  • Patent number: 8617142
    Abstract: A valve unit capable of being implanted in a patient and having adjustable performance settings, such as pressure settings and/or flow control, to regulate passage of a bodily fluid. A casing defines a port for the bodily fluid, and a valve mechanism positioned at the port includes a movable valve member. The valve unit further includes a rotor disposed at a first location in the casing and having an axle which turns about an axis of rotation. The rotor defines a plurality of arcuate, radially flat cam surfaces. Each cam surface occupies an arc about the axis of rotation. A spring arm unit is disposed at a second location in the casing having a cam follower arm in slidable contact with the cam surfaces of the rotor and having a resilient spring element applying a closing effect with the movable valve member to establish a performance setting for the valve unit.

  • Patent number: 7038449
    Abstract: A detection device, for detecting a strength of a magnetic field of an object, includes a housing having a center, a first end and a detection end. A permanent magnetic element is suspended above the center of the housing having a first magnetic field strength and an indicator. A biasing permanent magnetic element is disposed at the first end of the housing and has a second magnetic field strength for biasing the indicator toward the first end. A first distance is between the permanent magnetic element and the biasing permanent magnetic element so that a threshold magnetic field strength can be determined from the first magnetic field strength, the second magnetic field strength and the first distance. Thus, when the object is placed approximate to the detection end and the object magnetic field strength is greater than the threshold magnetic field strength, the indicator rotates toward the detection end.

  • Patent number: 6881210
    Abstract: A leveling device for determining the zero pressure point of an external draining system with respect to a patient is provided. The leveling device generally includes a body having a viewing element defining a field of vision, a reference point indicator spaced apart from the viewing element and disposed within the line of vision, which together define a line of sight, and a horizontal level indicator mated to the body and oriented parallel to the line of sight established by the viewing element and the reference point indicator. The horizontal level indicator indicates the horizontal alignment of the body with respect to a particular reference point viewed through the viewing element and indicated by the reference point indicator. The device optionally includes a reflector element adjacent to the horizontal level indicator within the field of vision, where the horizontal level indicator is visible through the viewing element via the reflector element.
