Apparatus, systems and methods for fracturing calcium in an artery of a patient. Certain embodiments include a diode laser light source and an optical fiber. In particular embodiments, the optical fiber comprises a polymer or glass optical core, a cladding surrounding the polymer or glass optical core. The optical fiber can comprise one or more emission elements configured to emit electromagnetic energy from the laser light source. The electromagnetic energy can be transmitted through a fluid in the expandable member to fracture the calcium.

A surgical laser system includes an array of laser diodes that are configured to output laser energy, a fiber bundle, a delivery fiber, and a tubular sheath. The fiber bundle includes a plurality of optical fibers and has a proximal end that is configured to receive laser energy from the array of laser diodes. The delivery fiber includes a proximal end that is configured to receive laser energy from a distal end of the fiber bundle. The tubular sheath defines a lumen, in which at least a portion of the delivery fiber is disposed. The tubular sheath is insertable into a working channel of an endoscope or a cystoscope. A distal end of the tubular sheath is configured to deliver laser energy discharged from the delivery fiber into a body of a patient.

The present invention provides a laser system and laser handpiece and process for skin treatment. The system includes components for producing a continuous or pulse laser beam, and components for delivering a substance to the damaged region of skin. The system is designed to control and utilize the laser beam for damaging small volume of skin tissue and using a disposable tip to deliver a substance which is applied simultaneously or with some delay producing a combination of laser action with the action of a named substance at the same time.

A device and method for irradiating a target structure with laser radiation. The device has at least one laser light source and at least one optical element, by means of which the laser radiation is guided through a light outlet opening and focused at a focal point outside the light outlet. The optical element includes an arrangement of a convex mirror inside a hollow mirror, the mirrors being arranged such that laser radiation emitted from the laser light source enters the hollow mirror at least partially through an opening, and the laser radiation that passes through the opening hits the convex mirror, is deflected from the convex mirror to the hollow mirror, and passes through the light outlet opening from the hollow mirror.

System and method for generating patterns P of aiming and treatment light on target eye tissue (e.g. the retina) of a patient's eye. The system includes light sources for treatment and aiming light, a scanner for generating patterns of spots of the generated light, a controller, and a graphic user interface that allows the user to select one of several possible spot patterns, adjust the spot density and/or spot size, and apply patterns with fixed or varied density. The patterns can be formed of interlaced sub-patterns and/or scanned without adjacent spots being consecutively formed to reduce localized heating. Partially or fully enclosed exclusion zones within the patterns protect sensitive target tissue from exposure to the light.

A laser device for the selective treatment of acne comprising: a laser source (1) terminating in an optical collimator (2), which supplies a laser beam; said laser source (1) comprises a switch (13) which allows impulses of said laser beam with pre-defined duration to be transmitted; an opto-mechanical interface (3) comprising a lens (4) focusing the laser beam received from the optical collimator (2); an optical fibre (5) connected to said opto-mechanical interface (3); characterized in that said optical fibre (5) has a length greater than 15 m; and said device comprises a handpiece (10) connected to said optical fibre (5) where said handpiece (10) comprises an optical zoom system (11) which allows the diameter of the laser beam emerging from said handpiece (10) to be varied from 0.5 mm to 5 mm.

A laser or ultrasonic instrument is used to remove tissue during a surgery, such as to form one or more pilot holes in a vertebra or a window in bone. Where a laser is used, interrogative laser pulses can be used to obtain information, such as detecting depth or tissue type.

Provided are a laser tip, a laser treatment tool, a laser treatment device and a laser treatment system safely performing a surgery for a laser treatment and, if bleeding occurs, stopping the bleeding. A laser tip 70 is attachable to a laser radiation opening 63a provided at a tip end of a laser transmission tube 63. From the laser radiation opening 63a, laser light 57a is directed. The laser tip 70 includes a laser transmission tube attaching portion 71 detachable from the laser radiation opening 63a; a contact portion 72 contactable with a biological tissue, the contact portion 72 being provided to the front of the laser transmission tube attaching portion 71 in a direction in which the laser light 57a is directed from the laser radiation opening 63a, with an open space S being provided between the contact portion 72 and the laser transmission tube attaching portion 71; a coupler 73 coupling a part of the contact portion 72 and a part of the laser transmission tube attaching portion 71 to each other; the contact portion 72 having a reflective surface 72b at a rear end thereof, the reflective surface 72b reflecting the laser light 57a, directed forward from the laser radiation opening 63a, toward the coupler 73.

A device and a method for fractional skin treatment. The device employs two diffractive optical elements. One of the diffractive optical elements provides two coaxial laser beams and another diffractive optical element splits the two coaxial laser beams into a plurality of beamlets. A lens arranged to receive the plurality of the laser beams and to focus them in a skin treatment plane. The lens forms an image where each of the beamlets is imaged as a spot with a high intensity central area and a lower intensity area surrounding the central area.

Methods for treating dermal infection in an appendage of a mammal can include removing, such as by grinding off, a first nail portion of an appendage a mammal to expose a second nail portion of the appendage. A laser absorbing compound can be applied to the second nail portion of the appendage. The second nail portion can be irradiated with a laser of a treatment system to selectively heat the laser absorbing compound. Methods can also include applying a system for treating dermal fungal infection. A system can include a laser, an imaging unit for obtaining infection image data, and/or an alignment stage for receiving an infected portion of a mammal including the dermal fungal infection and aligning the infected portion of the mammal with the laser. A system can also include a control unit for controlling relative movement between the laser and the alignment stage.
