    摘要： A spine implant, in particular a stabilization or distraction device, is provided with an adjustable length. The implant has first and second portions for coupling to a first bony portion of a first vertebra and a second bony portion of a second vertebra, respectively, where the second bony portion is located at an oblique angle to the first bony portion. The spinal implant permits movement between the first bony portion and the second bony portion and is adjustable to change an amount of said movement between said first bony portion and said second bony portion after the implant is implanted.

    摘要： An implantable fluid management device includes a catheter with an elongate proximal portion, a flexible distal portion, and a fluid passageway flowing therethrough. The distal portion includes a coil-shaped portion that defines a spiral having at least one turn. The distal portion of the catheter includes at least one pore in fluid communication with the fluid passageway of the catheter, which is located on an internal portion of the spiral. The positioning of the pore(s) on the internal portion of the spiral protects the pore(s) from obstruction or occlusion caused by tissue growing into or around the catheter.

    摘要： An implantable fluid management device is provided that includes a catheter having at least one wire running therethrough and coupled to a sensor disposed at a distal portion of the catheter. At least a portion of the wire is removably coupled to the catheter to allow a length of the catheter to be selectively adjusted, thereby providing a trimmable sensing catheter. The device can be used for a variety of medical procedures, but in an exemplary embodiment the device is a ventricular catheter that is used to drain CSF from a patient's ventricles.

    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： An artificial implantable heart assist system with an artificial myocardium employs a number of flexible, non-distensible tubes with the walls along their long axes connected in series to form a cuff. The tubes are sealed for purposes of inflation and deflation with either hydraulic fluid or pneumatic fluid. The cuff is placed around the natural heart. The inflation of the tubular segments provides that they have a circular cross-section, while in the deflated, or collapsed position without being fluid filled, they are essentially flat sheets. The difference in the perimeter length of the cuff in the plane of the tube short axis, arising from the fact that, inflated, each tube has a length along its perimeter equal to the diameter of the inflated tube, while deflated it has a length equal to the perimeter of the tube divided by two, provides for a contractile force. An energy converter is provided in the system for shuttling fluid between a compliant reservoir and the cuff in phase with the systolic and diastolic phase of the natural heart. This system is powered by an internal implanted battery, which can be recharged transcutaneously from an external power source.

    摘要： A paracorporeal respiratory assist lung is configured with an annular cylindrical hollow fiber membrane (fiber bundle) that is rotated at rapidly varying speeds. Fluid (for example, blood) is introduced to the center of the device and is passed radially through the fiber bundle. The bundle is rotated at rapidly changing velocities with a rotational actuator (for example, a motor or magnetic coupling). The rotation of the fiber bundle provides centrifugal kinetic energy to the fluid giving the device pumping capabilities and may create Taylor vortexes to increase mass transfer. Rotation of the fiber bundle increases the relative velocity between the fluid and the hollow fibers and increases the mass transfer. The porosity of the fiber bundle may be varied to enhance gas exchange with the blood. Alternatively, a rotating core may be used with a stationary fiber bundle.
