Abstract
The utility model relates to an intracavity support for repairing artery blood vessels, which belongs to a medical application device which can be implanted into the blood vessels. The support is mainly composed of ring network units and axial connection bodies, wherein, the ring network units are axially arranged, each ring network unit is respectively fixed with the axial connection bodies to form a tubular body, and the outer surface of the tubular body is provided with film. The utility model has the advantages of reasonable structure and strong compliance.
Description
This utility model relates to a kind of being mainly used in and repairs arterial vascular intracavity stent, belongs to the medical device in the implantable vessel.
At present, in the treatment of arterial disease, especially for diseases such as hemangioma, interlayer tumors, lumen of artery inner support introductory technique commonly used is treated, and is about to the lumen of artery inner support and sends into the arterial disease position, rebuilds arterial wall in lumen of artery, recovers the tremulous pulse normal blood flow.Though and existing lumen of artery inner support also can be finished this function, but existing support all is cylindrical, and all there are bending in various degree in tremulous pulse or diseased region, this cylindrical stent puts into tube chamber because unbalance stress, distortion, distortion can appear, can cause the support displacement, even the damage tube wall.
The purpose of this utility model is a kind of lumen of artery inner support of design, and it is rational in infrastructure, moves towards to change with blood vessel to be consistent, and avoids support in endovascular distortion.
The designed lumen of artery inner support of this utility model mainly is made of looped network unit and axial connector, looped network unit axially-aligned, each looped network unit is fixed with connector respectively, form tubular body, the appearance of tubular body is covered with film, film and tubular body are consolidated, and the end of tubular body is ups and downs non-planar abnormity end or arc abnormity end.
The looped network unit of the lumen of artery inner support that this utility model is designed is " Z " font, waveform or zigzag closed circle.
The central axis of the lumen of artery inner support that this utility model is designed is straight line or curve.
Connector in the designed lumen of artery inner support of this utility model is at least one axial raw silk rings or crooked silk.
The tubular body one end abnormity or the two ends abnormity of the lumen of artery inner support that this utility model is designed.
The height of the abnormity end of the lumen of artery inner support that this utility model is designed is looped network element diameter or maximum gauge 0.1～1.5 times.
That the appearance of the tubular body of the lumen of artery inner support that this utility model is designed can be is cylindrical, conical, biconial, toroidal.
The designed lumen of artery inner support of this utility model is when using, identical with the application of existing lumen of artery inner support, but because its each looped network unit is connected separately with raw silk rings respectively, therefore it can change according to the alteration of form of lesion tremulous pulse, reduce the stress torsional deformation, support and arterial wall are fitted tightly.By the support largely bending of silk as connector, compliance is strong, and this is that existing latticed cylindrical stent can not be accomplished.
The advantage of the lumen of artery inner support that this utility model is designed is:
1. rational in infrastructure, applied widely.Can be used for straight tube chamber, crooked tube chamber, sidewall and have in the ramose tube chamber, under the situation that does not influence the blood vessel operate as normal, repaired, treat;
2. compliance is strong, and support can change with the tube wall bending change, attaches more closely with tube wall, plays sealing arterial wall rent and strengthens the effect of arterial wall, has avoided support force uneven and cause displacement or damage arterial wall.
The designed lumen of artery inner support of this utility model is mainly used in arterial vascular reparation.
Fig. 1 is the structural representation of the designed lumen of artery inner support of this utility model.
Fig. 2 is the structural representation of the designed another kind of lumen of artery inner support of this utility model.
Fig. 3 is the structural representation of another designed lumen of artery inner support of this utility model.
In conjunction with specific embodiments the structure and the embodiment of the designed lumen of artery inner support of this utility model is described further with reference to the accompanying drawings below.
Embodiment 1
Lumen of artery inner support as shown in Figure 1, by " Z " font looped network unit 1 and form by a formed connector 2 of the raw silk rings identical with the looped network material, " Z " font looped network unit arranged in co-axial alignment, each looped network unit 1 homonymy and connector 2 are fixed as one, its appearance is covered with film 3, and film 3 links together with looped network unit 1.One end of this support is an abnormity, and port one side has recess 4.The height H of abnormity end is 0.5 times of looped network unit 1 diameter D.After this support is positioned in the ductus arteriosus wall, it can be with the tube wall bending, and can be crooked largely, but do not produce torsional deformation, the abnormity of port especially not only can be largely with being repaired the tube wall bending, can also keep the operate as normal of the arm that is connected with tube wall, one side of the port band recess 4 of support is aimed at the arm position, make the support wall can not hinder the communication of arm and arterial, adjuvant treatment effect is good.
Lumen of artery inner support as shown in Figure 2, its structure is similar substantially to embodiment 1, different is that looped network unit 1 is the waveform closed-loop, looped network unit 1 order axially-aligned, be fixed as one with connector 2, connector 2 is three symmetric and the different raw silk rings of looped network unit 1 material, and film 3 is fixed in 1 periphery, looped network unit by medical line.The port at the two ends of this support is ups and downs abnormity end, and the height H of abnormity end and H ' are respectively 1.5 and 1.2 times of looped network unit 1 diameter D.This kind support has and embodiment 1 identical functions and advantage, is particularly suitable for being repaired the equal bending in two ends of tube wall or the arteries that two ends all have arm.
Lumen of artery inner support as shown in Figure 3, its structure is similar substantially to embodiment 1, different is that connector 2 is the curved silks of four symmetric arcs identical with looped network unit 1 material, the diameter of each looped network unit 1 is inequality, looped network unit 1 is according to the ascending order axially-aligned of diameter, be fixed as one with connector 2, film 3 is fixed in 1 periphery, looped network unit by medical line, forms the tapered support of wall of central axis bending.The port of one end of this support is the abnormity end of circular arc, and the height H of abnormity end is 0.1 times of looped network unit 1 maximum dimension D.This kind support has and embodiment 1 identical functions and advantage, is more suitable for having than big and an end in the degree of crook that is repaired tube wall the arteries of arm.
Claims (7)
1. lumen of artery inner support, it is characterized in that: mainly constitute by looped network unit and axial connector, looped network unit axially-aligned, each looped network unit is fixed with connector respectively, form tubular body, the appearance of tubular body is covered with film, and film and tubular body are consolidated, and the end of tubular body is ups and downs non-planar abnormity end or arc abnormity end.
