Patent EP-0299158-A1 (EP)
Inventor: LANDMAN MARK S
IPC: A61F2/958
Filed: 1988-04-30
Abstract: A medical device consists of an elongated catheter having a distal portion and a proximal portion, an inflatable balloon associated with the distal portion of the catheter and a valve member associated proximally with at least one lumen (30) communicating with the volume (V) of the balloon (14). In one embodiment, the valve member has a first position for connection of the first lumen (30) to a source of liquid for introduction into the balloon (14) and for connection of the second lumen (32) to atmosphere for venting of gas displaced from the balloon (14) by the liquid, and the valve member has a second position for connection of the first and second lumens (30, 32) to inflation/deflation means for flow of liquid into and rapidly out of the balloon (14) via both lumens (30, 32) simultaneously. In another embodiment, a valve member is associated proximally with the second lumen, the valve member having a first position for connection, of the second lumen to atmosphere for venting of gas displaced from the balloon by the liquid, and the valve member having a second position for closure of the second lumen. In both embodiments, the valve member is adapted for selective adjustment as required during use of the device between the first position for venting of gas from the device and the second position. Other embodiments include a stiffening member for varying catheter stiffness, and a catheter having proximal and distal portions formed of different materials. Methods of re-venting the balloon catheter, and varying catheter stiffness during use are also described.

Abstract: In order to regulate the pressure of a liquid in a pasteurizer or sterilizer operating at a high temperature, the valve comprises two chambers separated by a diaphragm integrally connected to a valve pin. 
<??>The pressure on the liquid to be treated side is at all times greater than that of the actuating air by virtue of the fact that the surface on which the compressed air acts is greater than that with which the liquid is in contact. This makes it possible to keep the installation sterile even in the event of faulty sealing of the diaphragm. 
<??>The valve is particularly suited to ultra-high-temperature sterilizers with direct injection of steam.

Abstract: A brake pressure control valve of this type has a first control piston which can be acted on by a first control pressure and a second control piston which can be acted on by a second control pressure. The two control pistons serve for actuating a combined inlet and outlet valve, via which a hydraulic inlet chamber can be connected to a working chamber. On such a brake pressure control valve the pressure level of the first control pressure must be equal to the pressure level of the second control pressure in order to prevent the second control piston taking over management of the pressure control when the first control pressure and the second control pressure are present. In order to allow the first control piston to be acted on by a first control pressure which is lower than the second control pressure acting on the second control piston, the invention proposes that the first control piston (25) and the second control piston (2, 9) be so arranged in relation to one another that the first active area (27) of the first control piston and the first active area (11, 12) of the second control piston (2, 9) are so opposed to one another that the first active area (11, 12) of the second control piston (2, 9) is also acted on by the first control pressure against the force of the second control pressure in the second control chamber (4) acting on the second control piston. The first active area (11, 12) of the second control piston (2, 9) acted on by the first control pressure is larger than the second active area of the second control piston (2, 9) acted on by the second control pressure in the second control chamber (3). <IMAGE>

Abstract: The invention relates to a process for transforming cells and to a recombinant DNA molecule for use therein. Said recombinant DNA molecule is a multifunctional linker comprising a DNA sequence which is homologous to a part of the receptor genome, an operator sequence and either a sequence which allows replication in a microorganism or a sequence which allows for integrative recombination in a vector. Preferably, said multifunctional linker also contains a gene whose expression can be detected in a microorganism, a gene whose expression can be detected in the receptor, a sequence which promotes recombination, and/or a hairpin structure at one or both ends. The transformation process uses donor DNA coupled to the multifunctional linker and allows for early success followed by further characterization of the donor DNA and its phenotypic impact.

Abstract: 2.1 A simple operating procedure is intended to enable telephone connections to be divided up into categories and stored. With certain types of connection, the operator is to be obliged to enter an identification code derived from the content of the call so that it can be recorded and in each case summed up. 2.2 With a specific authorisation class allocated to a connection device, the release of the latter when a connection is cleared is not enabled until predetermined identification codes are sent from the terminal to the switching installation. Identification codes of this type are stored in a specific memory and in each case identical ones summed up. The contents of this memory are then available for statistical analysis. 2.3 Thanks to the memory and evaluation devices connected to it, it is a simple matter to establish how often calls in each case with the same content have been received. These may, for example, be complaints, fault reports or other operational information which may require the instigation of specific measures. <IMAGE>
