A medical instrument includes a housing and a shaft coupled to the housing. The shaft has a proximal end and a distal end. An end effector assembly is disposed at the distal end of the shaft. The end effector assembly includes first and second jaw members. At least one of the first and second jaw members is movable from a first position wherein the first and second jaw members are disposed in spaced relation relative to one another to at least a second position closer to one another wherein the first and second jaw members cooperate to grasp tissue therebetween. The medical instrument also includes one or more light-emitting elements and one or more light-detecting elements configured to generate one or more signals indicative of tissue reflectance. The one or more light-emitting elements are adapted to deliver light energy to tissue grasped between the first and second jaw members.

The present invention relates to a light therapy device article of manufacture, system and method for providing light is delivered to the skin by means of one or more optical fibers in therapeutic dosages from light source in wavelengths of 614-624 nm, 668-684 nm, 751-772 nm, and 813-846 nm. The light source may be comprised from one or more light emitting diodes LED disposed on a flexible printed circuit board (PCB) and ferrule adapter assembly configured to deliver light to the skin directly of the patient from the light source disposed on the PCB adjacent a scalp surface. A control circuit operably connected to the PCB is adapted to provide energy to one or more zones of LEDs to address hair loss treatment regimen including splotchy balding, receding hairline balding, crown balding and total scalp surface therapy. Accordingly, a portable, cordless, hands-free light therapy device may configured as a headdress to be worn by the patient to minimize the negative psychological association of hair loss, while still providing effective hair growth treatment at an affordable price.

The invention provides a laser system and method for administering multiple beams of laser energy in tissue treatment applications. The system administers the beams simultaneously in a distribution pattern of spatially separated overlapping and non-overlapping regions on a tissue. The simultaneous administration and distribution pattern permit the beams to propagate within a tissue without producing the light scattering effects that characterize the sequential application of multiple laser beams to a tissue.

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.

A method for pigment removal from skin includes sensing properties of a pigmented area of skin with a camera, communicating the properties to a controller, and sending commands from the controller to a laser system to scan the pigmented area in a random pattern with laser beams of different wavelengths in accordance with the properties so as to remove a portion of pigment from the pigmented area.

The invention provides a method and apparatus for stimulating cellulite reduction using a femtosecond diode laser irradiation system. The system comprises a femtosecond diode laser capable of generating laser light that has a wavelength of 1000 nm-10,000 nm, a power level of 300 mw-5 W, and a pulse duration of less than 1 picosecond. A light-emitting device is coupled to the diode laser by means of flexible waveguide and is held over the skin. The device may be a handheld wand or an area pad comprising a plurality of light-emitting lenses on a surface of the pad. Laser setting controls are set to achieve a depth of photon absorption into the skin to reach subcutaneous adipose tissue.

The present invention relates generally to surgical lasers and more specifically to a laser beam control and delivery system that accurately and efficiently directs a laser beam into an optical fiber. The laser beam control and delivery system also provides additional functions, including a connection for a fiber tip temperature control system and a tissue temperature sensing system. The present invention also relates to a surgical laser system that has a high efficiency thermoelectric cooling system.

A method for treating a condition in a tissue, includes the steps: (1) providing a PS within the tissue; (2) irradiating the tissue containing the PS with a first light of a first wavelength; and (3) irradiating the tissue containing the PS with a second light of a second wavelength so as to treat the condition in the tissue, wherein: (a) the PS absorbs light at the first wavelength and the second wavelength; and (b) the second light is more strongly absorbed by the tissue than the first light or vice versa, so as to achieve a predetermined absorbed photon density gradient. An apparatus for conducting the method includes first and second light sources, a power supply, a focusing device, and a controller which adjusts light emission such that I(d)=I(1 at d=0)exp (.sub.eff (1)d)+I(2 at d=0)exp (.sub.eff(2)d).
