摘要: Un implant chirurgical possédant la forme d'une flèche comprend un corps (1) dont la première extrémité est constituée comme une hampe (2) et dont l'autre extrémité est constituée comme une tête (3) avec des dispositifs d'arrêt (5) conçus pour arrêter l'implant dans une position selon son utilisation, notamment dans la direction opposée à la direction d'introduction. La hampe (2) fait saillie par rapport à la surface extérieure du corps (1). L'implant est fabriqué dans un polymère ou un composé polymérique qui est substantiellement absorbable par les tissus et qui contient des éléments de renforcement ou des éléments similaires également constitués d'un polymère ou d'un composé polymère. La hampe est substantiellement constituée d'une ailette ou d'un élément similaire (4) s'étendant dans la direction longitudinale du corps et qui est reliée au corps (1) par un bord (4a). Les dispositifs d'arrêt (5) sont de préférence formés, au moins partiellement, en usinant le matériau, c'est-à-dire en découpant le matériau du corps (1) dans une direction sensiblement parallèle et/ou diagonale par rapport au corps (1).

摘要: Supporting structure (1) for preventing the movements of powder material (2) which will be applied as bone graft (bone graft powder) which supporting structure (1) will be located to contact with bone tissue and which supporting structure (1) is manufactured of at least partially resorbable polymer, copolymer or polymer mixture and is of its form chute-like, box-like, a flat tube or bag and contains such open porosity, which allows the surrounding tissues to grow through the supporting structure (1) but which prevents the migration of the bone graft powder (2) through the pores outside the supporting structure (1). The part of the supporting structure (1) which will be located against bone surface contains at least one orifice, whose size is bigger than the size of pores of the supporting structure (1) and bigger than the size of the bone graft powder (2) particles, which orifice makes possible the growth of the bone tissue into the inside of the supporting structure (1).

摘要: Matériaux chirurgicaux absorbables autorenforcés et/ou implants et/ou parties et/ou éléments d'implants, qui peuvent être implantés dans des tissus vivants ou sur la surface de ces tissus pour, par exemple, réparer des tissus endommagés, pour joindres des tissus ou des parties de tissus entre elles, pour accroître des tissus ou parties de tissus, pour séparer des tissus ou parties de tissus les uns des autres ou de leur milieu environnant, et/ou pour insérer des matières entre des tissus ou parties de tissus et/ou les en extraire ou les y introduire. Les éléments de renforcement de ces matériaux autorenforcés et/ou implants ou parties et/ou éléments sont enroulés au moins en partie autour d'un axe qui pénètre dans l'implant. Ces implants présentent des propriétés de résistance supérieures et plus isotropes que ceux de l'état antérieur de l'art.

摘要: The invention relates to structures and/or devices which are in an intimate tissue contact or are installable at least partly to the inside of tissues and/or organs and/or body cavities (ducts), and which have some function (especially core layer II), such as the supporting and/or joining and/or replacing of tissues and/or organs or parts thereof, and/or the con veying of material and/or energy between various parts of the body and/or between the body and its environment. At least a part of the surfaces of the structures and/or devices in question comprises an organic and/or inorganic surface layer (I) containing antimicrobial or other chemotherapeutic substance or combination of substances being releasable from the sur face layer in tissue conditions and preventing the growth of micro-organisms or corresponding organisms or killing them, thus preventing the propagation of micro-organisms and corresponding organisms, the start of infection, the propagation of infection, or suppressing infection, in the tissues and/or on the surface layer (I) of said structure and/or device.

摘要: This invention describes a multilayer plate for fixation of bone fractures, osteotomies, arthrodeses or corresponding or for fixation of a ligament, tendon or connective tissue on the bone, which multilayer plate is fixed on the bone at least with one fixing device, like screw, rod, clamp or corresponding and the said multilayer plate comprises at least two essentially superimposed plates, which have been manufactured of polymer, copolymer, polymer mixture or polymer composite and which multilayer plate be bent in operation room by hand or by means of suitable bending instrument to follow the form of the bone surface. The single plates of the multilayer plate can glide in relation to each other in beginning of their surgical installation but they are locked to their place during the fixation process. Accordingly the multilayer plate creates an exact and strong fixation of a bone fracture without the need to heat the plate system for bending it.

摘要: L'invention concerne des films polymères absorbables et/solubles non poreux ou poreux que l'on a renforcé avec des éléments structurels orientés, au moins partiellement absorbables et/ou solubles comme des chaînes moléculaires orientées, des lamelles, des filaments ou des fibres cristallins, ou des structures construites en fibres. On applique les films de cette invention soit pour assembler des tissus ou leurs parties les uns aux autres soit pour les séparer les uns des autres de manière notamment à protéger la croissance régulée de parodonte ligamenteux et/ou de cémentation.

摘要: Une structure de support (1), destinée à empêcher les déplacements d'un matériau pulvérulent (2) qu'on applique à la façon d'une greffe osseuse (poudre de greffe osseuse), est disposée de façon à entrer en contact avec les tissus osseux et est fabriquée à partir d'un polymère, d'un copolymère ou d'un mélange polymère au moins partiellement résorbable. Ladite structure est en forme de goulotte, de boîte, de tube plat ou de sac et comporte une porosité ouverte qui permet aux tissus environnants de croître à travers elle (1) mais qui empêche la migration de la poudre de greffe osseuse (2) à travers les pores hors de la structure de support (1). La partie de la structure de support (1) qui est disposée contre la surface osseuse est pourvue d'au moins un orifice, dont la dimension est supérieure à celle des pores de la structure de support (1) et à celle des particules de la poudre de greffe osseuse (2), ledit orifice permettant la croissance du tissu osseux à l'intérieur de la structure de support (1).
