Abstract
The utility model provides an arterial intracavity stent mainly used for repairing arterial vessels, and belongs to medical appliances which can be implanted into human bodies. The stent is mainly formed by connecting a peripheral stent and an intermediate stent through a stent connecting piece. The arterial intracavity stent is characterized in that the peripheral stent 1 and the intermediate stent 2 are connected through the stent connecting piece 3; and a film or fabric 4 covers the surface of the stent. The arterial intracavity stent provided by the utility model is suitable for treating arterial diseases at the distal side of branch artery, and is safe and reliable in use.
Description
Technical field
This utility model relates to a kind of being mainly used in and repairs arterial vascular lumen of artery inner support, belongs to the medical device of human implantable.
Background technology
At present, in the treatment of arterial disease, especially for pathological changes such as hemangioma, artery dissections; The normal interior interventional method of lumen of artery that adopts is treated; Be about to the lumen of artery inner support and send into the arterial disease position, in lumen of artery, rebuild arterial wall, recover normal blood flow through overlay film frame.Along with the application extension to the lumen of artery inner support, the pathological changes that begins to explore closing on the arterial branch position is treated.For example, in the overlay film frame treatment of carrying out the infrarenal abdominal aorta tumor,, I type internal hemorrhage due to trauma possibly occur and be not suitable for adopting at present general overlay film frame treatment, need change operative treatment into usually when the length of near-end tumor neck during less than 15mm.Simultaneously, near-end tumor neck length degree is less than the patient of 15mm later stage of pathological changes often, and patient age is bigger than normal, and risk increases in the operation.Therefore, the treatment for this type of patient remains one of clinical difficult problem.
Summary of the invention
This utility model technical problem to be solved provides a kind of lumen of artery inner support rational in infrastructure; Promptly pass through the peripheral overlay film frame of socket larger diameter on the basis of existing overlay film frame; In order to the gap between sealing middle bracket and the aneurysm wall; Be suitable for treating and be positioned at bifurcated artery distally and aneurysm neck length, avoid the generation of I type internal hemorrhage due to trauma, reduce the treatment risk less than the aneurysm of 15mm.
The lumen of artery inner support that this utility model designed mainly is formed by connecting through stand connection peripheral frame and middle bracket, and support and stand connection surface are covered with film or fabric, and film or fabric and support are consolidated.
In this utility model, peripheral frame is Z type structure or network, and peripheral frame diameter and middle bracket diameter ratio are between 1.1-2.0.
In this utility model, peripheral frame length and middle bracket length ratio between 0.1-0.9, the peripheral frame edge far from the distance at homonymy middle bracket edge between 10mm-60mm.
In this utility model, an end of stand connection is connected with middle bracket, and the other end is connected with peripheral frame, and the length of connector is between 1mm-20mm.
In this utility model, cover the film or the fabric of middle bracket and cover peripheral frame and the film of stand connection or fabric are continuous structure.
This utility model is when using, and is identical with the application of existing lumen of artery inner support, also is through stent delivery system the lumen of artery inner support to be sent into lesion region.
Description of drawings
Fig. 1 is the structural representation of the lumen of artery inner support of this utility model, and 1 is peripheral frame, and 2 is middle bracket, and 3 is stand connection, and 4 is film or fabric.
The specific embodiment
Lumen of artery inner support as shown in Figure 1 is formed by connecting through stand connection 3 peripheral frame 1 and middle bracket 2, and peripheral frame is a Z type structure; Diameter 38mm, middle bracket diameter 30mm, peripheral frame diameter and middle bracket diameter ratio are 1.27; Peripheral frame length is 30mm; Middle bracket length is 100mm, and peripheral frame length and middle bracket length ratio are 0.33, and the peripheral frame edge is respectively 30mm and 40mm far from the distance at homonymy middle bracket edge; The length of connector is 5mm, and the fabric that covers middle bracket is mutually continuous with the fabric that covers stand connection and peripheral frame.
This utility model can be avoided the generation of I type internal hemorrhage due to trauma in the gap between middle bracket outside sealing middle bracket and the aneurysm wall, improves the success rate of stent in the treatment.
The foregoing description is that the concrete scheme of this utility model is given an example, and protection domain is limit according to claim.
Claims (5)
