Abstract: L'invention concerne un dispositif et un procédé pour traiter l'infarctus du myocarde. Ce procédé consiste à chauffer, de manière sélective, la cicatrice de l'infarctus pour réduire la taille de la zone du tissu infarci (18) en provoquant le rétrécissement du tissu cardiaque (10), à raidir la partie molle du tissu infarci, à réduire la tension de la paroi systolique ventriculaire, et à augmenter l'efficacité de pompage globale du coeur infarci (10) en supprimant un anévrisme ventriculaire, le cas échéant. La chaleur peut être appliquée à la cicatrice de l'infarctus, ou induite dans cette dernière. Il est également possible d'appliquer une force pour favoriser la réduction de la taille de la cicatrice (18) à l'aide du dispositif, selon l'invention, qui comporte un élément chauffant (24) et des pinces (26) de type ciseaux, pour serrer ensemble les deux parties de la cicatrice infarcie.

IPC: A01G9/12
Filed: 1999-07-02
Abstract: A supporting frame for a portion of a stem of a plant comprises a generally arc-shaped guiding member, two spacers projecting away from an inside concave surface of the guiding member, and a pressing member pivotally connected to the spacers. The guiding member, the pressing member and each spacer define a U-shaped cross-section for permitting insertion of the portion of the stem therein. The pressing member is deformable between an open position and a closed position. In the open position, the pressing member is away from the guiding member and the portion of the stem can be inserted between the guiding member and the pressing member. In the closed position, the pressing member is generally arc-shaped and substantially parallel to the guiding member, and the centre of the pressing member is spaced away from the guiding member at a predetermined distance which corresponds substantially to the range of thickness of the stem in order to secure therein the portion of the stem after it has been inserted therein in the open position. Once the portion of the stem is secured in the frame, it has a predetermined curvature following the inside concave surface of the guiding member.

Abstract: A process of producing an aluminum alloy sheet article of high yield strength and ductility suitable, in particular, for use in manufacturing automotive panels. The process comprises casting a non heat-treatable aluminum alloy to form a cast slab, and subjecting said cast slab to a series of rolling steps to produce a sheet article of final gauge, preferably followed by annealing to cause recrystallization. The rolling steps involve hot and warm rolling the slab to form an intermediate sheet article of intermediate gauge, cooling the intermediate sheet article, and then warm and cold rolling the cooled intermediate sheet to final gauge at a temperature in the range of ambient temperature to 340 ~C to form said sheet article. The series of rolling steps is carried out continuously without intermediate coiling or full annealing of the intermediate sheet article. The invention also relates to the alloy sheet article produced by the process.
