    摘要： A balloon arterial cannula and methods for filtering blood. The devices generally include a mesh for filtering blood flowing within a blood vessel, particularly within an artery such as the aorta, a structure adapted to open and close the mesh within the blood vessel, a means to actuate the structure, and a balloon occluder which typically includes a flexible material enclosing a chamber. The methods generally include the steps of introducing a mesh into a blood vessel to capture embolic material, adjusting the mesh, if necessary, during the course of filtration, inflating the balloon occluder to occlude the vessel upstream of the mesh, and thereafter deflating the balloon occluder and removing the mesh and the captured foreign matter from the blood vessel. Additionally, visualization techniques are used to ensure effective filtration.

    摘要： A detector comprising a plurality of densely packed x-ray detectors arranged into an array. Each detector preferably comprises a scintillator element which is optically coupled to a photodetector element, preferably with a fiber optic link. Each photodetector element is preferably optically separate from adjacent photodetector elements. The detector array preferably includes integral alignment means to align the scintillator elements with the photodetector elements. The scintillator array elements are preferably formed from materials which possess a fast response and a minimum afterglow time.

    摘要： A liquid flow regulator has a housing including an axial bore, an inlet, an outlet and a plurality of axial grooves opening endwise of the inlet and laterally of the housing into the bore. The grooves, which have different axial lengths, taper axially so that the cross-sectional area of each groove gradually decreases from the inlet to nothing at a point where the groove merges with the bore. An elastomeric stock fits within the bore. A plunger for expanding the sock radially outward into sealing engagement with the housing adjacent the bore is axially movable within the bore. Flow through the grooves and the bore is regulated by the axial position of the plunger and the minimum cross-sectional area of the tapered, axial grooves at the axial location where the sock seals the bore. Axial adjustment of the plunger sequentially opens and closes passage from the grooves through the bore to the bore outlet. The upper end of the plunger is provided with threads for engagement with internal threading in a passageway so that rotation of the plunger adjusts its axial position for control of the flow. The connection between the plunger and passageway threads is flexible so that the threads can be flexed out of engagement with each other when it is desired to axially and non-rotatively move the plunger to quickly place the regulator in a fully open or fully closed condition.

    摘要： A fluid infusion pump driver device for pumping fluid from the chamber of a disposable cassette. The pump driver includes a reciprocatable plunger which is driven by a stepping motor. The motor and plunger are coupled through a universal joint which provides a threaded connection translating the incremental angular movements of the motor into incremental linear movements of the plunger, and the plunger is coupled directly to the frame through a flexible leaf spring to prevent wear in the threaded connection from generating undue noise or creating accuracy problems.
