Abstract: Disclosed are novel techniques for embolizing blood vessels which are particularly suited for treating vascular lesions via catheter delivery of an embolic composition.

Abstract: Disclosed are novel methods for embolizing blood vessels comprising delivering, via a catheter, an embolic composition comprising a biocompatible polymer, a biocompatible water insoluble contrast agent, and a biocompatible solvent. In one embodiment, the method is conducted during a single surgical procedure whereby a flow-arresting device is positioned and activated at the vascular site to be embolized, the embolic composition is injected, and the flow-arresting device is deactivated. In another embodiment, the method is conducted during a single surgical procedure whereby two embolic compositions, situated adjacent to one another, are injected at the vascular site to be embolized.

Abstract: The invention relates to an apparatus for the regeneration of active carbon comprising particularly:a hopper for introducing the active carbon;a reactor (7) delimited by an elongated shaped sheath;a continuous Archimedes screw (10) situated inside the reactor to transport the active carbon to be regenerated;structure for heating by resistances (8), arranged inside the sheath of the reactor;structure situated above the unload end of the reactor (19) and in communication with the reactor, particularly for removing the gases;a coffer into which the Arichmedes screw unloads;structure for communication with the reactor and situated on the one hand close to the input of the reactor and on the other hand along the reactor to regulate the pressure inside the reactor and to inject steam.This apparatus for regenerating active carbon enables the powder active carbon to be regenerated efficiently.
