Abstract: A multilumen catheter that maximizes the blood flow into and out of the patient's vasculature while also providing for passive and/or active perfusion of tissue downstream of where the catheter resides in the vasculature. The inventive catheter comprises a proximal end, a first distal and a second distal end with first and second lumens extending from the proximal end to each of these distal ends to provide for blood circulation within one blood vessel or between two different blood vessels. The second lumen, and any additional lumens so desired, may be positioned coaxially with or radially around the first lumen. Redirecting means is provided at a distal end of at least one of said lumens for directing blood in a direction generally opposite of the direction of flow through said lumen.

Abstract: A percutaneous cannula is provided that directs blood into a vessel of a patient. The cannula includes a main cannula portion and a tip portion. The tip portion directs blood-flow in a direction generally counter to the direction of flow through the lumen. The cannula is configured to prevent blood-flow exiting the distal end from immediately discharging against a wall of the vessel.

Abstract: An extracardiac pumping for supplementing the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart, and methods of using same. One embodiment of the intravascular extracardiac system comprises a pump with inflow and outflow conduits that are sized and configured to be implantable intravascularly through a non-primary vessel, whereby it may positioned where desired within the patient's vasculature. The system comprises a subcardiac pump that may be driven directly or electromagnetically from within or without the patient. The pump is configured to be operated continuously or in a pulsatile fashion, synchronous with the patient's heart, thereby potentially reducing the afterload of the heart.

Abstract: The present invention relates to a wrapper for individually packaging absorbent articles for personal hygiene, especially tampons. The wrapper of the present invention is provided with an opening means comprising a tear tape and a stopper, the tear tape is used for opening the wrapper and the stopper prevents the wrapper from becoming separated into more than two segments of wrapper material upon being opened.

Abstract: The present invention concerns a fastening system for fastening a first component to a second component with a precise separation. The present invention also concerns a method for fastening the first component to the second component with a precise separation, as well as an auxiliary apparatus for attaching the fastening system to the second component in order to place the first component on the fastening system. Preferably, the stud has an external thread and the support washer has a threaded hole matched to the external thread, so the support washer can be screwed onto the stud.

Abstract: To reduce the risk of hematoma formation, apparatus and methods for reducing bleeding from a cannulation site are provided. In one embodiment, the apparatus comprises a plug that applies pressure to the cannulation site. In another embodiment, the apparatus further comprises a hemostatic agent. In another embodiment, the hemostatic agent is flowable through a lumen of the plug to be deployed at the cannulation site.

Abstract: A vertical trench transistor has a first electrode, a second electrode and also a semiconductor body arranged between the first and second electrodes, there being formed in the semiconductor body a plurality of transistor cells comprising source region, body region, drift region and gate electrode and also contact holes for making contact with the source and body regions, contact being made with the source and body regions by means of the first electrode, and at least the bottom of each contact hole adjoining at least one drift region, so that Schottky contacts between the first electrode and corresponding drift regions are formed at the bottoms of the contact holes. The dimensions and configurations of the body regions or of the body contact regions optionally arranged between body regions and contact holes are chosen in such a way as to avoid excessive increases in electric fields at the edges of the contact hole bottoms.

Abstract: A power trench transistor comprises a semiconductor body in which a cell array and an edge region surrounding the cell array are formed. First edge trenches are formed within the edge region. The first edge trenches contain field electrodes and the longitudinal orientations of the first edge trenches run from the cell array towards the edge of the trench transistor.

Abstract: A multilumen catheter that maximizes the blood flow into and out of the patient's vasculature while also providing for passive and/or active perfusion of tissue downstream of where the catheter resides in the vasculature. The inventive catheter comprises a proximal end, a first distal and a second distal end. Lumens extending from the proximal end to each of these distal ends provide for blood circulation within one or between two blood vessels. At least one aperture in one of the lumens positioned near the proximal end provides for active perfusion of blood to the patient's vasculature downstream of where the aperture resides in the vasculature when the catheter is inserted into the patient for treatment. The inventive catheter may comprise a third lumen positioned entirely within the patient's vasculature, providing passive perfusion of blood to the patient's vasculature downstream of where the third lumen resides in the vasculature when the catheter is inserted into the patient for treatment.

Abstract: The system has at least two electronic units between which signals are transferred from a first electronic unit and a second electronic unit. The first electronic unit has a signal source. The second electronic unit has a signal sink. A signal to be transferred is converted into a line-independent electromagnetic wave with a transmitting unit and transmitted to a receiving unit. The line-independent electromagnetic wave is received with the receiving unit and converted into a reception signal.
