Patent EP-0370158-A1 (EP)
Inventor: MARTIN GEOFFREY S
IPC: A61M5/158
Filed: 1989-01-19
Abstract: A flexible dual lumen catheter is provided for use especially in prolonged access for haemodialysis treatments and includes an elongate body (22) having side-by-side lumens (44, 46). Connecting tubes are attached to the lumens. The body has two portions, a distal portion for engagement within body tissue and a proximal portion extending between the connecting tubes and the distal portion. The distal portion has minimal rigidity for acceptance in the body tissue and the proximal portion has greater rigidity sufficient to minimize the risk of kinking during insertion and during normal use. A guide is also provided for use with the catheter. The guide has at least one weakness strip (74) extending longitudinally to permit the guide to be torn for removal from the catheter after insertion.

Abstract: The invention provides an apparatus for dilating a body cavity comprising an expandable member (11) having a normal position and a dilated position. In the normal position, the member defines a narrow generally elongate shape (Fig 2) for insertion in a body cavity. A means is provided to expand the member to its dilated position in which the member forms a hollow generally open ended elongate shape having a substantially continuous sidewall to dilate the body cavity. In one form the expandable member comprises a sheet of material (11) capable of being rolled into the normal position, and the means to expand the member comprises an inherent resilience of the sheet of material causing it to be naturally urged into a partially unrolled dilated position.

Abstract: A scanning tunneling microscope according to the present invention comprises a tip (21) for emitting spin-polarized electrons and a magnet (31) for applying a magnetic field to this tip. This tip (21) is constituted of a metal needle made of a tungsten and an EuS layer about 400 Å which is coated on the surface of the metal needle. This tip (21) is brought to such a close distance to the surface of the specimen (17) that tunnel current flows. A magnetic field is applied to the axial direction of the tip (21), a bias voltage is applied between the tip (21), and the specimen (17) and the tip (21) are made to scan the surface of the specimen (17). The tip (21) having a magnetic field applied to the axial direction thereof emits only spinpolarized electrons with the electron spins oriented in the axial direction. The spin-polarized electrons flow only in the area at the surface of the specimen (17) where empty states for the electrons having spins in the parallel direction are distributed. By detecting the flow of the electrons, that is, the tunnel current, it is possible to obtain the distribution of the electrons having upward or downward spins. The shape of the pointed end of the tip (21) is almost the same as that of a tip used in an ordinary STM. This makes it possible to measure the distribution of the electron spins with an atomic scale resolution.

Abstract: Dispositif de fixation d'une bague sur un arbre, comprenant un support annulaire qui présente un orifice avec un tronçon lamellé à rétrécissement conique. Ce tronçon est entouré d'une gorge cylindrique dans laquelle est disposée une douille de serrage présentant un orifice à rétrécissement conique inverse. Lorsqu'on pousse le dispositif préassemblé constitué par le support, la bague et la douille de serrage, le tronçon à orifice conique du support s'élargit, ce qui supprime le passage conique entre l'orifice de la douille de serrage et la circonférence intérieure de la gorge cylindrique. Le dispositif permet d'éviter que la bague soit soumise à des forces radiales susceptibles de la détériorer.

Abstract: A precision, highly reliable, positive displacement, pneumatic lubricator for pumping lubricant to a tool and work piece during machining operations; and for delivering compressed atomizing air thereto. The lubricator pumps lubricant substantially continuously at highly accurate, very low flow rates which can be minutely varied according to the needs of the user. The lubricator's piston (80) delivers one pulse of lubricant for each input air pulse which is supplied to the lubricator from a source of input air pulses (70). The lubricator includes internal check valves (130) for preventing back flow of lubricant into the lubricator's lubricant source, and for preventing back flow of pumped lubricant into the lubricator (148). The lubricator has an adjustable stop (82) which controls the stroke of its piston, and which thus controls the amount of lubricant which is pumped by each pumping stroke of its piston. The lubricator also has positive stops for the maximum and minimum adjustment of its adjustable stop. The positive stops prevent endless turning of the lubricator's adjustable stop in either direction with no change being made in the amount of lubricant pumped by each pumping stroke of its piston. The lubricator's valve body is made stackable so that one lubricator may comprise several valve bodies; each valve body being able to independently deliver lubricant and atomizing air to its respective tool and work piece through coaxial atomizing air/lubricant output lines. If the lubricator has more than one valve body, their lubricant input means, air pulse input means, air relief means, and compressed air input means are in fluid communication with each other.
