Definitions
- the invention relates to the technical sector of stents also known as STENTS.
- This type of endoprosthesis consists of tubular organs of small section forming an openwork metallic structure and designed to be implanted with the aim of strengthening the walls of the arteries and restoring their permeability, i.e. restoring arterial lumen to allow free circulation of blood.
- these stents can be used in angioplasty after dilation of the artery thanks to the introduction of a balloon catheter to support the arterial walls, glue the dissections and restore the lumens in weakened areas partially occluded and collapsed or on the contrary abnormally dilated.
- the aim is to restore the lumen of any physiological duct such as vein, artery, bile duct or urinary tract, tracheobronchial tree, digestive system and genitourinary system ...
- stents are made of stainless steel and put in place by expansion of a balloon, or they are made of super-elastic, self-expanding alloy, or even of shape memory alloy.
- the stent is placed coaxially around the balloon of a catheter by light crimping.
- the catheter is introduced into the artery and brought to the implantation site by means of a flexible metal guide, under radiographic control of the operator.
- the balloon is gradually inflated in order to dilate the artery and at the same time deploy the prosthetic structure to the desired diameter.
- the balloon is then deflated and the catheter removed with the metal guide, leaving the stent open and in place.
- a self-expanding stent In a second case of a self-expanding stent, the latter is placed coaxially around the end of a delivery catheter and held in this position by an external sheath. When the catheter is in place, a gradual withdrawal of the external sheath ensures the opening of the stent which then returns to its initial diameter.
- a stent made of a thermal memory alloy the latter is modeled in a given configuration when cold which allows its implantation. After being heated to its transition temperature, the structure loses its malleability and returns to its initial configuration. It is this property that is used for fitting the self-expanding stent with shape memory. From this basic general design, there are essentially two main categories of endoprosthesis obtained from two different manufacturing techniques.
- the endoprosthesis must be able to be placed without difficulty in sinuous and small diameter ducts such as the coronary arteries.
- the radial force to guarantee the opening in calcified arteries and to allow the endoprosthesis to remain open after the installation, it must be sufficient to support the walls of the conduit, but limited all the same so as not to damage the tissues of the walls at the time of installation and / or after installation.
- the length of the endoprosthesis should not vary at the time of its implantation, so, on the one hand, to avoid traumatizing the walls at the implantation site and, on the other hand, to ensure sufficient coverage in length of the site to be treated. Too much shrinkage requiring the operator either to implant another stent to cover the entire area to be treated, or to use a stent of a much greater length.
- the final diameter is a function of the diameter of the balloon and the inflation pressure.
- the endoprosthesis must have the smallest possible insertion diameter in order to control the trauma during its introduction and to facilitate its placement at the site to be treated.
- the metal / artery ratio must be as low as possible, the stent should not generate turbulent flow likely to cause thrombosis (in the case of arterial or venous stents for example) and should not generate a proliferative tissue reaction likely to cause restenosis.
- Endovascular prostheses as defined according to the state of the art do not have all of these characteristics combined.
- articulated tubular stents have been developed.
- the metal / artery ratio of mesh tubular stents is less favorable (10 to 25%) and can be inconvenient at the bifurcations for the passage of blood through the colateral arteries.
- shrinkage is important (up to 40
- the object of the invention is to remedy these drawbacks in a simple, safe, efficient and rational manner.
- the problem which the invention proposes to solve is to produce a stent of the tubular type which is capable of offering all the desired characteristics in terms of flexibility, radial force, withdrawal, elastic recoil, profile, all by combining the advantages of other tubular mesh prostheses and the advantages of endoprostheses made from wires.
- a stent with a mesh structure composed of a plurality of deformable patterns remarkable in that the structure is made up has been designed and developed.
- a series of parallel straight lines regularly distributed over a circumference - the parallel straight lines are connected by symmetrical broken lines, all of said broken lines having a geometric shape and dimensions determined to ensure the deployment of the structure d '' a symmetrical and regular manner with an elastic recoil of less than 1%
- - each straight line has, between the broken connecting lines and in a symmetrical manner, broken lines having a geometric shape and dimensions determined to give flexibility to the structure while prohibiting a variation in its length.
- the endoprostheses being able to be used as well in arteries of small distal caliber, sinuous and or calcified as in arteries of larger caliber: venous grafts, arteries peripheral, aorta or other ducts.
- the mesh of the structure as defined allows deployment without any shrinkage and an elastic recoil limited to 1% for a diameter of approximately 3 mm. It is also possible to obtain a reduced profile necessary for the insertion of the stent but also a favorable metal / artery ratio of less than 20%.
- the patterns delimit two end zones and at least one intermediate zone, each zone consisting of broken lines.
- the broken end connection lines are formed by two rectilinear segments delimiting a symmetrical V, the apex of which is directed inside the structure.
- the broken intermediate connecting lines consist of three rectilinear segments delimiting two identical and opposite V's joined by a common segment, the other two segments of each of the two opposite V's, being connected to the corresponding parallel straight lines, by rectilinear segments of reduced length oriented perpendicular to said straight lines.
- the broken lines of each of the straight lines are constituted by three rectilinear segments delimiting two identical and opposite Vs joined by a common segment and symmetrically by the other two segments to each of said straight lines.
- the broken lines of each of the straight lines are arranged at equal distance from each of the broken connecting lines, the four parallel straight lines being regularly angularly offset around a circumference.
- FIG. 1 on a large scale, is a perspective view of the stent
- FIG. 2 is a schematic view showing the mesh principle of the tabular structure of the stent
- FIG. 3 on a large scale, is a flat view of the endoprosthesis before it is deployed
- Figure 4 is a flat view of the endoprosthesis shown in Figure 3 after deployment.
- Figures 5 and 6 are partial views, on a very large scale, showing examples of details of embodiment of the broken lines.
- the flexible and tabular stent has a mesh structure composed of a plurality of deformable patterns.
- the mesh structure delimits end zones (A) and (C) and at least one intermediate zone (B).
- end zones A and (C) and at least one intermediate zone (B).
- the end zones are recommended since they are shaped, as will be indicated in the following description, to avoid any risk of injury or tearing during the introduction and / or removal of the stent.
- the structure consists of a series of parallel straight lines (1) regularly distributed over a circumference.
- the structure has four parallel straight lines regularly offset angularly around the circumference.
- the diameter of the structure is substantially equal to 1.6 mm and can range up to 4 - 4.5 mm.
- the length of the structure can be from 8 to 45 mm approximately.
- the parallel straight lines (1) are connected at their free end by symmetrical broken lines (2).
- the straight lines (1) are also connected, preferably at regular intervals, at the intermediate zones (B) by broken lines (3).
- the geometric shapes and dimensions of the broken lines (2 and 3) are determined to ensure the deployment of the structure, in a symmetrical and regular manner, with an elastic recoil of less than 1%.
- the broken end lines (2) are constituted by two rectilinear segments (2a - 2b) delimiting a symmetrical V whose apex is directed inside the structare.
- V are connected to the ends of the corresponding parallel straight lines (1) and to the other V-shaped segments, by rectilinear segments (2c) of reduced length and oriented substantially perpendicular to said straight lines (1).
- the broken lines (3) of intermediate connection consist of three rectilinear segments (3a), (3b) and (3c). These three segments delimit two
- each straight line (1) has, between the broken connecting lines (2 and 3), and between the different intermediate broken lines (3), in a symmetrical manner, broken lines (4) having a geometric shape and dimensions determined to give flexibility to the structare while prohibiting a variation in its length.
- the broken line (4) being constituted by three rectilinear segments (4a - 4b - 4c) delimiting identical and opposite 2V joined by the common segment (4b) and symmetrically by the two other segments (4a and
- the different broken lines (4) are arranged at equal distance from each of the broken connecting lines (2 and / or 3).
- the stent can be produced from a tube of diameter and thickness chosen according to the diameter to be reached after deployment. The choice of the number of central patterns over a given length will optimize the final flexibility and the total and symmetrical deployment of the endoprosthesis at a given diameter.
- the stent can be made of any implantable material capable of being cut and / or shaped by any suitable means. It is preferably made of 316 LVM stainless steel with elastic characteristics suitable for this use. It can also be coated with any implantable material in order to improve its hemocompati bilitc or allow the diffusion of medicinal substances active against cell proliferation responsible for the phenomena of restenosis. Finally, it can be made of a biodegradable material for indications of temporary stents.
- the mesh structure of the stent combines the advantages obtained in the case of tubular mesh endoprostheses and stents made from wires.
- endoprosthesis in small distal, sinuous or calcified catheters, as well as in larger arteries such as venous grafts, peripheral arteries, aortas, or in any other conduit.
