controller and being rotated about a first axis, a horizontal movement mechanism in communication with the at least one controller and being displaced along a first path, and a deflection mechanism capable of receiving a portion of the existing instrument. Such a deflection mechanism is in communication with the at least one controller and displaced along a second path in such a manner that causes deflection of a distal end (e.g., portion of an insertion tube) of the existing medical instrument.
