Technical field
The invention belongs to medical instruments fields, are related to a kind of double sacculus branch of special type side branch for bifurcated lesions interventional therapy Frame system.
Background technique
Bifurcated lesions are relatively common in clinical practice.Have part " false " bifurcated lesions (main branch vessel has Serious Stenosis, Branch vessel does not have obvious stenosis) in carrying out interventional therapy, due to the displacement of patch, also become " true property " bifurcated lesions (main branch and branch vessel have obvious stenosis).Short-term effect, but long-term effect are improved for the interventional therapy of bifurcated lesions It is still undesirable.Bracket for eluting medicament can significantly reduce PTCA or and STENTS reangiostenosis.But for bifurcated lesions, main branch is again Stenosis rate is decreased obviously, but the restenosis of side branch and thrombus problem are still unresolved.The intervention of different types of bifurcated lesions is controlled The selection for treating strategy is most important, judges including lesion, technical tactic, the selection etc. of instrument.For coronary artery bifurcated Lesion is always Cardiac interventional doctor's facing challenges.
Bifurcated lesions according to the characteristic distributions of patch and it is main aid the border areas branch vessel angulation the case where, clinically have various partings, Including Lefevre parting, Duke parting, Satian parting, Sanborn parting, Medina parting etc..Various partings have spy Point, and exist and intersect.In simple terms, from the angular relationship of main branch vessel and side branch vessel, it is divided into Y type lesion and T-type lesion.It is right In Y type lesion, into side Zhi Rongyi, but patch is easy displacement, even if side branch vessel does not have lesion sometimes, it is also desirable to seal wire or Sacculus protection.For T-type lesion, patch is not easy to shift, but seal wire is not easily accessed side branch.No matter which kind of type lesion, just The not absolute T-type of the physical aspect at normal bifurcated mouth edge is Y type, i.e., from main branch vessel with certain radian to Side branch vessel transition, it is in the shape of a trumpet.
At present for the therapeutic strategy of bifurcated lesions, for the branch vessel of side, it is divided into and does not need seal wire protection, need It wants seal wire to protect, and needs balloon expandable.The protection of seal wire and the expansion of side branch sacculus are provided to prevention and treated in main branch Branch occlusion in side occurs in journey.Predilation in branch sacculus is conducive to branch vessel when subsequent seal wire enters across main branch bracket mesh, It carries out last to kiss expansion.In conjunction with the interventional therapy of main branch vessel, in simple terms, two type of single-side stand and double bracket can be divided into Type.
The bracket merging technology for bifurcated lesions common at present includes that (classical T support technology changes T-type support technology Good T support technology, necessity T support technology etc.), crush technology (including improvement crush technology, substep crush technology, Reverse crush technology, inverted crush technology etc.), Y type support technology is synchronized to kiss support technology, trousers skirt (Culotte) (" Interventional cardiology " second edition, the long-living chief editor of horse, the 37th chapter such as support technology and DK-crush technology P494-516, inverted crush stenting such as Figure 23).
From the point of view of current various art formulas, there are some clearly disadvantageous places.It is relative complex in addition to performing the operation, such as seal wire It is not easy to be passed into side branch vessel from main branch bracket mesh, sacculus passes through or expansion web may also at the moment rupture, other Also: one, possible damage side branch ostium or stent migration when seal wire pumpback；Two, branch seal wire in side enters from main branch bracket mesh Or main branch seal wire is passed through from the mesh of side branch bracket, all it cannot be guaranteed that seal wire in well under lumen of vessels central axes, with During balloon expandable afterwards, vascular wall stress has probabilistic influence；Three, there is unnecessary one layer at the branch ostium of side Or double layer of metal net, some main support both ends may have three-layer metal net, increase the chance of restenosis；Four, such as side branch bracket Prominent main branch is more, and sacculus is longer in main branch part, when main branch balloon expandable while branch bracket to while branch internal migration, increase to tube wall Damage, be easy to cause the tearing of inner membrance.Five, two sacculus parallel sections are excessive when expanding to kiss, and it is sharp to may cause opening Gap at angle is elongated, overextending at obtuse angle；Six, conventional balloon expansion and bracket release are not accomplished at opposite side branch ostium Physical aspect on arc-shaped transition area good fit and postoperative branch restenosis in side easy to form and one of the reason of thrombus； Seven, it is main in branch bracket at vascular bifurcation while main Zhi Shuanchong sacculus shape after extruding uncertainty etc..These problems The main reason for may be that operator is confined to current instrument, lack the amount for meeting physical aspect to bifurcated vessels opening Body bracket and sacculus customized, and the balloon-stent transportation system not being suitble to.
