摘要： An apparatus for providing continuous flushing of intravascular catheters. The apparatus consists of a small block having passages which define a continuously open path through which flushing solution is introduced into a catheter. A flow resistor is placed in the continuously open path in order to limit the flushing solution to a desired small amount. At least a portion of the block consists of a resilient sleeve which surrounds the flow resistor. The resilient sleeve provides a by-pass passage around the flow resistor. A disk placed in the by-pass passage cooperates with the resilient sleeve selectively opened to permit relatively large amounts of flushing solution to be introduced into the catheter when desired.

摘要： Methods and apparatus for controlling the movement of materials having different physical properties when one of the materials is a fluid. The invention does not rely on flocculation, sedimentation, centrifugation, the buoyancy of the materials, or any other gravity dependent characteristic, in order to achieve its desired results. The methods of the present invention provide that a first acoustic wave is propagated through a vessel containing the materials. A second acoustic wave, at a frequency different than the first acoustic wave, is also propagated through the vessel so that the two acoustic waves are superimposed upon each other. The superimposition of the two waves creates a beat frequency wave. The beat frequency wave comprises pressure gradients dividing regions of maximum and minimum pressure. The pressure gradients and the regions of maximum and minimum pressure move through space and time at a group velocity. The moving pressure gradients and regions of maximum and minimum pressure act upon the materials so as to move one of the materials towards a predetermined location in the vessel. The present invention provides that the materials may be controllably moved toward a location, aggregated at a particular location, or physically separated from each other.

摘要： Methods and apparatus for maintaining urinary continence in normally incontinent individuals. The present invention involves the non-surgical implantation of a bolus of ferromagnetic material into the bladder. The bolus of ferromagnetic material may comprise a biocompatible membrane, containing a ferromagnetic material. The bolus will normally rest at the juncture between the bladder and the urethra and will prevent the flow of urine from the bladder into the urethra. Essentially, the bolus serves as a seal between the urethra and the bladder. When it is desired to void the bladder, the ferromagnetic bolus is moved out of the intersection between the bladder and the urethra by positioning a magnet along the external surface of the person's body and manipulating the magnet until the desired movement of the bolus is accomplished. Movement of the magnet is sufficient to displace the bolus such that flow may be initiated from the bladder into the urethra.
