Title: Convertible catheter incorporating distal force transfer mechanism
Inventor: GERBERDING BRENT C
IPC: A61F2/958
Filed: 1999-02-18
Granted: 2008-06-10
Abstract: A method and apparatus for increasing the force transmission from a core wire to a more proximal portion of the catheter, and for directly providing column support at or near the side port of a convertible or rapid-exchange type of catheter. A core wire is typically attached to a proximal portion of a catheter, and extends distally therefrom through a lumen in the catheter. In accordance with the present invention, the core wire has a size and shape relative the lumen of the catheter such that the lateral movement of the core wire is restricted in a restriction region. By restricting the core wire at a distal location relative to the proximal catheter portion, the force transmission from the core wire to the proximal catheter portion can be increased. Further, in a rapid exchange or convertible type configuration, the restriction region may be placed proximate the side hole. By restricting the movement of the core wire adjacent to the side hole, the core wire can provide direct column support thereto reducing the likelihood of kinging or the like at that location.

Title: Time of flight mass spectrometer with selectable drift length
Inventor: HOYES JOHN BRIAN
IPC: G01N27/62
Filed: 2001-03-02
Granted: 2004-12-28
Abstract: A time of flight mass analyser 1 having a drift region 2, an ion packet generator 6, first and second ion reflectors 18,19 and at least one ion detector 20 is disclosed. The drift region 2 has an axis 3, an entrance 4 and an exit 5 and provides for a place wherein ions may be temporally separated according to their mass-to-charge ratios. The ion packet generator 6 injects packets of ions into the drift region 2 at the region's entrance 4 from a beam of ions by intermittently applying an electrostatic field such that the packets of ions enter the drift region 2 in an initial direction which is inclined to the direction of said beam of ions. The first ion reflector 18 is disposed at the exit 5 of the drift region 2 to reflect back towards the entrance 4 ions which are travelling towards the reflector 18 in the drift region 2. The second ion reflector 19 is disposed in juxtaposition to the first ion reflector 18 to reflect packets of ions back towards the first ion reflector 18 through at least a portion of the drift region 2 so that the packet of ions may be reflected to and fro between said first 18 and second 19 ion reflectors and undergo a number n of reflections at the second ion reflector 19. A detector 20 is disposed to detect at least some packets of ions reflected by the first ion reflector 18 which do not enter the second ion reflector 19. The number of reflections at the second ion reflector 19 may be selected by adjustment of an inclination of the initial direction to the axis 3.

Les bulles de gaz sont entraînées dans le liquide grâce à un dispositif du type venturi (12). Les membranes (20) sont de préférence compartimentées en groupes séparés (23), ce qui facilite le nettoyage et permet le maintien d'une densité de groupement élevée.

Abstract: A system (30) and a method may use variable-frequency power sources for sup-plying power to a load (36). The system and method use phase detection in order to automatically and substantially equalize the currents supplied to a load by each of the variable-frequency power sources, and to cancel a ripple component of the input current drawn by the system. First and sec-ond power sources (31, 32) supply power to the load. The power sources have a similar relationship between their respective variable switching frequencies of, respec-tively, the first and second power sources are locked to one another using phase de-tection to substantially equalize the power supplied to the load by each power source. The system and method are advantageously utilized to provide a power factor correc-tion front-end for a switch-mode power sup-ply. Power sources with non-linear and/or inverse relationships between power sup-plied and switching frequency can be used. In alternate embodiments power from se-ries power sources is equalized by equalizing voltages supplied by each power source to a load.

Title: Stable benzimidazole formulation
Inventor: LAHAV RAFFAEL
IPC: A61K9/28
Filed: 2000-06-21
Granted: 2010-09-28
Abstract: A stable composition with a benzimidazole derivative, such as Omeprazole, which does not contain a separating layer between the active compound and an enteric coating layer. Instead, the enteric coating layer is applied as a solution with a pH value of at least 6.5, and more preferably in a range of from about 7 to about 10, directly to the benzimidazole derivative substrate. This solution, with the optional addition of a plasticizer, can be directly coated onto the substrate without any necessity for an intermediate layer. Furthermore, in this pH range, the enteric coating is optionally applicable in an aqueous solution, thereby obviating the need for organic solvents for dissolving the enteric coating material. The resultant formulation maintains the stability of the benzimidazole derivative during storage and at the same time protects the product during passage through the acidic environment of the stomach. The problem of interaction between the enteric coat and the alkaline core is thus completely eliminated as the enteric coat at this stage is no longer acidic.

Abstract: A method and an apparatus for monitoring the condition of a fetus to assess a degree of risk of developing a permanent neurological condition are provided. A signal indicative of a fetal heart is processed to derive a degree of risk of developing a permanent neurological condition. The degree of risk of developing a permanent neurological condition indicates a likelihood that the condition of the fetus belongs to a class in a group of classes, where the classes in the group of classes are associated with pre-defined fetal conditions characterized by a measure of base deficit and a presence or absence of new-born encephalopathy. Data conveying the degree of risk of developing a permanent neurological condition is then released. In one example, a neural network is used to obtain data conveying a likelihood that the condition of the fetus belongs to a class in the group of classes.
