摘要： 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.

摘要： A cranial bolt secured to a skull of a patient includes a threaded portion and a lumen portion. Threaded portion has an inner surface forming a central passageway which extends throughout the threaded portion. The inner surface includes a connector mating with the lumen portion. The threaded portion has an outer surface having a plurality of threads for engaging a hole formed in the patient's skull. The lumen portion includes a stem portion that enters the central passageway and engages the mating connector. A fluid tight seal is formed between the inner surface of the threaded portion and the stem portion. At least two lumens are disposed through the stem portion and the base portion. The lumens have a proximal end opening outside the skull and a distal end opening inside the skull. One embodiment includes sensor lumens diverging from the centerline and another allows lumen portion to rotate independent of threaded portion.

摘要： 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.

摘要： 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. Sufficient rotation of the rotor to change the cam surface in contact with the cam follower alters the closing effect with which the valve member moves relative to the port and thereby alters the performance setting of the valve unit.

摘要： An acetabular prosthesis has an oblong geometry in which its dimensions in a first axis exceed those in a second axis that is normal to the first axis. The prosthesis has a superior, bone engaging surface with primary and secondary partial spheres that are merged together. The opposed inferior surface of the prosthesis includes at least one hemispherical cavity that is formed within the primary partial sphere. The primary partial sphere has dimensions that exceed the secondary partial sphere by less than or equal to about 5%.
