摘要:
An introducer deploys an endoluminal device in a distal location from a proximal location. The introducer comprises a retrograde portion, an anterograde portion axially moveable relative to the retrograde portion, a shaft having a distal tip and an anterograde sheath attached to the distal tip, and anchoring means in at least one of the retrograde portion or the anterograde portion for anchoring the device during deployment from its proximal end to its distal end. An inner sheath may be mounted concentrically over the shaft with the endoluminal device mounted concentrically over the inner sheath. The anchoring device may comprise an inflatable balloon mounted radially inside the retrograde portion, a tether, or an extended portion of the endoluminal device confined by a notch in the interface of two sheaths in the retrograde portion of the introducer, or may comprise a holder in the anterograde portion.
摘要:
A delivery system comprising an endoluminal device, an outer sheath that radially surrounds the endoluminal device, a pusher positioned at one end of the endoluminal device, and a linkage between the pusher and the outer sheath that coordinates movement of the outer sheath in a first direction with simultaneous movement of the pusher in a second direction opposite the first direction. This delivery system is particularly useful for endoluminal devices that foreshorten, and may comprise the outer sheath moving a first distance (d1) and the pusher moving a second distance (d2), where d2/d1 is approximately equal to the foreshortening ratio. The delivery system of this invention enables a foreshortening device, such as a vena cava filter, or stent, graft, or combination thereof, to be deployed with its end in a precise deployment location without foreshortening causing the end to move from the deployment location as the stent expands.

A device for removing a thrombus filter from a blood vessel is disclosed. A device in accordance with the present invention includes a shaft having a proximal end, a distal end, and a lumen extending therethrough, a wire having a first end and a second end, the wire being partially disposed within the lumen of the shaft, a portion of the wire extending beyond the distal end of the shaft and forming a loop, and a portion of the wire extending beyond the proximal end of the shaft.

Method and systems maintain historical printing device information from a plurality of printing devices, maintain historical actions performed on the printing devices, and maintain historical print image quality produced by the printing devices within a storage medium of a computerized device. These methods and systems determine which of the historical actions increase the print image quality and which of the historical actions decrease the print image quality, using the computerized device. The methods and systems output an action effectiveness report from the computerized device. The action effectiveness report indicates which of the historical actions increase/decrease the print image quality.
摘要:
“Resonance Force Sensor” has broad—and in some cases revolutionary—applications throughout aerospace, maritime, transportation, and industrial force sensing as a low cost, embedded, robust, self-calibrating strain-pressure sensor. Applications include but are not limited to structural load measurement, structural health monitoring, fluid and gas line pressure measurement, batch process manufacturing, and other force-sensing applications. When a complex structure, e.g. an aircraft or ground vehicle structure, is so instrumented, the present invention serves as the primary sensory component for a highly accurate, automatic, on-board vehicular weight and balance system. This sensor system can also be used in non-vehicular structures to measure axial, radial or flexural loading, and hence gravitational mass loading, of structural elements and structural systems.

An ESD protection system for I/O cells of an integrated circuit. The I/O cells of a bank of cells include a first type of I/O cells having ESD trigger circuits and a second type of I/O cells having ESD clamp devices. In one embodiment, the ESD trigger circuits of the first type are located at the same area of an active circuitry floor plan as the area in the floor plan for the ESD clamp devices of the I/O cells of the second type.

A motor controller automatically determines a motor input power setting based upon manually entered motor output values. The motor controller includes an interface and an input power determining module that determines the motor input power setting from the entered motor output values. A display portion provides a visual display of the determined motor input power setting to facilitate using the determined setting to control motor operation.
