Definitions
- the present invention relates to vascular prostheses intended for the treatment of aneurysms of the aorta by the endoluminal route.
- the endovascular prostheses currently proposed are intended in a first variant for repair provided by a straight prosthetic tube moored at its two ends by a stent.
- the repair is provided by an aortic bifurcation whose shape is close to the anatomical arrangement.
- Another document of the prior art published under the number EP508473 describes an endovascular prosthesis with bifurcation, formed by a mother branch and flexible daughter branches.
- the disadvantage of such a prosthesis constituting the closest state of the art is that surgical implantation involves the production of numerous models adapted to the diameters and lengths of the aorta and the iliacs.
- the object of the present invention is to remedy these drawbacks and to propose a prosthesis of which a single model allows adaptation to a wide range of vascular sections.
- Another goal is to offer a prosthesis whose surgical implantation is rapid, in order to reduce the time and cost of the intervention.
- the invention relates firstly to a bifurcated vascular prosthesis, formed by a tubular mother branch extended by two tubular daughter branches, characterized in that at least part of the mother branch comprises expandable frames.
- the parent branch is made of an expandable material, for example PTFE, reinforced by an expandable annular section.
- the entrance to the mother branch is formed by a bare tubular part. This exposed part allows better attachment of the prosthesis.
- the daughter branches are free and unarmed.
- the mother branch is expandable up to a diameter of about 28 mm, and in that the daughter branches have a conical shape whose end has a diameter of about 10 mm.
- the parent branch is extended by two expandable armed daughter branches up to a diameter of 10 mm, the expandable zones being offset longitudinally, and the daughter branches being of different lengths, so as to avoid overlapping of the armed zones .
- the daughter branches are each extended with expandable reinforced annular sections, the length of which can be adjusted as a function of the distal attachment to the iliacs.
- the invention will be better understood on reading the description which follows, referring to nonlimiting exemplary embodiments, where:
- FIG. 1 shows a sectional view of a first alternative embodiment of the invention
- FIG. 2 shows a sectional view of a second alternative embodiment of the invention
- FIG. 3 and 4 show sectional views of two alternative embodiments of extensions of the daughter branches of the prosthesis.
- Figure 1 shows a sectional view of a first embodiment of the invention.
- the prosthesis has a mother branch (1) and two daughter branches (2, 3).
- the mother branch is constituted by a tubular section, made of an expandable material, for example PTFE reinforced in its upper part by an expandable annular section.
- the mother branch has a middle part (1 ') in reinforced PTFE, extended towards the daughter branches (2, 3) by a part (1 ") in unarmed PTFE.
- the mother branch is expandable up to a diameter of about 28 mm
- the proximal end (4) of the mother branch is reinforced but stripped so as to improve the attachment to the aortic artery
- This mother branch forms bifurcated breeches extended by two free daughter branches (2, 3) Unarmoured, their section narrows slightly to give a conical shape, the end of which has a diameter of approximately 10 mm, improving distal attachment.
- the assembly thus formed is mounted on a catheter-guide balloon (6) allowing dilations. of the mother branch up to 28 mm depending on the type of balloon and its insufflation pressure, the daughter branches being rolled up on themselves.
- each branch (2, 3) of the bifurcation is then extended using rectilinear modules of known type, the length of which can be adjusted according to the attachment to each iliac (10, 10 ').
- rectilinear modules are advantageously expandable modules formed by expandable annular segments embedded in an envelope of an expandable material, for example PTFE.
- FIG. 2 represents a second embodiment.
- the mother branch (1) as well as the two daughter branches (2, 3) consist of expandable segments coated with an expandable material, for example PTFE.
- the two daughter branches (2, 3) have reinforced zones (21, 21 ') offset longitudinally so as to avoid overlaps which would otherwise result in an excess thickness preventing introduction into the vascular system.
- the daughter branch (3) is longer than the daughter branch (2); The junction part of the unarmed prosthesis can be predilated.
- the assembly is mounted on an expansion means making it possible to first expand the branch mother with a main balloon (6) up to 28 mm depending on the insufflation pressure, then the first daughter branch (2) up to 10 mm, using another balloon (25).
- the second daughter branch (3) is then expanded by a third balloon (26). It is also possible to use the same balloon to expand the mother branch first, then one of the daughter branches.
- the daughter branches (2, 3) are extended by rectilinear modules (11, 12) formed by annular segments of adjustable expandable lengths embedded in an envelope of expandable material, for example PTFE.
- FIG. 3 represents an exemplary embodiment of an extension of the daughter branch where the proximal end of a modular extension (27) has an unreinforced conical part (28) coming to connect with the distal end (29) of the branch mother.
- FIG. 4 shows an exemplary embodiment of an extension of the daughter branch where the proximal end of a modular extension (27) has an armed part (30) which is connected to the armed end (31) of the mother branch.
