Abstract:
The invention provides apparatus and methods for mapping conduction pathways and creating lesions in the heart wall for the treatment of atrial fibrillation. The apparatus may include at least one epicardial ablation probe having a plurality of electrodes for creating a lesion. The apparatus and method facilitate the formation of a lesion which electrically isolates the pulmonary veins from the surrounding myocardium.
Abstract:
A system relating to sample analyzers, and more particular, to sample analyzers that are simple to operate and have a reduced risk of providing an erroneous result to a user. In some cases, the sample analyzer may be a portable sample analyzer that includes a disposable fluidic cartridge. The operators of the analyzers need not be trained.
Abstract:
An optical element for conveying scattered and image light to several detectors. The optical element may have the properties of a diffractive beam splitter and imaging lens. The detected light may be from an illuminated target. Further, there may be an optical element for conveying scattered light from a target via several zones to specific detectors, respectively. The latter optical element may include a multiple annular zone diffractive structure on a hybrid lens.
Abstract:
The present invention relates to the Composite Construction Building Panel now present in the prior art, it provides an improved Composite Construction Building Panel. The present invention allows for the Composite Construction Building Panel to be mounted on varying configurations, ranging from vertical, horizontal or overhead securely without requiring any elaborate construction processes. The present invention allows for the Composite Construction Building Panel to be manufactured using simple, relatively inexpensive process equipment that is already available. The present invention allows for the Composite Construction Building Panel to be a complete structural component with the insulating factors for thermal and sound, plus an exterior finished surface that will protect the foam panels and the interior of the building from the elements and also complete the aesthetically pleasing exterior surface so that no other surface need be installed to the exterior of the building. The present invention allows for the Composite Construction Building Panel to allow for windows, doors or any other thru-way to be installed easily and without excessive impact to the cost or labor.
Abstract:
A method of treating pelvic organ prolapse is provided. The method generally includes the steps of establishing a first pathway between the external perirectal region of the patient to the region of the ischial spine in tissue on one side of the prolapsed organ, followed by establishing a second pathway in tissue on the contralateral side of the prolapsed organ. A support member, which includes a central support portion and two end portions, is positioned in a position to reposition said prolapsed organ in said organ's anatomically correct location. The end portions of the support member are introduced through the respective tissue pathways, followed by adjustment of the end portions so that the support member is located in a therapeutic relationship to the prolapsed organ that is to be supported. An apparatus and kit for said treatment is further provided.
Abstract:
A VCSEL with current confinement achieved by an oxide insulating region and by an ion implant region. An annular shaped oxide layer is formed, and a gain guide ion implant is formed. The ion implant gain guide includes a central region having high conductivity. The VCSEL further includes first and second mirrors that are separated by an optical path of at least one wavelength. Furthermore, the oxide insulating region beneficially has a optical path of less than ¼ wavelength. The ion implanted spatial region is beneficially concentrically aligned with the oxide insulating region.
Abstract:
This disclosure is generally concerned with optical systems that employ guided-mode grating resonant reflector filters (“GMGRF”) to facilitate wavelength and/or polarization selectivity in the optical system. In one example, an optical system is provided that includes first and second tunable detectors. Each of the tunable detectors includes a GMGRF that is tuned to select a corresponding optical wavelength and/or polarization of an optical data channel, such that the optical wavelength and/or polarization associated with the first tunable detector is different from the optical wavelength and/or polarization associated with the second tunable detector. In this way, an array of tunable detectors can be employed to select some or all of the wavelengths and/or polarizations of an optical data signal having a plurality of data channels.
Abstract:
An apparatus and method are provided that enable T1 (or E1) telecommunications frames to be transmitted between T1 (or E1) telecommunications switches over a high bandwidth packet-switched network. The apparatus includes trunk interface logic and network translation logic. The trunk interface logic is coupled a central office switch via a central office switch trunk, and receives the telecommunications frames from the central office switch. The network translation logic is coupled to the trunk interface logic. The network translation logic translates the telecommunications frames into network packets that the telecommunications frame data may be transferred over the high bandwidth packet-switched network.
Abstract:
A system and method for surface rendering and for the display and analysis of arbitrary structures within the interior of a solid body is presented. The method uses as a starting point a voxel element which is known to be crossed by a surface of interest. The surface is rendered in a topologically consistent way by connecting encountered surface hits at each voxel face. A pair of voxel face hits, surrounding a vertex value exceeding the surface value are used to form a triangle, spun around a third articulating point in the interior of the voxel. Voxel faces sharing the surface hits are sequentially examined, and a set of approximation triangles is formed, to build a triangularization grid. The rendered surfaces are interactively displayed and analyzed for global structure properties.
