Abstract
The utility model discloses a woven blood vessel stent, which is woven by a single elastic metal wire. The woven blood vessel stent comprises a circular tube shaped reticular stent body and an outer ring-shaped reticular skirt which is connected to the middle portion of the body, both the circular tube shaped reticular stent body and the outer ring-shaped reticular skirt comprise a plurality of transformable units enclosed by mesh wires, a plurality of arc-shaped wire curves are formed at two ends of the reticular stent body and the free end of the reticular skirt, mesh wires are in sliding contact connection at the cross points, and a layer of medicine coating which prevents restenosis of blood vessels is coated on the surface of the woven blood vessel stent. After expansion, the woven blood vessel stent of the utility model not only can maintain relatively high radial supporting force, but also has outstanding axial flexibility and vascular compliance. Further, the woven blood vessel stent is extremely low in radial shortening and moderate in surface coverage of metal. Simultaneously, the blood vessel stent with medicine coating can effectively reduce the incidence of restenosis, and can reduce the incidence of complication of patients after being planted with the blood vessel stent.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of braided blood vessel stent that is applicable to the outer ring network skirt of the band in the human vas interventional therapy field.
Technical background
Puncture shaping surgery, be called for short the PTA art, be under the guiding of medical imaging device, utilize puncture needle, seal wire and guiding sheath that the foley's tube of the support that is with deflation is injected human vas, and be transported to the angiostenosis place, expansion with sacculus, support is also strutted, and after sacculus shrank back and removes, the metal rack that produces plastic deformation was then stayed the original place, and embedded blood vessel, play the effect of blood vessel dilating.The method makes that the long-term efficacy of operation is good.
Angle from clinical use, the braided blood vessel stent design of the outer ring network skirt of a kind of ideal band will have following technical specification simultaneously: enough radial support power, good axial compliance, little radially bounce-back than and axial LVFS, moderate metal space occupied area is than (10%-20%) etc.A good support should reach effective unification in these areas.
The intravascular stent form of prior art has multiple, and they have their own characteristics each, and its purpose all is to improve the radial support intensity of support and axial function such as flexibility.But existing support is difficult to reach effective unification because of its structural limitation aspect these two, though some support expansion back support force is stronger, axially flexibility is not good enough, and metal surface coverage rate and axial LVFS are bigger; Though some support is better softness axially, radial support power deficiency, the metal surface coverage rate is less, causes vascular restenosis easily, so still remain further to be improved.
Summary of the invention
The purpose of this utility model is to provide a kind of and can keeps higher radial support power that the axially braided blood vessel stent of compliance and vascular compliance, the outer ring network skirt of the axial band that LVFS is very little, the metal surface coverage rate is moderate is arranged again well after expansion.
The technical scheme that realizes above-mentioned purpose is: a kind of braided blood vessel stent, wherein, form by single elastic metallic yarn braiding, comprise a tubular network body and an outer ring network skirt that is connected this body middle part, all comprise a plurality of deformable unit that surround by netting twine in tubular network body and the outer ring network skirt, at the two ends of network body and the free end of net skirt form a plurality of curved lines and turn, each netting twine is slidably contact connection at the place, cross point, the surface of described braided blood vessel stent evenly is coated with the medication coat that one deck can prevent vascular restenosis.
Above-mentioned braided blood vessel stent, its kind, between described outer ring network skirt and the network body shape in an angle, the free end of promptly outer ring network skirt outwards opens.
Above-mentioned braided blood vessel stent, wherein, the described support that is formed by single elastic metallic yarn braiding is its free state or typing state behind knitting forming, this support can be made axial elongation by radial compression under external force, recover its free state or typing state after the pressure relief.
Above-mentioned braided blood vessel stent, wherein, the angle between described outer ring network skirt and the network body is the 5-30 degree.
Above-mentioned braided blood vessel stent wherein, is coated with a plurality of opacity spike rings respectively on the netting twine of described network body different parts.
Above-mentioned braided blood vessel stent, wherein, described support uses towards the flow direction of blood according to the free end of outer ring network skirt.
Above-mentioned braided blood vessel stent, wherein, the composition of described medication coat comprises Organic substance carrier, additive, medicine.
The beneficial effects of the utility model are: this utility model is owing to adopted above technical scheme, make support after expansion, can keep higher radial support power, well axial compliance and vascular compliance are arranged again, the free end of the outer ring network skirt during use in the support is towards the flow direction of blood, help the fixing of support, prevent to be got excited by blood, simultaneously, the intravascular stent of band medication coat can reduce the incidence rate of vascular restenosis effectively, and reduces the generation of the complication of patient behind the implantable intravascular support.
