Title: Apparatus for performing broncho-alveolar lavage and method of using
Inventor: ENHORNING GORAN E
IPC: A61M1/00
Filed: 1996-02-09
Abstract: An apparatus for performing broncho-alveolar lavage and a method of using the apparatus using relatively low known pressures which may avoid damage, such as overexpansion and rupture of airways and alveoli, when too high a pressure is used.  The apparatus includes a closed barrel device for receiving a predetermined quantity of broncho-alveolar lavage fluid, apparatus for applying a predetermined pneumatic pressure upon the upper surface of the broncho-alveolar lavage fluid, and a catheter, the distal end properly positioned in the portion of a patient's lung to be lavaged.  The pressure applying apparatus includes a closed compartment forming an air chamber, and a fluid containing first bladder mounted within the air chamber, the air chamber being in communication with the closed air space in the barrel device above the lavage fluid.  The hydraulic pressure applying device is a second bladder in an open container in fluid connection with the first bladder.  In use to infuse the desired portion of the lungs with broncho-alveolar lavage fluid, it is now only necessary to raise the open container to a certain height above the closed container. Fluid will flow from the second bladder to the first bladder pressurizing the air chamber.  As this chamber is connected with the chamber in the syringe, the broncho-alveolar lavage fluid will be pressurized to this extent and be forced through the catheter into the lung.  When the lavage fluid is aspirated into the syringe, the open container is lowered below the level of the closed container.  The broncho-alveolar lavage fluid will now be aspirated from the lungs.  This process is repeated several times to give the broncho-alveolar lavage fluid a high concentration of cells and chemical agents.

Abstract: A storage rack for small articles having an elongated support bar in which are formed a multiplicity of transverse slots along the length thereof.  Each slot extends from the front to the back of the support bar and each slot is open at its top but closed at its bottom.  A bottom ledge extends outwardly of the slots at the front and rear edges of the support bar.  A tenon on the support bar extends upwardly into the slots.          Undercuts are formed in the support bar creating overhangs on opposite sides of each slot above the tenon.  A multiplicity of retainer loops formed of a strip of a tough, resilient, abrasive-resistant resin are provided.  Each retainer loop has a bite portion positioned outwardly of the front edge of the support bar and two legs positioned in one of the slots with each leg engaging an overhead on an opposite side of its slot and the bottom ledge.  A downwardly opening notch is formed in each leg with the notch fitted over and receiving the tenon to preclude withdrawal of the loops forwardly through the slots.

Abstract: In a process for drying material in a drying system, a first current of heated gas is supplied to a first dryer from a corresponding first combustion chamber.  Material to be dried is exposed to the first current in the first dryer.   The dried material is separated from the first current of heated gas.  The first current of heated gas is split into a first stream of heated gas and a second stream of heated gas after the dried material has been separated.   The first stream is introduced into the first combustion  chamber  so  that  the  gas  generated  in  the  first combustion chamber and the first stream are combined to constitute the first current of heated gas.  At least a portion of the second stream is introduced into the second combustion chamber.  A second current of heated gas is supplied to a second dryer from the second combustion chamber.  The portion of the second stream introduced into the second combustion chamber constitutes a portion of the second current.   Material to be dried is exposed to the second current in the second dryer.  The dried material is separated from the second current.

Title: Embolic coils with offset helical and twisted helical shapes
Inventor: MARIANT MICHAEL J
IPC: F16F1/04
Filed: 1996-04-25
Abstract: This is a surgical device that, in particular, is for forming a vasoocclusion or-embolism.  Typically, it is a helically wound coil in which the helix is wound in such a way as to have multiple axially offset, longitudinal or focal axes.  Another important facet of the invention is the presence of small diameter secondary coil windings adjacent large diameter coil windings.  The device is sufficiently flexible and small that it may be delivered to a site within the vasculature of the human body using a pusher and a catheter.  The device is generally linear when within the catheter but relaxes to form the multi-focal form after delivery from the distal end of the catheter lumen.  Various mechanical connections may also be used to discharge the inventive coil from its pusher.  Similarly, the coil may be attached to a pusher using a sacrificial joint, which sacrificial joint is dissolved by imposition of a small voltage within the human body.  The device may be used alone or in conjunction with other coils or with a fibrous thrombotic attachments or the substrate to localize subsequent infusion of tissue adhesives, other particulate embolization devices, or chemotherapeutic agents in abnormal blood vessels and tissues.

Title: Method for the reliable determinaton of the distance of the conductive reaction track from a functional surface moving relative to the reaction track and a sensor for performing the method
Inventor: ELLMANN SIEGFRIED
IPC: G01B7/14
Filed: 1996-07-11
Abstract: In a method for measuring a distance between a conducting reaction track and a functional surface moving relative to the reaction track a sensor with two signal transmitters is provided on the functional surface. An alternating field is generated in the sensor. The alternating field changes as a function of the distance between the conducting reaction track and the functional surface.          Each of the two signal transmitters detects the changes of the alternating field as distance information. Each signal transmitter produces decoupled distance information values.    These decoupled distance information values are processed in separate distance measuring channels to provide processed signals. The processed signals are constantly fed to and compared in a comparator.  A distance information signal is emitted only when the processed signals of the separate distance measuring channels are identical within a predetermined tolerance range.
