If the image fails to meet the one or more image acceptance criteria, the image may be re-taken. Based on the level of conformance of the image to the one or more image clarity criteria, the system may indicate that the macular pigment level cannot be provided with confidence, indicate that the eye likely has one or more cataracts, and/or calculate and provide the macular pigment content based on a correction factor, if needed.

  • Patent number: 9901485
    Abstract: An ophthalmic laser treatment apparatus includes: an irradiation optical system including an optical scanner for two-dimensionally scanning spots of a treatment laser beam and an aiming beam on eye tissue; a control unit to control the irradiation optical system to irradiate the treatment beam to a spot position based on an irradiation pattern of spots for treatment beam irradiation and based on an aiming rule associated with the irradiation pattern to irradiate the aiming beam to indicate the treatment beam spot position; and a movement unit to move an irradiation position of each beam. The control unit irradiates the treatment beam to a sequence of spots from a n-th position to a m-th position in association with the irradiation pattern, and then controls the movement unit and irradiates the aiming beam based on the aiming rule to a position different from the spot position just irradiated by the treatment beam.

  • Patent number: 9702842
    Abstract: Provided are an amperometric sensor and device for electrochemically quantifying nitrosothiol (RSNO), which is associated with storage and delivery of nitric oxide (NO) in the human body. The amperometric sensor for measuring a concentration of RSNO includes an electrode configured to measure an electric current generated by an oxidation reaction of NO, and a means configured to start and stop photo-induced decomposition of RSNO. Here, the electric current is measured by the oxidation reaction of NO before and after the photo-induced decomposition of RSNO. The amperometric sensor may measure separate signals of RSNO and NO, which are present in the sample at the same time, using one electrode, thereby preventing an inhibition action caused by NO during the measurement of RSNO. Also, the amperometric sensor is simple in structure and easy to manufacture and may be applied to manufacture of a small electrode, and thus may be developed as a sensor for in vivo measurements.

  • Patent number: 9610125
    Abstract: A laser system for body tissue treatment has laser source, control device, scanner, and handpiece with treatment head transparent to the laser beam. An incoming laser beam section enters the treatment head longitudinally. The treatment head has a conical output surface with a minimum and a maximum surface radius and a half opening angle for total reflection of the incoming beam section. The reflected beam section is refracted radially into an emerging beam section away from the treatment head through the output surface. The incoming beam section has at the output surface a mean diameter that is ?a difference of maximum surface radius and minimum scanning radius. A conical scanning surface as a part of the conical output surface extends from the minimum scanning radius to the maximum surface radius. The control device controls the scanner for scanning the conical scanning surface with the incoming beam section.

    Abstract: A tissue-removing catheter for removing tissue from a body lumen includes a tissue-removing. The tissue-removing element may be coupled to a first longitudinal body portion of the catheter body. The first longitudinal body portion may be rotatable along its length and relative to a second longitudinal body portion to adjust the angular position of the first longitudinal body portion relative to the second longitudinal body portion. An angular-positioning mechanism may be operatively connected to the tissue-removing element for rotating the tissue-removing element relative to the second longitudinal body portion about a rotational axis to adjust an angular tissue-removing position of the tissue-removing element, relative to the longitudinal axis of the body lumen, from an first angular tissue-removing position to a second angular tissue-removing position offset from the first angular tissue-removing position.

  • Patent number: 9387123
    Abstract: A system and method for treating ophthalmic target tissue, including a light source for generating a beam of light, a beam delivery system that includes a scanner for generating patterns, and a controller for controlling the light source and delivery system to create a dosimetry pattern of the light beam on the ophthalmic target tissue. One or more dosage parameters of the light beam vary within the dosimetry pattern, to create varying exposures on the target tissue. A visualization device observes lesions formed on the ophthalmic target tissue by the dosimetry pattern. The controller selects dosage parameters for the treatment beam based upon the lesions resulting from the dosimetry pattern, either automatically or in response to user input, so that a desired clinical effect is achieved by selecting the character of the lesions as determined by the dosimetry pattern lesions.

  • Patent number: 9162319
    Abstract: The invention relates to a method for removing material by means of a laser, wherein a sequence of laser pulses is generated and an area of material to be machined is irradiated with the sequence of laser pulses. Methods of this kind are used to cut a number of different materials. One problem with this method is that thermal or mechanical damage occurs in the surroundings of the area being machined and causes impairment of areas of material that are not being machined. The invention solves this problem by the pulse energy of a single pulse in the sequence of laser pulses being lower than the laser pulse energy required to produce material removal using an isolated laser pulse in the region irradiated with the single laser pulse of the sequence of laser pulses.

  • Patent number: 9039684
    Abstract: A system and method for controllably releasing radiation in percutaneous radiation treatment is provided. In a preferred embodiment, a laser is coupled to an optical fiber that is inserted below the skin or into a vascular lumen to a predetermined point. The fiber is connected to a source of electromagnetic radiation such as a laser, non-coherent radiation source, high power laser diode, LED, and an ultrasonic source. Radiation is then delivered to the treatment site while the fiber is simultaneously drawn out to the entry point. The fiber is manually withdrawn and during this time the radiation is administered in a manner appropriate for the vein being treating in regards to power or energy level. To maintain a constant proper energy density, the speed of withdrawal is measured and sent to a controlling mechanism. The controlling mechanism modifies the power emitted, pulse length or pulse rate to ensure that the vein or tissue receives a consistent dose of energy during manual withdrawal.
