  • Patent number: 5167011
    Abstract: There is disclosed a method to coordinate the storage and retrieval of information with automated data processing equipment. A controlled vocabulary terms is used to link to other functions of storage/retrieval, telecommunications, and decision support. The controlled vocabulary is presented graphically to enhance the user interface and connections to the other functions are visually comprehensable as movements within, out of, or into the display screen. By unifying storage, retrieval and communication around the controlled vocabulary the context of information is enhanced and the effort in inputting, outputting, sending, and receiving information is reduced.Further, the device can be constructed as being goal or outcome directed.

  • Patent number: 5059205
    Abstract: A filter device positionable within a blood vessel for trapping blood clots in that vessel, the filter device comprising a head with a plurality of divergent legs each secured at its proximal end, to the head, each leg having a hook arranged at its distal end. The distal end includes a reversely bent portion of the leg which itself is bent radially outwardly, ending in the shape of a sharp point. The reversely bent portion of the leg comprises a pad to minimize the depth of penetration of the hook.A further embodiment of the leg shows a radially outwardly directed radius of curvature to create a conical configuration to the filter assembly, while distributing the stress concentration along the length of the bend, so that the elastic limit of the material, stainless steel in this embodiment, is not exceeded, and which permits compact delivery of the filter, and adequate radially directed force to permit slight hook penetration of a vessel wall.

  • Patent number: 5002059
    Abstract: The present invention relates to an ultrasonic imaging catheter having an open proximal end and a closed distal end. The closed distal end contains a septum and a situs for targeting the septum. A fluid filled syringe may be insertable though the situs and the septum to fill a chamber defined by the catheter sheath and the septum, with ultrasonic transmission fluid. The chamber subsequently receives an ultrasonic image generator and receiver within the fluid filled chamber. Injection of fluid through the septum eliminates the likelihood of air bubbles forming within the chamber which otherwise damages the ultrasonic images generated thereby when that chamber is filled with fluid through the proximal end of the catheter sheath.

  • Patent number: 4934212
    Abstract: A strain wave gearing device comprising a ring gear having internal axially extending teeth and a strain gear produced from a strain gear blank having constant thickness to the cylindrical and diaphragm portions. The cylindrical portion has external axially extending teeth extending around an annular portion adjacent the open end of the strain gear for engaging with the internal teeth of the ring gear (the number of external teeth on the strain gear being different than the number of internal teeth on the ring gear) and a wave generator is located within and matingly engages with the strain gear. The diaphragm portion is reduced in final thickness from the uniform blank thickness to about one-half the blank thickness by machining, after the strain gear has been produced from the blank. The wave generator adapted to be rotatively driven relative to the strain gear whereby relative rotational movement will occur between the strain and ring gears.

  • Patent number: 4851612
    Abstract: A protective enclosure assembly for an electrical outlet having plug receptacles, having a baseplate which fits around the receptacles. The baseplate has a peripheral edge with notches arranged into two of the opposing edges. A transparent housing fits over the baseplate. The housing has a set of full tabs extending from one lower edge thereof, and a main locking and two small tabs extending from its opposite edge.A set of slots are disposed through the housing wall, one slot between adjacent tabs on the multiple tab wall. The housing covers the receptacles when the housing walls are "pinched" so as to flex inwardly the walls, enabling the multiple tabs to mate with the notches on one edge of the baseplate, and enabling the one tab on the opposing wall of the housing to scamp into a notch on the opposing edge of the baseplate edge.The baseplate then safely encloses any electrical cords plugged into the plug receptacles, the cords extending through the slots in one of the sidewalls of the housing.
