Abstract:
An endostapler delivery system includes a biasing mechanism to offset or counter forces generated by a stapling device and therefore prevent the stapling device from moving during the firing of the staple. The delivery system includes a catheter having at least one lumen extending there through for receiving the stapling device. The biasing mechanism is an expandable biasing cage having a dome or semi-circular expanded shape provided at the distal portion of the catheter. When expanded, the biasing cage does not block or occlude a vessel, thereby allowing blood flow to continue during the stapling procedure. The biasing cage may include a plurality of ribbons or strands that extend generally parallel to the blood flow when expanded in situ, a mesh or braided structure, or a plurality of ribbons or strands that extend generally parallel to the blood flow when expanded in situ and a mesh or braided structure placed over the plurality of ribbons.

Abstract:
This disclosure describes certain exemplary embodiments of a patient support having a plurality of vertically-oriented on substantially can-shaped inflatable bladders. In one embodiment, the patient support includes a plurality of pressure sensors positioned underneath the bladders. In another embodiment, the patient support includes a support layer positioned above the vertical bladders. In still another embodiment, the patient support includes one or more filler portions that are selectable so that the patient support may conform to bed frames having different deck configurations.
Abstract:
Systems and methods for analyzing structural test data are disclosed. In one embodiment, a method includes applying a sequence of loads to a test article, receiving raw test data indicative of the applied loads from at least one sensor operatively associated with the test article, receiving predicted test data indicative of the predicted loads on the test article, filtering out invalid test data, cycle counting to pair loads in the test data, performing a first fatigue damage computation based on the raw test data, performing a second fatigue damage computation based on the predicted test data, and comparing the first and second fatigue damage computations. The filtering, cycle counting, and performing of the first and second fatigue damage computations, and the comparison of the first and second fatigue damage computations, may be performed simultaneously using a spreadsheet program.
Abstract:
A method of monitoring a feature of a blast such as velocity of detonation (VOD) comprises the steps of providing a detonator 16.1 at a blast site 12. Prior to the blast, a blast control signal path 20, 18.1 is utilized to communicate blast control signals to the detonator. During a period following start of the blast, a blast feature signal communication path 18.1, 20 comprising at least part of the blast control signal path is utilized to communicate a blast feature signal relating to the feature to a remote blast feature monitoring station 26. The blast feature signal is generated by generating a monitoring signal in a conductor arrangement 18.1 connected to die detonator, utilizing a sensor outside of the housing of the detonator to sense changes in a blast feature monitoring parameter of the monitoring signal, and transmitting data relating to the changes to the station 26.
Abstract:
A rack for a drum set, comprising a X-shaped support member, wherein said X-shaped support member further comprises an upper partial X-shaped member and a lower partial X-shaped member; and further wherein, said upper partial X-shaped member contains at least one outwardly curving portion, and wherein said lower partial X-shaped member contains at least one outwardly curving portion, and one or more support legs, which may be removably coupled to said upper partial X-shaped member via a first sleeve coupled and to lower X-shaped member via a second sleeve.
Abstract:
A tissue stabilizer including an elongated arm, a collet, and a head-link assembly. The collet is disposed at a distal end of the arm. The head-link assembly includes a tube and a spreading mechanism. The tube forms an intermediate section and opposing arms each terminating at a tip. The spreading mechanism can adjust a lateral distance between the tips, and includes first and second articulating members each having a leg and a collet interface body. The first member further includes a female hinge feature, whereas the second member includes a male hinge feature differing from the female hinge feature. The legs of are mounted to discrete regions of the tube, and the male hinge feature is pivotably coupled to the female hinge feature. Automatic spreading of a lateral distance between the tips occurs in response to a compressive force applied to the collet interface bodies.
Abstract:
The present invention relates to a method for preparing a lithium vanadium phosphate material comprising mixing water, lithium dihydrogen phosphate, V2O3 and a source of carbon to produce a first slurry; wet blending the first slurry; spray drying the wet blended slurry to form a precursor composition; milling the precursor composition to obtain a milled precursor composition; compacting the milled precursor to obtain a compacted precursor; pre-baking the compacted precursor composition to obtain a precursor composition with low moisture content; and calcining the precursor composition with low moisture content at a time and temperature sufficient to produce a lithium vanadium phosphate. The lithium vanadium phosphate so produced can optionally be further milled to obtain the desired particle size. The electrochemically active lithium vanadium phosphate so produced is useful in making electrodes and batteries and more specifically is useful in producing cathode materials for electrochemical cells.
