Method of incising and ablating living tissues and surgical laser devices
A method and laser surgical devices for surgical incising and ablating living tissues using laser beam and effecting enhanced surgical haemostasis concurrently with incising and ablating are disclosed. The method requires a surgical laser beam that is pulsed and is highly absorbed in living tissues and enhanced haemostatic action is achieved using along with the surgical laser beam energy, delivered in pulses, another separately controlled energy effecting haemostasis, by applying the second energy in any and every given spot of incising and ablating in a preemptive and focused manner, which minimizes haemostasis-related damage to surrounding tissues. In one embodiment a heated gas jet from a hollow core optical fiber transmitting the surgical laser beam is used. In other embodiments an ancillary laser radiation at a wavelength chosen specifically to minimize haemostasis-related damage to tissue is utilized for preemptive and controlled haemostatic effect.
TISSUE RESECTION WITH PRESSURE SENSING
Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.
PULSED LASER SYSTEM FOR DERMATOLOGICAL TREATMENTS
Disclosed is a pulsed laser system for dermatological treatment, including a light source suitable for emitting a light pulse beam and an optical amplifier system suitable for generating a laser pulse beam at a first repetition frequency. The duration of a laser pulse is between 100 femtoseconds and 100 picoseconds, the first repetition frequency is between 1 kHz and 10 GHz, each laser pulse having a quantity of energy less than or equal to 1 microjoule, and the pulsed laser system also includes a unit for temporally modulating the laser pulse beam and/or a unit for spatially modulating the laser pulse beam, the temporal and/or spatial modulation means being suitable for reducing the density of energy deposited on a surface to be treated and for generating a density of energy of between 0.0001 J/cm.sup.2 and 0.01 J/cm.sup.2.
PHOTO-THERMAL TARGETED TREATMENT SYSTEM WITH INTEGRATED PRE-CONDITIONING, AND AUTOMATIC TRIGGERING OF PHOTO-THERMAL TARGETED TREATMENT VIA MEASUREMENT OF SKIN SURFACE TEMPERATURE AND ASSOCIATED METHODS
A photo-thermal targeted treatment system for damaging a target embedded in a medium includes a controller and a photo-thermal treatment unit including a light source. The controller is configured for administering a treatment protocol using the light source at a preset power setting and a preset pulse timing setting. Also, a method for automatically initiating a treatment protocol using a photo-thermal targeted treatment system includes administering a cooling mechanism at a treatment location, monitoring a skin surface temperature at the treatment location and, when the skin surface temperature reaches a preset threshold, automatically initiating the photo-thermal treatment protocol. Further, a method for automatically terminating a treatment protocol using includes, during administration of the treatment protocol at a treatment area, monitoring a skin surface temperature at the treatment location, and when the skin surface temperature reaches a preset threshold, automatically terminating the treatment protocol.
AESTHETIC METHOD OF BIOLOGICAL STRUCTURE TREATMENT BY MAGNETIC FIELD
In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.
Method and device for optical ophthalmic therapy
Optical scanning system and method for performing therapy on trabecular meshwork of a patient's eye, including a light source for producing alignment and therapeutic light, a scanning device for deflecting the alignment and therapeutic light to produce an alignment therapeutic patterns of the alignment and therapeutic light, and an ophthalmic lens assembly for placement over a patient's eye that includes a reflective optical element for reflecting the light patterns onto the trabecular meshwork of the patient's eye. The reflective optical element can be a continuous annular mirror (e.g. smooth or with multiple facets) to image the entire trabecular meshwork, or a reflective optical element that moves in coordination with the deflection of the beam. Visualization of the alignment and therapeutic patterns of light on the eye can be implemented by reflection thereof off a visualization mirror that transmits a portion of light emanating from the trabecular meshwork.
AUTOMATED IMAGE-GUIDED TISSUE RESECTION AND TREATMENT
A system to treat a patient comprises a user interface that allows a physician to view an image of tissue to be treated in order to develop a treatment plan to resect tissue with a predefined removal profile. The image may comprise a plurality of images, and the planned treatment is shown on the images. The treatment probe may comprise an anchor, and the image shown on the screen may have a reference image marker shown on the screen corresponding to the anchor. The planned tissue removal profile can be displayed and scaled to the image of the target tissue of an organ such as the prostate, and the physician can adjust the treatment profile based on the scaled images to provide a treatment profile in three dimensions. The images shown on the display may comprise segmented images of the patient with treatment plan overlaid on the images.
