  • Patent number: 10952852
    Abstract: The invention provides medical devices, systems and methods for tissue approximation and repair and in particular to reduce mitral regurgitation by means of improved coaptation. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the cardiovascular system, heart, other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site.

  • Publication number: 20210000478
    Abstract: The present disclosure relates to repair devices configured for use in fixing or approximating tissues, such as cardiac valve tissues and particularly the leaflets of a regurgitant mitral valve. The repair device includes a shaft, a pair of proximal elements pivotally coupled to the shaft and extending from the shaft, and a pair of distal elements pivotally coupled to the shaft and extending from the shaft. The proximal and distal elements are configured so that targeted tissue can be grasped therebetween. The distal elements and/or the proximal elements include adjustable arms that can be extended and retracted to adjust the length of the gripping elements to provide more effective grasping of targeted tissues.

  • Patent number: 7630135
    Abstract: A method for assuring a blazed condition in a DMD device used in telecommunications applications. By meeting certain conditions in the fabrication and operation of the DMD, the device can achieve a blazed condition and be very effective in switching near monochromatic spatially coherent light, thereby opening up a whole new application field for such devices. This method determines the optimal pixel pitch and mirror tilt angle for a given incident angle and wavelength of near monochromatic spatially coherent light to assure blazed operating conditions. The Fraunhofer envelope is determined by convolving the Fourier transforms of the mirror aperture and the delta function at the center of each mirror and then aligning the center of this envelope with a diffraction order to provide a blazed condition.

  • Patent number: 7171068
    Abstract: A method to improve an extinction ratio of an optical device, the method includes positioning at least a majority of a plurality of micro-mirrors in an off-state position. A mirror assembly includes the plurality of micro-mirrors. The method also includes selectively positioning at least one of the plurality of micro-mirrors in an on-state position. In one particular embodiment, the at least one of the plurality of micro-mirrors positioned in the on-state position operates to improve an extinction ratio of an optical device.

  • Patent number: 6958841
    Abstract: Disclosed is a method for generating patterns to be used in a spatial light modulator having a plurality of pixels. The method includes generating an optical pattern to be placed upon the pixels of the spatial light modulator, applying the optical pattern to the pixels of the spatial light modulator, measuring the optical performance of the plurality of pixels having the optical pattern applied to it, comparing the measured optical performance to a target optical performance, and adjusting the optical pattern applied to the plurality of pixels to form another optical pattern that more closely achieves the target optical performance.

  • Patent number: 6831750
    Abstract: A method and system for indirectly measuring the tilt angle of micromirrors in a micromirror array. The method and system aims a coherent light beam through an aperture in a screen so that it reflects off of the surface of the micromirror array and creates a pattern of reflected light on the screen. The micromirror array is loaded with a pattern that has a uniform power spectral density (such as a random, aperiodic pattern or a frequency chirped sinusoidal spatial pattern) whereby certain micromirrors will be placed in the “on” position and the other micromirrors will be placed in the “off” position. By loading the micromirror array with a pattern having a uniform power spectral density distribution, the discrete nature of the resulting diffraction pattern is reduced and a pair of [sin(x)/x]2 patterns will be generated on the screen.
