Abstract: A small diameter dilatation catheter (10) for coronary angioplasty is achieved by providing first and second elongated flexible, thin-wall tubes (12, 20), each having one or more reinforcing wires (40, 44) encapsulated in the walls thereof and dimensioned such that the second tube (20) may be coaxially disposed within the lumen (18) of the first tube (12). The preferred material from which the two tubes (12, 20) are fabricated is polyimide. The longitudinally extending reinforcing wires (40, 44) provide the requisite "pushability" characteristics required by PTCA dilatation catheters. The balloon or inflation member (30) has its proximal end (32) bonded to the outer surface of the outer tube (12) and its distal end (34) bonded to the outer surface of the tube (20). Inflation fluid then may be perfused between the I.D. of the outer tube (12) and the O.D. of the inner tube (20).

Abstract: Les comprimés métallurgiques en poudre décrits, qui sont produits en continu, sont fabriqués à partir d'une poudre métallique (4) placée dans une région de consolidation de poudre à section décroissante (2) d'un moule de formage (1). Le moule est conçu pour pouvoir subir des vibrations radiales ultrasonores autour de la région de consolidation, de façon à assurer une compression radiale de la poudre. La poudre est progressivement densifiée au fur et à mesure qu'elle avance dans le moule, grâce à la construction tronconique de la région de consolidation, et sort du moule avec une densité suffisante pour permettre sa manipulation et un traitement ultérieur.

Abstract: On décrit un procédé de conversion de pénicilline-1-(R)-sulfoxyde(s) et/ou de céphalosporine-1-(R)-sulfoxydes en solution, en leurs 1-(S)-sulfoxydes correspondants. Le procédé consiste à traiter ledit 1-(R)-sulfoxyde avec une quantité d'un anhydride d'acide suffisante pour convertir au moins une partie dudit 1-(R)-sulfoxyde en son 1-(S)-sulfoxyde correspondant. On décrit également un procédé de production de 1-(S)-sulfoxyde à partir de la pénicilline et/ou de la céphalosporine par l'oxydation de la pénicilline ou de la céphalosporine au moyen d'un agent d'oxydation, et simultanément ou ultérieurement par l'addition d'une quantité d'un anhydride d'acide suffisante pour convertir au moins une partie du 1-(R)-sulfoxyde en son 1-(S)-sulfoxyde correspondant dans un délai compris entre 5 minutes et 2 heures, afin de maintenir un niveau pH supérieur à 3,5 et de produire une solution du 1-(S)-oxyde correspondant. Dans un mode de réalisation préféré, un tampon est incorporé à la solution afin de permettre une régulation supplémentaire du pH pendant la réaction. Le procédé permet d'obtenir des rendements exceptionnellement élevés de 1-(S)-oxydes de grande pureté, et est plus sûr que la plupart des procédés industriels dans lesquels l'utilisation et le maniement de l'acide peracétique à 40 % sont nécessaires.
