  • Patent number: 10709896
    Abstract: System and method for treating hemorrhoidal piles, addressing both cause and symptoms, by endoluminal/interstitial application of energy are disclosed. The dilated blood arteries in anal/rectal region are irradiated from inside the pile using (laser) energy for minimal pain/discomfort. The center of the pile is irradiated over a certain diameter, absorbing energy; and is denatured causing volume reduction. Central vessels located in the same diameter are obliterated immediately, relieving bleeding. During treatment, new connective tissue replaces the coagulated tissue. Closing inflowing arteries further shrinks piles in weeks to three months. Complications are highly diminished. A hand-piece and a fiber with a sharp distal tip are beneficial. Including an imaging system, (ultrasound imaging, optical coherence tomography) and an intelligent system to calculate necessary laser energy parameters help address each pile individually.

  • Patent number: 10238541
    Abstract: The procedures described herein may involve using one or more treatment beams to induce one or more therapeutic benefits. In some embodiments, a series of short duration light pulses may be delivered to ocular tissue at a plurality of target locations with a thermal relaxation time delay to limit the temperature rise of the target ocular tissue and thereby limit a thermal effect to only a desired portion of the ocular tissue. The thermal relaxation time delay may be roughly equivalent to a duration of a scan of the treatment beam between each of the target locations. Such procedures may be used to treat diabetic retinopathy, macular edema, and/or other conditions of the eye. The treatment beam may be delivered at each target location within a sufficiently short duration so as to produce a visual appearance of a treatment pattern on the ocular tissue of the patient's eye.

  • Patent number: 9980359
    Abstract: In a laser produced plasma (LPP) extreme ultraviolet (EUV) system, a plasma created from droplets irradiated by a laser pulse can become destabilized. The instability of the plasma can reduce the amount of EUV energy generated over time. While other systems seek to stabilize the plasma by varying a pulse width of the laser pulses, the systems and methods described herein stabilize the plasma by varying an intensity of the laser pulses. The intensity of the laser pulses is varied based on a comparison of the amount of EUV energy generated from current pulse to an expected amount of EUV energy. The intensity of the laser pulses can be varied on a pulse-by-pulse basis by an EUV controller that instructs a pulse actuator.

A probe is then used to measure an indicative property of the ablation target or of the pulsed laser projected on the ablation target. A control loop is used to optimize ablation effect by generating a feedback signal according to the measured indicative property, sending the feedback signal to a control unit, and adjusting an output parameter of the pulsed laser according to the feedback signal. The measured indicative property may be a size of the laser beam spot or a material composition. The ablation, the feedback and the adjustment may be performed dynamically.

  • Patent number: 9017316
    Abstract: A system and method of estimating a distance between the distal end of an optical fiber and treated tissue, to improve treatment efficiency, is provided herein. The estimation is achieved by modulating the numerical aperture of a light beam transmitted through the fiber to receive reflections from the tissue and distinguish them from other reflections in the fiber, and further by calculating the distance by comparing reflection intensities of beams having different numerical aperture values that illuminate the tissue over a very short period, so that tissue and environment conditions do not change much. Distance estimation may be carried out by modulating the treatment beam itself, or by a light beam transmitted between pulses of a pulsed treatment beam.

  • Publication number: 20150088108
    Abstract: Image-guided therapy of a tissue can utilize magnetic resonance imaging (MRI) or another medical imaging device to guide an instrument within the tissue. A workstation can actuate movement of the instrument via a probe driver, and can actuate energy emission and/or cooling of the instrument to effect treatment to the tissue. The workstation and/or an operator of the workstation can be located outside a vicinity of an MRI device or other medical imaging device, and drive means for positioning the instrument can be located within the vicinity of the MRI device or the other medical imaging device. The instrument can be an MRI compatible laser probe that provides thermal therapy to, e.g., a tissue in a brain of a patient. The probe driver allows for precise positioning, stabilization and manipulation of a probe.

  • Publication number: 20150051497
    Abstract: The present invention is a confocal scanning system for the multispectral imaging of fluorescence from a tissue sample based on the mapping of the spectral components of the fluorescence into the time domain using coated fiber tips disposed on multimode optical fibers. A fiber grating spectrometer based on two serial arrays of coated fiber tips disposed on multi-mode fiber, and delay lines between them provide spectral slices of the florescence. The coated fiber tips are arranged such that the shortest wavelength spectral components are reflected first and the longest wavelength components last. Fiber-based delay lines delay the reflections from each successive fiber tip such that they are uniformly separated in time, and in the order of its spectral wavelength number. The spectral bins are used to colorize the images to show the presence of abnormal tissue at cellular spatial resolution. A second scan with increased laser flux can destroy the diseased tissue revealed by the first scan.

  • Patent number: 8945102
    Abstract: A method for performing wavefront-guided laser surgery on a cornea includes the step of calculating a corneal flap configuration based upon collected anatomical information on an eye and wavefront data on a cornea of the eye. Such data may be collected by, for example, an aberrometer, although this is not intended as a limitation. The calculated configuration is transmitted to a processor in controlling relation to a corneal flap-cutting device. The flap-cutting device is used to create a corneal flap based upon the calculated configuration. A system for performing wavefront-guided laser surgery on a cornea includes a processor for receiving the anatomical information and wavefront data. A software package is adapted to calculate the corneal flap configuration and to control a corneal flap-cutting device to cut a corneal flap commensurate with the calculated corneal flap configuration.

  • Patent number: 8926600
    Abstract: Systems and methods for removing an epithelial layer disposed over a stromal layer in a cornea irradiate a region of the epithelial layer with a pulsed beam of ablative radiation. The ablative radiation is scanned to vary the location of the beam within the region in accordance with a pulse sequence. The pulse sequence is arranged to enhance optical feedback based on a tissue fluorescence of the epithelial layer. The penetration of the epithelial layer is detected in response to the optical feedback. The use of scanning with the pulse sequence arranged to enhance optical feedback allows large areas of the epithelium to be ablated such penetration of the epithelial layer can be detected.

  • Patent number: 8926601
    Abstract: An improved system for safe and efficient generation of plasmas and vapors bubbles with continuous wave radiations and low levels of power densities, sufficient to treat medical pathologies and to avoid the creation damage to healthy tissue is provided. Transmission means in different configurations are used to achieve a high absorption in water, which is able to initiate plasma with low levels of power density. Once plasma and vapor bubbles are formed, they absorb other wavelengths in addition to the one that initiated it. Other wavelengths, more efficiently generated by diodes or diode pumped lasers, are added into the beam to improve treatment efficiency. This modulated plasma produces fast tissue ablation and good hemostasis effect with minimal overheating of remaining tissue. After plasma and high-energy vapors are generated, only laser radiation that passes through the plasma bubble directly interacts with soft tissues.
