摘要:
A liner assembly for a pipeline section having at least one junction with a lateral pipe, the liner assembly comprises an outer tubular liner having an opening therein generally coinciding in position with each junction when the liner assembly is positioned with the pipeline section and an inner malleable inflatable bladder assembly positioned longitudinally within the tubular liner, said bladder assembly being inhibited from over-expanding during positioning and inflation of the liner assembly within the pipeline section.

The application relates to a method for producing a catheter (1) with a proximal portion, a distal portion, and an expandable element (2) arranged in the distal portion, wherein the expandable element (2) can be brought from a contracted state into an expanded state by the delivery of a fluid, and a removable protective device in the form of a tube (5) is arranged around the expandable element (2) in the contracted state, and wherein the tube (5) is turned back over the expandable element (2) and is guided with the catheter (1) through one or more nozzles (6), wherein the tube (5) is stretched and the internal diameter of the tube (5) decreases. The application further relates to a corresponding catheter (1) with a tube (5) pulled over the expandable element (2). The application permits the provision of a catheter (1) which is characterized by a particularly small cross section in the area of the distal portion.

Le dispositif d'expansion radiale d'un manchon élastomère (1) comporte un organe de guidage cylindrique rigide (2) et au moins deux jeux d'organes d'expansion radiale tubulaires rigides emboîtables les uns dans les autres (3, 4) ayant un diamètre interne supérieur à un diamètre externe de l'organe de guidage (2).
摘要:
A fiber bundle is wrapped with a tape by helically and entirely winding the tape around the bundle, while applying a constant longitudinal tension to the bundle; and thereafter unwinding and removing the tape from its last turn to gradually expose the bundle towards its basal end, while inserting the exposed portion of the bundle gradually into a cylindrical protector. The method keeps constant the outer diameter of the bundle by adjusting the tape tension, even if the bundles are composed of varied numbers of fibers in one protector, so that a wider use of the protector is realized. In the method, the wrapping operation does not produce any damaged fibers from which a fluid such as blood leaks in a hollow fiber apparatus, and no later adjustment is necessary for the wrapped bundles, thus improving the production efficiency.
