Inventor: RESZKA REGINA
IPC: A61K47/32
Filed: 2000-02-03
Abstract: The invention relates to a compressed air inhaler for the pulmonary application of a liposomal powder aerosol that carries active agents or is uncharged. The aim of the invention is to provide an inhaler by means of which the pulmonary application of especially liposomes that carry active agents is possible without forced breathing manoeuvres and by means of which the active agent can be transferred to the desired place of action in a sufficient amount without the active agent escaping. To this end, said compressed air inhaler comprises a receptacle (20) for the aqueous dispersion of liposomes. The liposomes carrying the active agents are dispersed in water in said receptacle. The receptacle is connected to an anatomising nozzle (1) and to a drying unit (17) via a device that doses liquids (19), whereby the drying unit can be an atomising chamber for spray drying the liposomes. An outlet (18) and a mouth piece are joined to said drying unit. The anatomising nozzle (1) is provided with separate supply channels (14, 16) for the compressed air and the dispersion of the liposomes (fig.1). The invention also relates to a novel powder aerosol consisting of liposomes or nanoparticles.

Abstract: L'invention concerne un système d'électrode implantable comblant l'espace, insérable dans une cochlée et comprenant une matrice d'électrodes allongée (30') et un positionneur (20). La matrice d'électrodes comporte de multiples contacts d'électrode (32) portés par un support allongé flexible, pouvant être inséré dans un des conduits en hélice, par exemple la rampe tympanique, de la cochlée. Le positionneur est un élément souple allongé, ayant une lumière ou un canal longitudinal (27) qui le traverse. Il est formé pour résider dans l'espace du canal cochléaire derrière la matrice d'électrodes et le combler de manière à positionner et maintenir les contacts d'électrode contre la paroi de la columelle de la cochlée. L'extrémité distale du positionneur est reliée amovible à la matrice d'électrodes en un point proche de l'extrémité distale de la matrice d'électrodes. Pour insérer le système d'électrode dans la cochlée, on insère un fil de stylet (154) dans le canal du positionneur, puis on guide et pousse doucement le positionneur dans la cochlée en étendant le fil de stylet. Ainsi, le positionneur inséré de cette manière dans la cochlée entraîne avec lui la matrice d'électrodes, permettant ainsi aux deux éléments - la matrice d'électrodes et le positionneur - d'être insérés ensemble dans la cochlée au cours d'une seule opération d'insertion. Le fil de stylet comprend une section plate (155) qui empêche le positionneur de tourner ou de se tordre pendant l'insertion.

IPC: E21B23/01

Abstract: A tool is provided for preventing the rotation of a downhole tool or rotary pump stator, the tool comprising a tubular housing and a jaw which is biased radially outwardly from the tool to engage the casing wall for arresting tool rotation and providing significant stabilization of a rotary pump. In doing so, the tool housing moves oppositely to rest against the casing opposite the jaw. The tool housing and the downhole tool are thereby restrained and stabilized by the casing wall. The tool's jaw is released by opposite tool rotation. Preferably, the jaw is biased outwardly from the tool housing to a casing-engaging position by a torsional member, housed along the axis of the hinge of the jaw. The tool is released from the casing by opposite tool rotation which increasingly compresses the jaw toward the housing, twisting the torsional member into torsion, which then acts to urge the jaw outwardly again. Overextension of the jaw during assembly is prevented using cooperating stops in the jaw and the housing.
