    Abstract: Improved/efficient fiber laser systems are provided for medical/cosmetic applications, comprising at least one pump source, optically coupled with at least one fiber laser. The fiber laser comprises an irregularly-shaped single-, double- or multiple-clad fiber of unconventional structure and geometry, and means for partially/completely reflecting the pump radiation, such as Bragg gratings. The fiber laser system further comprises at least one fiber optic delivery device optically coupled with the pump source, with the irregularly-shaped single-, double- or multiple-clad fiber laser, or with both, to convey laser radiation to a treatment site. The fiber optic delivery device comprises one or more waveguides, preferably optical fibers. The irregularly-shaped fiber laser and waveguides of the fiber optic delivery device have the same or different tip configurations to perform the treatment according to therapeutic needs. In a preferred embodiment, the fiber laser treatment system operating at 915±30 nm, 975±30 nm and/or 1550±40, comprises control means to select delivery of one, two or three output laser beams, and regulates their respective output powers.

    Abstract: A device configured to cut hair using laser light includes a handle portion and a shaving portion. The handle portion includes a battery and a laser light source. The laser light source is coupled to and configured to receive power from the battery. The laser light source is also configured to generate laser light having a wavelength selected to target a predetermined chromophore to effectively cut a hair shaft. The shaving portion includes a support and a single fiber optic supported by the support. The fiber optic has a proximal end, a distal end, an outer wall, and a cutting region positioned towards the distal end and extending along a portion of the side wall. The fiber optic is positioned to receive the laser light from the laser light source at the proximal end, conduct the laser light from the proximal end toward the distal end, and emit the light out of the cutting region and toward hair when the cutting region is brought in contact with the hair.

    Abstract: A multiwavelength laser-based intense light source is described having applications in incision, excision and ablation of soft tissues with minimal collateral tissue damage. The light source combines the output of a plurality of relatively low power laser sources, emitting radiation in the region of the electromagnetic spectrum bounded by approximately 350 nm to 450 nm, where the combined output may be coupled into a single fiber optic energy delivery device: a standard surgical probe. Spectral and spatial beam combining are used to produce an incoherent light source with relatively low average power at any given wavelength, but with high total power and superior M2 beam quality, targeting multiple chromophores in target tissue and tissue breakdown product chromophores for consistently high and target absorption without indiscriminant char interference throughout a surgical procedure.

    Abstract: An energy delivery device for administering tissue therapy includes a housing and an elongated body extending distally from the housing. The energy delivery device also includes a first lumen extending a length of the elongated body. The first lumen is configured to facilitate application of thermal treatment to a target region of tissue. A second lumen extends the length of the elongated body and is configured to facilitate infusion of hydrogels embedded with stem cells to the target region of tissue thermally treated. The energy delivery device further includes a third lumen configured to facilitate delivery of ultraviolet (UV) light to the target region of tissue for curing the hydrogels. A distal end of the elongated body is positioned in proximity to the target region of tissue for enabling successive introduction of the thermal treatment, infusion of the hydrogels, and delivery of the UV light.

    Abstract: A laser-based method and system for selectively processing target tissue material in a patient and optical catheter assembly for use therein are provided. The system includes a laser subsystem for generating an output laser beam. The system further includes a catheter assembly including at least one optical fiber having a proximal end coupled to the laser subsystem for guiding the output laser beam along a propagation path. The beam has optical and temporal properties and a predetermined selected wavelength. The catheter assembly is sized to extend through an opening in a first part of the patient and to a tissue material processing site within the patient. The catheter assembly includes a beam delivery and focusing subsystem which has an adjustable focal distance and disposed in the propagation path and that accepts the output laser beam and adjustably positions the beam into at least one focused spot on the target tissue material disposed within a second part of the patient at the site based on distance to the target tissue material from a predetermined point on the propagation path at the site for a duration sufficient to allow laser energy to be absorbed by the target tissue material and converted to heat to produce a desired physical change in the target tissue material without causing undesirable changes to adjacent non-target material disposed within the second part of the patient. The target tissue material is characterized by an absorptive coefficient. The predetermined wavelength is selected to achieve a penetration depth into the second part of the patient of approximately one millimeter or more.
