Combined liposuction method
The invention relates to combined liposuction methods and can be used in surgical interventions to remove local fat deposits in the lower third of the face and neck. The method includes a preoperative examination of the patient when one or more areas of the lower third of the face and neck of the patient are designated as liposuction areas constituting the operative field. The contour boundaries of the operative field and at least one operative access point are determined. Uniform infiltration anesthesia of the adipose tissue to be removed in the liposuction areas is performed. From a Nd:YAG laser radiation source with a wavelength of 1064 nm, a Nd:YAG laser radiation with a wavelength of 1064 nm in a pulsed mode with a frequency of 50 Hz, with a pulse duration of 300 s and a power of the predetermined value is supplied directly to the adipose tissue to be removed.
SPECTRAL DETECTION OF OPTICAL FIBER FLASHING EVENT
A laser tissue ablation system can include an optical fiber, with a distal end being extendible from an endoscope body of an endoscope. The optical fiber can deliver therapeutic laser light from the distal end of the optical fiber toward a target site, and receive return light into the distal end of the optical fiber. The laser tissue ablation system can include a sensor that can spectrally measure the return light. The laser tissue ablation system can include processor circuitry that can form a first determination, from the spectral measurement of the return light, whether flashing event light is present in the return light. The flashing event light can be generated when a flashing event occurs at the distal end of the optical fiber. The processor circuitry can generate, in response to the first determination, a flashing event data signal that indicates whether the flashing event has occurred.
LASER RESECTION DEVICE
An all-optical-fiber device configured to supply, to a target, laser radiation having characteristics sufficient for ablating a biological tissue in a manner that is consistent and competitive with the tissue removal geometry and volume provided by conventional electrocautery resection devices. The desired effect is achieved by configuring a facet of the optical fiber or an internal surface of the fiber's termination cap as a surface providing total-internal-reflection of light substantially at every point of such surface while having normals drawn to immediately adjoining surface portions be not parallel with respect to one another.
OPTIMIZATION OF BPH TREATMENT USING LEP (LASER ENUCLEATION OF PROSTATE)
Apparatus for the treatment of a target tissue with a laser beam in which the target tissue is immersed in a liquid medium within a body lumen. The laser device is configured to provide one or more laser pulses which are configured by a controller to have an energy sufficient to form one or more vapor bubbles in the liquid medium at the distal delivery end of the fiber. The one or more pulses are configured by the controller to: first, cause a vapor bubble to be formed distally of the distal end portion of the endoscope and around the distal delivery end of the optical fiber; second, cause a second bubble to be formed distally of the first bubble; and, third, inflate the second bubble as the first bubble has begun to collapse to expand an amount sufficient to displace a substantial portion of the liquid medium from the space between the distal delivery end of the fiber and the target tissue.
DEVICES AND THE USE THEREOF IN METHODS FOR ABLATION THERAPY
Various methods, systems, and devices for treating tissue ablation are disclosed. Some embodiments disclosed herein pertain to methods of treating tumors, systems used for irradiating tissue and tumors with electromagnetic radiation, components and devices of that system, and kits for providing systems used for irradiating tissue and tumors with electromagnetic radiation. In some embodiments, the system provides sub-ablative infrared radiation that is absorbed by nanoparticles. In some embodiments, the nanoparticles absorb the radiation converting it into heat energy. In some embodiments, though the infrared radiation itself may be sub-ablative, the heat energy generated by the nanoparticles is sufficient to cause thermal coagulation, hyperthermia, and/or tissue ablation.
Multiwavelength surgical laser
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.
DENTAL LASING DEVICE SYSTEM AND METHOD
A diode laser system having high-power diode(s) said high-power diode(s) producing laser outputs in a range of 0.1 to 25 Watts of power using optimum wavelengths via a single optical delivery fiber.
LASER SHAVING
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.
Probes having fiber taper and fluid collection channel for ophthalmic laser treatment
A treatment probe for treating an eye of a patient includes an elongate body that defines a handle and a treatment fiber that is housed within the elongate body. The treatment fiber is configured to deliver treatment light energy to the eye. A contact member is disposed on an end of the elongate body. The contact member has a contact surface for positioning on a surface of the eye, two side edges that are positioned on opposite sides of the contact surface, and a fluid channel. The contact surface conforms to the shape of the eye's sclera and the two side edges are shaped to direct fluid that is present on the surface of the eye toward the fluid channel when the contact member is moved laterally across the surface of the eye. The fluid aggregates within the fluid channel and contacts a distal end of the treatment fiber.
Multiple spot photomedical treatment using a laser indirect ophthalmoscope
A laser indirect ophthalmoscope (LIO) apparatus for photomedical treatment and/or diagnosis is presented. The LIO apparatus allows multiple spot ophthalmic surgery to be performed in a wider range of patient positions and less intrusively than currently available methods. The LIO apparatus utilizes a separate or integral beam multiplier that generates one or more optical beams via spatial and/or temporal separation, and an optical system that conditions and directs the one or more optical beams to a target to form a pattern. The LIO apparatus includes a headset, and is therefore wearable by the user (e.g., a physician).
