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, and each looped network unit is fixed with connector respectively, forms tubular body, and the appearance of tubular body is covered with film, and film and tubular body are consolidated.
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.
Connector in the designed lumen of artery inner support of this utility model is an axial raw silk rings.
Gap between the adjacent ring net unit of the lumen of artery inner support that this utility model is designed can be 0～0.2 times of looped network element diameter.
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 of a raw silk rings as connector, gap between adjacent net ring element and raw silk rings noncontact point can change, can change with the difference of tube wall bending, and can be crooked largely, 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, also can be used for the reparation of other tube chamber in the bodies such as trachea, esophagus.
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.
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.Can produce gap T between the opposite side that adjacent ring net unit 1 and connector 2 are corresponding in this kind lumen of artery inner support, gap T can change in 0～0.2D scope, and wherein D is the diameter of looped network unit 1.After this support was positioned in the ductus arteriosus wall, it can be with the tube wall bending, and can be crooked largely, but does not produce torsional deformation, and 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, connector 2 is a raw silk rings different with the looped network material, film 3 is the cloth film, looped network unit 1 order axially-aligned and connector 2 are fixed as one, and film 3 is fixed in 1 periphery, looped network unit by medical line, forms an artificial tube chamber.This kind support has and embodiment identical functions and advantage.
Claims (4)
1. lumen of artery inner support is characterized in that: mainly constitutes by looped network unit and axial connector, and looped network unit axially-aligned, each looped network unit is fixed with connector respectively, forms tubular body, and the appearance of tubular body is covered with film, and film and tubular body are consolidated.
2. lumen of artery inner support according to claim 1, its feature also is: the looped network unit is " Z " font, waveform or zigzag closed circle.
3. lumen of artery inner support according to claim 1, its feature also is: connector is an axial raw silk rings.
4. lumen of artery inner support according to claim 1, its feature also is: the gap between the adjacent ring net unit can be 0～0.2 times of looped network element diameter.
