Description
Technical field
This utility model is related to medical intervention consumptive material field and in particular to a kind of coronary artery bracket.
Background technology
At present, China is considered as the most country of Patients with Cardiovascular/Cerebrovascular Diseases in the world, and its market potential enjoys medical treatment
The favor of apparatus manufacturer.In the treatment of coronary heart disease, the coronary artery in infraction places an intravascular stent, i.e. a kind of implantation blood
The metal mesh opening tubular device in pipe Stenotic pathologic change area, makes blood flow become unimpeded, is presently the most effective and conventional treatment
Method, the clinical efficacy of stent in the treatment coronary heart disease is obvious to all, but it also has shortcoming, and support is after implantation during 6-8 month
May occur in which in-stent restenosis, that is, occur blocking again, the incidence rate about 20% of metal rack age restenosiss, existing heart props up
The tinsel that frame is mostly rhombus grid structure is constituted, and also there is compliance, radial support power and transmitting axle force performance bad
Problem, and the cardiac stent blood vessel contact area of diamond structure is uniformly, stress is less, be subject in the blood vessel blood flow effect or
The impact of person's human body aggravating activities easily causes displacement, it could even be possible to falling into ventricle, seriously threatens patient health.
Utility model content
The purpose of this utility model is to provide a kind of coronary artery bracket, above-mentioned multinomial is lacked with solve to lead in prior art
Fall into.
A kind of coronary artery bracket, including rack body, described rack body is made up of the waveform unit closing, described wave
It is equipped with ω shape connector at the crest of shape unit and trough, be provided with 2-3 trough or crest between described waveform unit
Support bar, the middle part of described support bar is provided with the w type flex connector of horizontal stroke, and the middle-end of described w type flex connector is longer than two ends
1-2mm, the axial direction between each waveform unit connects through support bar and realizes, and is provided with glutin and applies outside described rack body
Layer, described gelatin coated surface is provided with c-myc antisense oligonucleotides layer by adsorption.
Preferably, described rack body is Nitinol.
Preferably, described rack body medial surface is provided with a nanometer silver coating, and described nanometer silver coating surface is provided with heparin layer.
Preferably, the middle-end of the described w type flex connector part longer than two ends is provided with metal carbonyl coat.
Preferably, described metal carbonyl coat is stiff cochrome material.
The utility model has the advantage of: rational in infrastructure, easy to use, material therefor good biocompatibility, through so
The coronary artery bracket compliance arriving of design is strong, and radial support power is good, transmitting axle force excellent performance, and the adsorptivity using glutin will
, on glutin layer, c-myc antisense oligonucleotide is at coronary lesions position for the permanent absorption of c-myc antisense oligonucleotide
Gradually discharge, play anticoagulation and the effect of the smooth myointimal hyperplasia of suppression, reach in minimizing art arteria coronaria acute occlusion and permanent
Prevent the purpose of arteria coronaria postoperative restenosis, the use of nano coating can reduce the adventitious deposit of lipid, heparin layer can dissolve
Small thrombosis in blood, the design of metal carbonyl coat makes the front end of w type flex connector bend to tubulose in rack body
When have certain protrusion angles, can contact with internal blood vessel, increase stress between the two, crystallized ability is strong, effectively prevent
The problem that cardiac stent easily shifts under various conditions.
