Apparatus for delivering stents to body lumens include one or more tubular prostheses carried at the distal end of a catheter shaft, a sheath slidably disposed over the prostheses, and a guidewire tube extending from within the sheath to the exterior of the sheath through an exit port in a sidewall thereof. A guidewire extends slidably through the guidewire tube. The sheath can be moved relative to the catheter shaft and the guidewire tube to expose the prostheses for deployment. Methods of delivering stents are also provided.

Flow reduction hood systems are described which facilitate the visualization of tissue regions through a clear fluid. Such a system may include an imaging hood having one or more layers covering the distal opening and defines one or more apertures which control the infusion and controlled retention of the clearing fluid into the hood. In this manner, the amount of clearing fluid may be limited and the clarity of the imaging of the underlying tissue through the fluid within the hood may be maintained for relatively longer periods of time by inhibiting, delaying, or preventing the infusion of surrounding blood into the viewing field. The aperture size may be controlled to decrease or increase through selective inflation of the membrane or other mechanisms.

A device (1) is designed for locating a region which is situated in a body (10). The device has a fluid-filled reservoir (30) which is closed off in a sealed manner by a displaceable plunger (32) and is connected to a hollow puncture needle (20). To measure the pressure prevailing in the fluid, the device has a pressure gauge (40). A signal converter (50) is used to convert a continuous pressure-measurement signal provided by the pressure gauge (40) into a form which is suitable for further processing. A synthesizer (60) is designed to process the converted pressure-measurement signal into a continuous sound signal which is representative of the pressure. If, during a displacement of the puncture needle (20), a needle point (21) reaches the anatomical cavity (15), the result is a readily perceptible change in the sound signal. The device records the pressure-measurement signal over the course of time.

An electro optical device includes a plurality of electro optical elements arranged on a surface of a first substrate, a plurality of positive diffractive lenses each for focusing a bundle of rays by diffracting light emitted from the each electro optical element, and a light shielding layer on which a plurality of apertures through which light diffracted by the each positive diffractive lens pass are formed.

In the pultrusion of reinforced plastic profiles in strand form, the strands of the reinforcement are brought together in a positioning device and subsequently embedded in the plastic. The pulling of the strands of the reinforcement through the positioning device leads to an unwanted contraction and uncontrolled positioning of the reinforcement in the plastic profile. The invention envisages forming the positioning device by multiple successive positioning means, of which at least some positioning means can be periodically moved forward in the direction of production and also moved back counter to the direction of production. As a result, there is an alternating tensioning and compression of individual regions of the reinforcement. This makes exact positioning of the reinforcement in the plastic profile possible and prevents contraction of the reinforcement.

An apparatus is described for foaming a slurry made of sand, water and a hydraulic binding medium by adding a foaming agent with a cylindrical vessel (2) for receiving the slurry and an agitator (7) revolving relative to the vessel about the vessel axis. In order to provide simple constructional conditions it is proposed that the agitator (7) comprises agitating units (10) distributed over the cross section of the vessel, which agitating units each consist of a rotor parallel to the vessel axis with agitator rods (14) between retainers (12, 13) on the face side, which rods are distributed over the circumference, are parallel to the axis and can be driven in an alternating manner in opposite directions.

A method of fabricating an oxide-nitride-oxide (ONO) layer in a memory cell to retain charge well in the nitride layer includes the steps of forming a bottom oxide layer on a substrate, depositing a nitride layer and oxidizing a top oxide layer, thereby causing oxygen to be introduced into the nitride layer. Another method includes the steps of forming a bottom oxide layer on a substrate, depositing a nitride layer and oxidizing a portion of a top oxide layer, thereby causing oxygen to be introduced into the nitride layer and depositing a remaining portion of the top oxide layer, thereby assisting in controlling the amount of oxygen introduced into the nitride layer. A further method includes the steps of forming a bottom oxide layer on a substrate, depositing a nitride layer, depositing a portion of a top oxide layer and oxidizing a remaining portion of the top oxide layer, thereby causing oxygen to be introduced into the nitride layer.

A reagent open mechanism of the luminescence measurement system comprises a triaxial actuator and a reagent dispensing nozzle which is driven by the triaxial actuator. A reagent cartridge where a reagent to be divided by the reagent dispensing nozzle is filled in a concave and the opening of the concave is sealed by an aluminum sheet can be set in. This reagent open mechanism comprises an open needle which is driven by the triaxial actuator and makes a hole in the aluminum sheet and a fixation block between the reagent dispensing nozzle and the open needle which arranges the reagent dispensing nozzle and the open needle in such location that the reagent dispensing nozzle or the open needle does not contact with a structure including the reagent cartridge in a Z-axis operation during opening time or reagent dividing and dispensing time.

The invention relates to a profiled structure,

• • elongated in a direction in which the structure has a length exposed to an airflow, and
  • transversely to which the structure has a leading edge (164) and/or a trailing edge, at least one of which is profiled and has, in said direction of elongation, serrations (28a) defined by successive teeth (30) and depressions (32).

Along the profiled leading edge and/or profiled trailing edge, the successive teeth (30) and depressions (32) extend only over a part of said length exposed to the flow over which the amplitude and/or spacing of the teeth varies monotonically except for the few teeth nearest each end of said part, a remaining part (280) of said length being smooth.
