摘要： In one embodiment, an implantable prosthetic valve includes a body that defines an inlet end and an inlet orifice, the body being constructed of a flexible biocompatible material, an outlet that extends from the body and that defines an outlet end and an outlet orifice, the outlet being constructed of a flexible biocompatible material, and an inner passage that extends through the body and the outlet from the inlet orifice to the outlet orifice to enable fluid to flow through the valve, wherein the outlet orifice is open when the valve is in its natural unloaded state and is closed when fluid pressure is applied to the outlet from a position downstream of the outlet.

摘要： A flow differentiation scheme is disclosed for magnetic resonance imaging (MRI) of fluid flow in regions of turbulent flow. The flow differentiation scheme comprises the steps of (1) obtaining a first magnetic resonance (MR) image of the region, (2) obtaining a second MR image of the same region with an imaging parameter or imaging sequence altered, and (3) logically differentiating the first and second images with respect to flow to create a difference image. The process may be enhanced by superimposing one of the original images, upon an image that has been flow differentiated. As a result, a substantial amount of the static signal is suppressed producing superior angiograms of diseased and undiseased blood vessels. Additionally, the scheme can be used to image any fluid flow in any body or thing.

摘要： An article treatment system which provides improved solution mixing and concentration uniformity. The treatment system includes a container, a closure and a channel for guiding fluid flow. The treatment system is especially advantageous for use with effervescent tablets and for use in treating contact lenses. Cleaning and disinfecting of articles is improved by use of a tubular channel which guides upwardly gas and other components released from an effervescent tablet which is located at the bottom of the treatment container. The upward central flow through the channel induces a downward flow between the container walls, the exterior walls of the channel, and the article-retaining means and towards the bottom of the container.
