Abstract
An aortic intracavity implant, which is provided with an anchoring zone at the near-end to reliably fix the implant and prevent the inner leakage, is provided. A membrane braid is used for replacing partial overlay film of the aortic intracavity implant, in the operation, a central region of the membrane braid is opposite to a left subclavian artery opening, under the pressure of aortic blood pressure the central region is inserted into the left subclavian artery, the top is sparse under the pressure effect to form an opening, thus the blood supply of the left subclavian artery can be maintained. A main body structure of the membrane braid is elliptic, and is divided into a central region and a peripheral region, no absolute boundary line is arranged between the central region and the peripheral region, the braid from the peripheral to the central region is gradually sparse. No leakage is provided at the peripheral region, and the central region is provided with an opening in the opening process. The membrane braid has no supporting effect on the aortic intracavity implant, and has the main effects: (1) guaranteeing the blood supply of main branch blood vessel after the implant isopened, and adding the anchoring zone; and (2) having no leakage at the peripheral region of the membrane braid, thus preventing the inner leakage.
Description
Affiliated technical field
The present invention relates to a kind of branch unit of overlay film aorta intracavity implant, be primarily aimed at firm that the protection of aortic arch important branch blood vessel and aorta intracavity implant install.
Background technology
The present invention is directed to the treatment of Stanford Type B dissecting aneurysm and design.Stanford Type B dissecting aneurysm is meant the interlayer origin and is confined to descending aorta.Require the length of Type B interlayer near-end cervical region blood vessel should be in the endovascular graft, unobstructed with the firm and left subclavian artery of guaranteeing graft greater than 15mm.For the length of near-end cervical region blood vessel less than 15mm person, present main countermeasure is the reconstruction to left subclavian artery, comprise outside the chamber, two kinds of forms of intracavity: 1, reconstruction mode was meant before the aorta intracavity implant is placed and carries out various by-pass operations that method comprises right subclavian artery-left subclavian artery coronary artery bypass grafting and left common carotid artery-left subclavian artery coronary artery bypass grafting outside the chamber.2, the intracavity reconstruction mode comprises: (1) uses " gap " (scallop) sample graft reservation LSA.(2) part covers left subclavian artery and stent forming art.(3) original position windowing.(4) application is with ramose graft intracavity to rebuild LSA.Reconstruction has increased operation wound undoubtedly one time outside the chamber, and the technical difficulty of intracavity reconstruction at present is big, and length consuming time increases internal hemorrhage due to trauma etc.
Summary of the invention
For shutoff that overcomes aortic arch important branch blood vessel in the existing aorta intracavity implant use and the steadiness problem that the aorta intracavity implant is installed, the invention provides a kind of film sample fabric is installed on existing aorta intracavity implant, the blood that promptly guarantees the important branch blood vessel is for increasing the steadiness that graft is installed again.
The technical solution adopted for the present invention to solve the technical problems is: the part overlay film that replaces the aorta intracavity implant with a kind of film sample fabric, in operation technique, make the middle section of film sample fabric relative with the left subclavian artery opening, discharge graft, middle section is charged into left subclavian artery under the pressure of aortic blood pressure, its top becomes sparse under pressure, can keep the part blood of left subclavian artery to supply, after the support placement is finished, can carry out balloon expandable, supply with the blood that recovers left subclavian artery to the top.
Film sample fabric agent structure: be ellipse, be divided into middle section and neighboring area, both do not have absolute boundary line, and the braiding from the periphery to the middle section is sparse gradually shape.The neighboring area is water-tight, and middle section can form opening when strutting.Film sample fabric does not play a supportive role on the aorta intracavity implant, and it mainly acts on and is: (1) opens the blood confession that the back guarantees main branch vessel at graft, and the neighboring area of (2) film sample fabric is water-tight, thereby prevents the generation of internal hemorrhage due to trauma.
The invention has the beneficial effects as follows: 1, an arterypuncture point can be finished operation technique.2, do not need reconstruction mode outside the chamber, simplified the whole surgery therapeutic process.3, increased the anchorage zone of aortic prosthesis near-end, made the fixing more reliable of graft.4, overcome the influence of the variation of left subclavian artery to operation technique.5, prevent the generation of internal hemorrhage due to trauma.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a design sketch of the present invention.
Fig. 2 is the bright existing aorta intracavity implants of we to be installed.
Fig. 3 is a film sample fabric of the present invention.
1. existing aorta intracavity implants among the figure, 2. film sample fabric of the present invention, 11. rustless steel steel wire or alloy, 12. overlay film, 13. fixation hook, the cutting mouth on the 14. existing grafts, the top end opening of 21. film sample fabrics of the present invention, 22. the middle section of film sample fabric of the present invention, the neighboring area of 23. film sample fabrics of the present invention.
The specific embodiment
In Fig. 2, the overlay film of nearly fixation hook one end of existing aorta intracavity implant is by a cutting part.
In Fig. 1, fabric of the present invention is sutured in existing graft.In operation technique, make the middle section of film sample fabric of the present invention relative with the left subclavian artery opening, discharge graft, middle section is charged into left subclavian artery under the pressure of aortic blood pressure, its top becomes more sparse under pressure and forms opening, can keep the part or all of blood of left subclavian artery to supply, if the blood of left subclavian artery is for not recovering fully, can after the support placement is finished, can carry out balloon expandable, supply with the blood that recovers left subclavian artery fully to the top.
Claims (2)
1. aorta intracavity implant, on existing aorta intracavity implant, install " film sample fabric ", it is characterized in that: under the aortic blood pressure pressure, " film sample fabric " charges into left subclavian artery, middle section is sparse, has blood flow to pass through, and the neighboring area is tight, do not leak blood, play insulating effect and prevent the generation of internal hemorrhage due to trauma.
2. film sample fabric according to claim 1 is characterized in that: " film sample fabric " is divided into middle section and neighboring area for oval, and both do not have absolute boundary line, and the braiding from the periphery to the middle section is sparse gradually shape.The neighboring area is water-tight, and middle section can form opening when strutting." film sample fabric " do not play a supportive role on the aorta intracavity implant, and it mainly acts on and is: (1) opens the blood confession that the back guarantees main branch vessel at graft, and the neighboring area of (2) " film sample fabric " is water-tight, thereby prevents the generation of type internal hemorrhage due to trauma.
