Title: Catheter introducer sheath
Inventor: PARKER FRED T
IPC: A61M25/08
Filed: 2001-03-23
Granted: 2009-10-06
Abstract: Introducer sheath having a flexible kink-resistant distal tip portion. A multilayer sheath structure is used, with an inner tube such as PTFE having a coil of wire wound therearound. A first length of outer tubing such as of nylon is inserted over most of the coil-wound inner tube in a manner exposing a distal length of coil-wound inner tube. A second length of outer tubing with a softer durometer than first outer tubing length is inserted over the exposed coil-wound inner tube and extends for a slight distance beyond the end of th e coil. During heat application, the outer tubing lengths are melted to bond t o each other and to flow between the spacings of the coil turns to bond to the roughened outer surface of the inner tube. The distal tip region correspondi ng to the second tubing length is flexible and is kink-resistant due to the coi l.

Abstract: A paper former comprises two wires which converge for defining a paper production gap and dewatering blades arranged in the paper production gap area in a paper producing direction and brought into sliding contact with one of the two wires so that a stock is dehydrated while being conveyed in a state put in the paper production gap. Each of the dewatering blades is shaped into a convexly curved surface configuration bent along a traveling direction of the wires and equipped with a wire sliding contact surface brought into sliding contact with the wire for guiding the traveling of the wire. Grooves are made in the wire sliding contact surfaces as a moisture run-off opening for running off moisture developing through the dewatering from the wire side.

Abstract: L'invention concerne un procédé et un système permettant de forer ou de découper un puits souterrain ou une formation (52) à l'aide d'un appareil de forage (5), d'un train de tige (55), d'une pluralité de concasseurs à impacts (100) pour matériaux solides, d'un fluide de forage et d'un trépan (60). Le procédé décrit dans cette invention est particulièrement utile pour le forage de puits destinés à l'industrie pétrolière et pour le découpage de formations dans l'industrie minière et dans l'industrie de forage de tunnels. Dans un mode de réalisation privilégié, plusieurs concasseurs à impacts pour matériaux solides sont introduits dans le fluide de forage et pompés par l'intermédiaire du train de tige de manière à appliquer un choc sur la formation au-delà du trépan. Au point d'impact, une portion importante en poids desdits concasseurs à impacts peut développer une puissance suffisante pour modifier, creuser et/ou fracturer la structure de la formation soumise aux chocs. La majorité en poids des multiples concasseurs à impacts peut présenter un diamètre moyen d'au moins 0,100 pouce, et peut modifier la structure de la formation à une profondeur d'au moins deux fois le diamètre moyen des particules composant la formation soumise aux chocs. La masse et/ou la vitesse des concasseurs à impacts peuvent être sélectionnées de manière à respecter la relation masse-vitesse dans le concasseur à impact respectif suffisant à modifier la structure de la formation. L'énergie rotationnelle, gravitationnelle, cinétique et/ou hydraulique développée à chacun des trépans permet aux concasseurs à impacts et au fluide de créer et de retirer des déblais de forage au-delà du trépan.

Title: Microneedles for minimally invasive drug delivery
Inventor: CHO STEVE T
IPC: B81C1/00
Filed: 2002-05-22
Granted: 2009-12-15
Abstract: The present invention provides a microneedle incorporating a base that is broad relative to a height of the microneedle, to minimize breakage. The microneedle further includes a fluid channel and a beveled noncoring tip. Preferably arrays of such microneedles are fabricated utilizing conventional semiconductor derived microscale fabrication techniques. A dot pattern mask is formed on an upper surface of a silicon substrate, with each orifice of the dot pattern mask corresponding to a desired location of a microneedle. Orifices are formed that pass completely through the substrate by etching. A nitride pattern mask is formed to mask all areas in which a nitride layer is not desired. A nitride layer is then deposited on the bottom of the silicon substrate, on the walls of the orifice, and on the top of the silicon substrate around the periphery of the orifice. The nitride layer around the periphery of the orifice is offset somewhat, such that one side of the orifi ce has a larger nitride layer. Anisotropic etching is used to remove a substantial portion of the substrate, creating a plurality of angular, blunt , and generally pyramidal-shaped microneedles. A subsequent removal of the nitride layer, followed by an isotropic etching step, softens and rounds out the blunt angular microneedles, providing generally conical-shaped microneedles. The uneven nitride layer adjacent the orifice ensures that the microneedles will include a beveled tip. Such microneedle arrays are preferably incorporated into handheld diagnostic and drug delivery systems.

Abstract: A method transmits data packets in a mobile radio system and corresponding mobile radio system. The method permits an immediate transmission of data packets to the receiver station along a new transmission path, after a handover of a connection along a transmission path, between a transmission station and a receiver station, to a new transmitting station. The new transmission station thus receives no information regarding the transmission status of data packets, which were transmitted before the handover of the connection.
