Description
Technical field
The utility model is related to medical treatment consumptive materials technical field, and in particular to a kind of mounting system of protection branch vessel.
Background technology
Hemadostewnosis, occlusion are the diseases of a kind of high disability rate and high mortality.It is hard for vascular diseases especially artery
Change, narrow and occlusive disease, intravascular Interventional Treatment and Stent are one of main treatment methods.The technology is to prop up
Frame reaches diseased region through induction system, then stretched to extrude patch to expand diameter, the support tube of inner chamber to extravascular
Chamber and reach treatment hemadostewnosis purpose.Clinically quite a few hemadostewnosis, Occlusion involve vascular bifurcation.Sacculus
Bifurcated spine and stenotic lesion displacement can cause branch vessel oral area narrow or even occlusion when expansion and stenter to implant, cause branch
The ischemic of blood vessel blood supply tissue, and cause serious adverse consequences clinically.On current interventional technique, using branch vessel oral area
Two kinds of methods of seal wire protection technique and double bracket technology are to prevent this complication.
The technology of seal wire or sacculus within branch is placed in branch's seal wire protection before main support discharges.Because protection is led
Silk and sacculus need perforating branches frame mesh to send seal wire to side Zhi Yuanduan, entered outside main support when branch's oral area is impaired after support release
And push sacculus even while support in while the implantation of branch oral area row balloon dilatation and stenting reconstructed with the negativity for improving branch's oral area.
Double bracket technology is to ensure serial hand that branch vessel blood flow is unobstructed in main branch and each Stent Implantation of branch vessel
Art method.Such technical operation is relative complex, difficulty, and seal wire needs to deliver to side branch completion by individual layer even three layers of supporting structure
Sacculus is to kiss art.Merge that calcification, tortuous, main branch-branch vessel angle be excessive or too small in blood vessel, branch's oral area Serious Stenosis very
To when occlusion, it is extremely difficult that seal wire is again introduced into side branch vessel.Seal wire can not enter side Zhi Kaizhan by supporting structure
Follow-up side branch balloon dilatation and stenting treatment, is influence bifurcated lesions success rate, brings serious bad clinical events
Main cause.
