摘要： A valve unit (100) 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 (103) defines a port (102) for the bodily fluid, and a valve mechanism (140) positioned at the port includes a movable valve member (144). The valve unit further includes a rotor (120) 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 (122). Each cam surface occupies an arc about the axis of rotation. A spring arm (130) unit is disposed at a second location in the casing having a cam follower arm (132) 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： A detection device (100), for detecting a strength of a magnetic field of an object (10), includes a housing (102) having a center (104), a first end (106) and a detection end (108). A permanent magnetic element (110) is suspended above the center of the housing having a first magnetic field strength and an indicator (114). A biasing permanent magnetic element (116) 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： An acoustic monitoring system that is able to verify the success or failure of the positional adjustment of a valve without the need for additional energy during non-invasive reprogramming is provided. The acoustic monitoring system includes a programmer for generating a sequence of commands to adjust the valve mechanism, and for receiving acoustic signals for analysis, a transmitter to implement the command and adjust the valve, and a sensor for detecting an acoustic signal generated from the valve during execution of the commands. A method for using the acoustic monitoring system is also provided.

摘要： A shunt (10) includes a housing (14) having an inlet (16), an outlet (18) and a flow control mechanism disposed within the housing. A ventricular catheter (12) is connected to the inlet of the housing. The catheter has a longitudinal length, a proximal end (20), a distal end (22), and an inner lumen (24) extending therethrough. The inner lumen of the catheter includes at least two lumens (24',24'') at the distal end and has only one lumen at the proximal end. The catheter has one slit (30) and aperture (26) corresponding to each of the at least two lumens located at the distal end of the catheter.
