Weave the silk at the mechanical properties of each section of axial and all ascending contained angles adjustment support through what first portion and second portion were woven in the change, the blood flow flow direction in improving the aneurysm when realizing that the blood flow direction is rebuild, satisfies support to the demand of compliance and keep unobstructed by normal branch artery that support covered.
Description
Technical field
This utility model relates to manufacture technology field of medical appliance, particularly relates to a kind of support.
Background technology
At present, the disease that blood vessel is common mainly has stricture of artery, aneurysm etc., if these diseases are controlled not in time
Treatment may result in blood vessel blockage, tumor body ruptures, by the life security of serious harm patient.
Aneurysm is the pathological changes due to arterial wall or damage, shows as arterial blood tube wall limitation or diffusivity expands
Open or bulging.Aneurysm constantly grows under the impact of blood flow, when increasing due to blood pressure or other factors cause
Aneurysm rupture time, it may occur that drastically hemorrhage, ruptured aneurysm has high cause mortality rate.Tremulous pulse
Tumor can occur the different parts at health, most commonly cerebral aneurysm and abdominal aortic aneurysm.
Aneurysm is generally formed in vessel branch, bifurcated or crooked position, and its reason is: based on these
The Hemodynamic Factors at position, i.e. axially blood flow forms shear stress to the impact of blood vessel far-end, causes blood
The destruction of pipe elastic layer, forms cryptomere projection, and shear stress stimulates and promotes impaired vascular endothelial cell simultaneously
Merisis, and then grow into aneurysm, it can be seen that shear stress is the fundamental cause of Aneurysmformation.
Treating aneurysmal target is to reduce the risk of aneurysm rupture, and the most basic method is to realize parent to carry
The healing of tumor tremulous pulse, so that the reconstruct of arterial wall anatomical structure.Treat aneurysmal method and include following several:
1. surgical clamp closes aneurysm, closes aneurysm neck by operation of opening cranium metal clip sub-folder；
2. intravascular Interventional Treatment, utilization can shirk turn, and (or micro-metallic coil or other embolism materials are as can
Free sacculus, curable liquid etc.) thromboembolism aneurysm；
3. intravascular Interventional Treatment Stent.
Above-mentioned several method is broadly divided into surgical intervention and vascular interventional treatment, due to surgical intervention traumatic,
High risk and high complication, intravascular Interventional Treatment is increasingly becoming the main method of aneurysm treatment, and this is main
Intravascular Interventional Treatment to be had benefited from has that wound is little, few intercurrent disease, safety is high, patient suffering is few, easy
The advantages such as acceptance, the hospital stays is short, year high state of an illness weight is also resistant to.
Can shirk Coil embolization tumor chamber is that couple punctures, and imports blood vessel by microtubular, by metal elastic
It is interior to clog aneurysm that spring coil inserts aneurysm, thus stops blood flow to flow into aneurysm.Coil embolization material
Design with microtubular can arrive the arteriocerebral aneurysm pathological changes of tortuous complexity, and by the filling in tumor chamber
Stop blood flow impact, but this thromboembolism exists the risk causing aneurysm cavity to expand further and rupture.
Intravascular Interventional Treatment Stent is with treatment and to reconstruct aneurysmal mother by implantable intravascular support
Body parent artery, this intravascular stent must have the following characteristics that
1) support can by compression load micro-carrier inner chamber, compression after-poppet sufficiently flexible can by tortuous,
Very thin, complicated cerebrovascular is transported to reach target；
2) there is enough compliances after stenter to implant, comply with tortuous cerebrovascular；
3) hemodynamics in support appreciable impact aneurysm, maintains parent parent artery to be covered by support simultaneously
Normal bifurcated artery unobstructed of lid.
But, for some requirement above-mentioned, existing support still cannot all meet, such as cerebral aneurysm
Treatment, due to the tortuous complexity of cerebrovascular anatomic form, the pliability for support requires higher, in order to
Meet the demand of pliability, support Design uses a small amount of metal cover and open grid, but such
The mesh density of support is relatively low, it is impossible to well cover Aneurysmal neck so that support cannot change effectively
Hemodynamics in aneurysm, and there is adherent bad, intracavity discounting etc. at curved blood vessel position and ask in its support
Topic.The defect existed in view of above-mentioned support, needs design to invent more preferably support.
Utility model content
The purpose of this utility model is to provide a kind of support, to solve the demand in order to meet support pliability,
By support Design be mesh density and metal coverage rate low, it is impossible to preferably cover Aneurysmal neck, cause
Frame can not realize blood flow very well and guide the problem rebuild.
In order to solve above-mentioned technical problem, this utility model provides a kind of support, and described support includes:
