Patent CA-2409662-A1 (CA)
Inventor: MOODY RALPH A III
IPC: D04H1/46
Filed: 2002-03-14
Abstract: L'invention porte sur un non tissé composite composé d'une bande de fibres synthétiques (10), telle qu'une longueur de fibres polymères, et d'une bande de fibres de cellulose (11), comprenant de préférence des fibres de pâte de bois. Avant l'intégration des bandes, les fibres synthétiques sont soumises à un hydro-entremêlement afin qu'une bande partiellement entremêlée soit formée, la bande de fibres cellulosiques étant ensuite juxtaposées sur cette dernière, en vue d'un nouvel hydro-entremêlement précédant l'intégration des bandes. Ce pré-entremêlement de la bande de fibres synthétiques a pour but de réduire au minimum l'énergie nécessaire à l'intégration de la bande de fibres synthétiques et de la bande de fibres cellulosiques, et permet de réduire les pertes de fibres cellulosiques pendant l'hydro-entremêlement et l'intégration desdites bandes.

On a développé une méthodologie permettant de produire des PHA à partir de voies de biosynthèse d'acides gras dans des producteurs de PHA bactériens non natifs et dans des végétaux utilisant une enzyme présentant l'activité catalytique de 3-hydroxyacyle-ACP thioestérase, une acyl-CoA synthétase présentant une spécificité de substrat pour des acides gras 3-hydroxy à chaîne de longueur moyenne, et une PHA synthase de chaîne de longueur moyenne. L'activité de l'acyl-CoA synthétase peut être produite soit par l'acyl-CoA synthétase endogène de l'organisme hôte, lorsqu'elle est suffisamment exprimée, ou l'activité de l'organisme hôte peut être suppléée par l'expression d'un gène d'acyl-CoA synthétase recombinant. De nouvelles stratégies sont décrites pour produire des PHA à partir de végétaux, dans les chloroplastes, le cytosol, et les peroxysomes de cultures de biomasse ainsi que dans les plastides, le cytosol, et les peroxysomes de cultures de graines oléagineuses.

Abstract: L'invention concerne une orthèse comprenant des supports à longueur réglable. Cette orthèse comprend des supports supérieurs et inférieurs reliés rotatifs par une charnière. Chaque support comprend un segment allongé traversé en partie par un sillon, et une attelle coulissante qui s'emboîte avec le sillon. Cette attelle peut avancer progressivement à l'intérieur du sillon dans le sens de la longueur de façon à régler la longueur du support. Des brides situées sur les bords du sillon empêchent l'attelle de se séparer latéralement de la partie fixe. Un bouton sollicité par ressort fait saillie depuis la surface supérieure du sillon. Ce bouton coopère avec l'un des plusieurs trous pratiqués dans l'attelle pour assurer un blocage positif permettant de retenir l'attelle dans l'une des plusieurs positions prédéterminées dans le sillon. L'attelle peut être complètement enlevée du sillon. Le fait de retirer l'attelle du sillon raccourcit l'orthèse. Des lanières coopèrent avec des fixations sur les supports et/ou les attelles pour fixer l'orthèse sur la jambe du patient.

Title: Use of occlusion device for the local delivery of biologically active dna therapeutic compounds for treating aneurysms and use thereof
Inventor: LECLERC GUY
IPC: A61F2/06
Filed: 2002-02-22
Abstract: The invention relates to a method for the sustained endovascular treatment of aneurysms, such as intracranial or for closing any body lumen, such as vascular lumen or other using an occlusion device for the local delivery of biologically active DNA therapeutic molecules. The invention also relates to a method for a rapid preparation of the artificial occlusion device to be coated shortly before or during the clinical procedure. A subsequent step in the method of treatment involves introducing at an aneurysm site or inside a vessel a slow-releasing, biologically active DNA molecule-leaching device. The device releases a biologically active DNA molecule at the aneurysm site for stimulating neointima formation and for increasing neointima thickness. The neointima formation fills the aneurysm and the biologically active DNA  molecule released in the aneurysm is absorbed by surrounding tissues of the aneurysm for providing long-term treatment of the aneurysm preventing recanalisation.
