Abstract
Description
L'invention se rapporte à une structure d'endoprothèse pour cavité anatomique, en particulier pour vaisseau sanguin. The invention relates to a stent structure for an anatomical cavity, in particular for a blood vessel.
Une application privilégiée consiste en un stent (appelé également dans certains cas étai ou élargisseur de paroi anatomique) ou en une armature tubulaire de prothèse destinée au traitement d'un anévrisme, une telle prothèse comprenant non seulement une armature, mais également un manchon tubulaire souple lié à cette armature pour canaliser le sang, comme par exemple dans US-A-5 456 713. A preferred application consists of a stent (also called in some cases forestay or anatomical wall enlarger) or in a tubular framework of prosthesis intended for the treatment of an aneurysm, such a prosthesis comprising not only a framework, but also a flexible tubular sleeve linked to this armature to channel the blood, as for example in US-A-5,456,713.
En l'espèce, il s'agit d'une endoprothèse susceptible d'occuper un premier état radialement resserré pour son introduction dans le corps du patient, jusqu'à l'intérieur du conduit considéré, en particulier par la méthode maintenant classique dite "de SELDINGER", (voir également à cet égard, si nécessaire, la description de US-A-5 456 713), ou bien un second état radialement déployé dans le conduit afin d'y rétablir une circulation appropriée du sang, en particulier dans le cadre d'un traitement d'anévrisme ou de sténose. In this case, it is a stent capable of occupying a first radially constricted state for its introduction into the patient's body, up to the interior of the duct considered, in particular by the now conventional method known as " SELDINGER ", (see also in this regard, if necessary, the description of US-A-5,456,713), or else a second state radially deployed in the duct in order to re-establish an appropriate circulation of the blood, in particular in as part of an aneurysm or stenosis treatment.
Pour son déploiement radial à partir de son premier état, la présente prothèse, qui se présente comme une structure tubulaire (tube unique ou éventuellement bifurqué en "Y") est prévue pour se déployer radialement, à partir de son premier état, uniquement sous l'effet d'une force radiale à son axe, a priori exercée à l'intérieur de l'endoprothèse, par exemple au moyen d'un ballon gonflable. For its radial deployment from its first state, the present prosthesis, which is presented as a tubular structure (single tube or possibly bifurcated in "Y") is intended to deploy radially, from its first state, only under the effect of a radial force at its axis, a priori exerted inside the stent, for example by means of an inflatable balloon.
L'endoprothèse n'est donc pas autoexpansible radialement. The stent is therefore not radially self-expanding.
On connaît aujourd'hui de nombreuses formes différentes de dessins de structures pour de telles endoprothèses (voir par exemple US-A-4 733 665). Many different forms of structural drawings are known today for such stents (see for example US-A-4,733,665).
Les dessins actuels ne satisfont pas à toutes les exigences requises, en particulier de flexibilité, adaption aux formes parfois tortueuses des vaisseaux, résistance axiale à l'écrasement, régularité lors de l'expansion radiale, facilité de fabrication, régularité du dessin sur l'ensemble de la surface de la structure. The current designs do not meet all the required requirements, in particular flexibility, adaptation to the sometimes tortuous shapes of the vessels, axial resistance to crushing, regularity during radial expansion, ease of manufacture, regularity of the drawing on the whole surface of the structure.
L'invention a pour objet de résoudre l'essentiel au moins de ces problèmes. The object of the invention is to solve at least the essential of these problems.
Pour cela, il est ici proposé une structure de prothèse monobloc tubulaire présentant dans son état radialement resserré (si l'on décrit cette structure en la supposant développée à plat) une succession de lignes ondulées s'étendant globalement parallèlement à un axe général (axe du tube), chaque ligne étant constituée à partir d'une forme seulement "en oméga" toute en courbes arrondies comportant deux branches cintrées définissant un col, ces branches étant réunies entre elles par une tête renflée très aplatie, cette forme "en oméga" se reproduisant régulièrement le long de l'axe de ladite ligne, les "omégas" aplatis successifs étant réunis par des tronçons axiaux, et les lignes ainsi formées étant disposées en phase et situées à distance, les unes des autres, deux lignes successives étant réunies entre elles par une série de tronçons coudés identiquement orientés, chaque tronçon coudé étant raccordé d'un côté à l'endroit du col de l'une des branches cintrées d'un des "omégas aplatis" et, de l'autre, sensiblement au milieu de la tête aplatie de "l'oméga" en regard de la ligne suivante, le tronçon considéré présentant une convexité orientée vers l'autre branche du col. For this, it is proposed here a tubular monoblock prosthesis structure having in its radially tightened state (if this structure is described assuming it developed flat) a succession of wavy lines extending generally parallel to a general axis (axis of the tube), each line being formed from a shape only "in omega" all in rounded curves comprising two curved branches defining a neck, these branches being joined together by a very flat swollen head, this shape "in omega" reproducing regularly along the axis of the said line, the successive flattened "omegas" being joined by axial sections, and the lines thus formed being arranged in phase and located at a distance, from each other, two successive lines being joined between them by a series of identically oriented bent sections, each bent section being connected on one side at the neck of the one of the curved branches of one of the "flattened omegas" and, on the other, substantially in the middle of the flattened head of the "omega" opposite the next line, the section considered having a convexity oriented towards the other branch of the neck.
Une telle structure à forme répétitive, avec un dessin régulier définissant une succession de cellules identiques sur toute la surface de la structure et qui, une fois repliée sur elle-même, définit un tube monobloc, est représentée en vue générale sur la figure 1 et, en vue agrandie et suivant un détail local, sur la figure 2. Such a repetitive shape structure, with a regular pattern defining a succession of identical cells over the entire surface of the structure and which, once folded back on itself, defines a one-piece tube, is shown in general view in FIG. 1 and , in enlarged view and according to a local detail, in FIG. 2.
Sur la figure 1, la structure 1 d'endoprothèse représentée est un stent figuré dans son état radialement resserré, prêt à être implanté pour doubler localement l'intérieur de la paroi d'un conduit anatomique, tel en particulier qu'un vaisseau sanguin dans le cas d'une sténose. In FIG. 1, the endoprosthesis structure 1 shown is a stent shown in its radially tightened state, ready to be implanted to locally line the inside of the wall of an anatomical conduit, such as in particular a blood vessel in the case of a stenosis.
Le stent 1 pourrait être lui-même doublé (intérieurement ou extérieurement) et sur une partie au moins de sa longueur par un fin manchon souple (non représenté) tel qu'on en connaît déjà dans le cadre du traitement d'un anévrisme vasculaire (voir par exemple
US-A-5 456 713).The stent 1 could itself be doubled (internally or externally) and over at least part of its length by a thin flexible sleeve (not shown) as is already known in the context of the treatment of a vascular aneurysm ( see for example
US-A-5,456,713).
La structure 1 est une structure d'une seule pièce définie par un dessin métallique susceptible d'être obtenu par érosion chimique et/ou découpe laser, à partir d'une plaque que l'on courbe ensuite sur elle-même pour obtenir un tube, ou à partir directement d'un tube à surface périphérique pleine. Structure 1 is a one-piece structure defined by a metallic design capable of being obtained by chemical erosion and / or laser cutting, from a plate which is then curved on itself to obtain a tube , or directly from a tube with a full peripheral surface.
Le métal utilisé peut être de l'acier inoxydable (INOX 316L), voire d'autres métaux utilisables dans les conduits anatomiques, tels que par exemple celui connu sous la dénomination "Nitinol". The metal used can be stainless steel (INOX 316L), or even other metals which can be used in anatomical conduits, such as for example that known under the name "Nitinol".
La structure est tubulaire, de section cylindrique, d'axe longitudinal la, et est susceptible d'occuper un premier état radialement resserré pour son introduction dans le conduit anatomique retenu, ou un second état radialement déployé atteint sous l'effet d'une force de déploiement radiale susceptible d'être obtenue par l'intermédiaire d'un cathéter terminé par un ballon gonflable autour duquel le stent 1 est disposé, pour son implantation, comme cela est décrit notamment dans US-A-4 733 665. The structure is tubular, of cylindrical section, of longitudinal axis la, and is capable of occupying a first radially tightened state for its introduction into the retained anatomical conduit, or a second radially deployed state reached under the effect of a force radial deployment capable of being obtained by means of a catheter terminated by an inflatable balloon around which the stent 1 is arranged, for its implantation, as described in particular in US-A-4,733,665.
Pour l'introduction corporelle du dispositif d'implantation du stent vers l'extrémité distale duquel ledit stent a été préchargé (autour du ballon gonflable si un tel moyen d'expansion radiale est utilisé), on peut en particulier prévoir de suivre la méthode dite "de
SELDINGER".For the bodily introduction of the stent implantation device towards the distal end from which said stent has been preloaded (around the inflatable balloon if such a radial expansion means is used), it is in particular possible to plan to follow the so-called method "of
SELDINGER ".
On va maintenant décrire plus précisément la structure de la paroi tubulaire 3 qui définit le stent 1, en l'espèce dans son état radialement ressérré. We will now describe more precisely the structure of the tubular wall 3 which defines the stent 1, in this case in its radially tightened state.
Considérons tout d'abord que l'on place le stent avec son axe la horizontal et qu'il s'agit d'une structure déployée à plat, comme sur la figure 1 et comme on le voit plus en détail sur la figure 2. First consider that we place the stent with its axis horizontal and that it is a structure deployed flat, as in Figure 1 and as seen in more detail in Figure 2.
La structure peut-être décrite comme présentant un dessin définissant une succession de méandres s'étendant globalement suivant une série de directions telles que 5a, 5b, parallèles entre elles et à l'axe général la. The structure can be described as having a drawing defining a succession of meanders extending generally along a series of directions such as 5a, 5b, parallel to each other and to the general axis la.
Suivant ces lignes, les méandres dessinent une succession de formes en "omega", telles que 7 et 9, à courbes arrondies. Following these lines, the meanders draw a succession of "omega" shapes, such as 7 and 9, with rounded curves.
Chaque oméga, tel que 7, présente deux branches cintrées 7a, 7b définissant respectivement un "S" et un "S inversé" (image du premier dans un miroir), les deux branches définissant entre elles un col 11. Each omega, such as 7, has two curved branches 7a, 7b respectively defining an "S" and an "inverted S" (image of the first in a mirror), the two branches defining between them a neck 11.
Ces branches sont en outre réunies entre elles, au sommet des "S", par un tête renflée 13 très aplatie (en ltespèce d'ailleurs tellement aplatie que tout son tronçon central est rectiligne et parallèle à l'axe la). These branches are also joined together, at the top of the "S", by a very flattened bulging head 13 (in fact, so flattened that its entire central section is rectilinear and parallel to the axis la).
Un tronçon linéaire axial 15 (de même longueur que le tronçon de tête aplatie 13) relie, sur une même ligne, deux "omégas aplatis" successifs. Ainsi, comme on peut le voir sur la figure 1, cette forme "en oméga aplati" se reproduit périodiquement, avec une périodicité constante, le long de l'axe 5a, 5b,... qui lui correspond, de telle sorte qu'une fois une ligne dessinée, on voit apparaître une succession d'omégas se développant alternativement d'un côté puis de l'autre de l'axe 5a, 5b,... considéré. An axial linear section 15 (the same length as the flattened head section 13) connects, on the same line, two successive "flattened omegas". Thus, as can be seen in FIG. 1, this "flattened omega" shape reproduces periodically, with a constant periodicity, along the axis 5a, 5b, ... which corresponds to it, so that once a line has been drawn, we see a succession of omegas appear, developing alternately on one side then on the other of the axis 5a, 5b, ... considered.
Par ailleurs, d'une ligne à l'autre, les omégas sont disposés en phase et à distance les uns des autres, c'est-à-dire donc de manière séparée. Furthermore, from one line to another, the omegas are arranged in phase and at a distance from each other, that is to say therefore separately.
Deux lignes successives, telles que le long de 5b, 5c, sont toutefois réunies entre elles par une série de tronçons coudés étagés axialement, tel que le tronçon 17 pour la liaison entre la base de l'oméga 7 et le tronçon de sommet axial aplati 19 de l'oméga 9. Two successive lines, such as along 5b, 5c, are however joined together by a series of bent sections axially stepped, such as the section 17 for the connection between the base of the omega 7 and the flattened axial crown section. 19 of Omega 9.
Ce tronçon coudé 17, à l'image des autres tronçons identiques, est raccordé à une extrémité (en 21), à l'endroit du col 11 de la branche 7b de l'oméga 7 et, à l'extrémité opposée (en 23), au milieu de la branche 19 de la tête aplatie de l'oméga 9 situé en regard du précédent. This bent section 17, like the other identical sections, is connected at one end (at 21), at the location of the neck 11 of the branch 7b of the omega 7 and, at the opposite end (at 23 ), in the middle of branch 19 of the flattened head of omega 9 located opposite the previous one.
Le tronçon de raccordement 17, comme les autres tronçons, présente une convexité orientée vers l'autre branche du col sensiblement à l'endroit duquel il s'étend, à savoir la branche 7a du col 11 pour le tronçon 17. The connecting section 17, like the other sections, has a convexity oriented towards the other branch of the neck substantially at the point where it extends, namely the branch 7a of the neck 11 for the section 17.
A noter qu'au vu des figures 1 et 2, on remarquera qu'en l'espèce, tous les tronçons de raccordement ont une convexité tournée vers la gauche et se raccorde à la branche droite du col d'un oméga "supérieur" (oméga 7, par comparaison avec l'oméga 9). It should be noted that, in view of FIGS. 1 and 2, it will be noted that in this case, all the connecting sections have a convexity turned to the left and are connected to the right branch of the neck of an "upper" omega ( omega 7, compared to omega 9).
