A kind of sacculus for biological body vessel bifurcated lesions and application thereof and operation method

Technical field

The present invention relates to field of medical technology, and in particular to a kind of for treating the ball of biological body vessel bifurcated lesions Capsule, in particular to sacculus for the treatment of human vas bifurcated lesions and application thereof and operation method.

Background technique

In organism, especially lumens such as the intracorporal blood vessel of people, respiratory tract, alimentary canal, ear canal, nasal cavity exist a large amount of Branch line, but due to the special air-flow and liquid flow characteristics of branch, such branch is the district occurred frequently of all kinds of obstructions and infection Domain.It is one of the therapeutic modality quickly grown at present using the interventional therapy of bracket or sacculus.

Bifurcation coronary artery accounts for about the 20-30% in Coronary Artery Disease Intervention Treatment field, is common clinical problem, simultaneously It is also most challenging one of the lesion in percutaneous coronary intervention field.The treatment operation difficulty of bifurcation coronary artery Greatly, success rate of operation is low, and complication rate is high, and long-term effect is poor.

Medicine-coated balloon is a kind of intervention therapeutic apparatus, using sacculus as anti-cell proliferation agents carrier, passes through sacculus Anti-proliferative drugs are discharged to coronary blood tube wall when expansion, to play the effect for inhibiting blood vessel endothelium hyperplasia.

Coronary artery stent implantation is the mainstream therapeutic modality of current treatment bifurcation coronary artery.Such as Percutaneous coronary intervention for coronary bifurcation disease:11th consensus document from the European Bifurcation Club(Eurolntervention；2016, ) and Contemporary Approach to Coronary Bifurcation Lesion Treatment Vol12:38-46 (JACC:Cardiovascular Interventions；2016, Vol9:1861-78) etc. coronary artery is disclosed in articles The operating method of Stent reached common understanding.

In fact, the operation diagnosis and treatment of the stenter to implant in bifurcated lesions coronarius, presently, there are time-consuming, step is numerous Trivial situation needs refigure shape in the blood vessels and, time on urgent, sky adherent with blood vessel to the bracket being implanted into advance Between it is upper narrow, there is in the recent period and uncertainty in Long term therapy.

In the treatment of bifurcation coronary artery, proximal end optimisation technique (Proximal Optimal Technique, POT) be it is a kind of after stenter to implant in the treatment means of bifurcated proximal row balloon expandable.The advantages of POT is operated is that bracket is close Shaping is held, branch openings are charged into and covered to utmostly main branch bracket mesh, guarantees that bracket is adherent.POT technical essential: it 1. selects Non-compliance sacculus；2. Balloon size will be more than bracket ruler diameter；3. positioning.The concordant branch openings lower edge of balloon distal is horizontal, closely End does not get higher than bracket；4. sacculus is expanded with middle pressure.The surgical procedure of proximal end optimisation technique needs operative doctor in sacculus It is more that above frequent switching, complex steps, uncontrollable factor are operated with bracket.

The treatment means that another kind uses in the prior art are that side branch patch actively shifts single-side stand technology (Active Transfer of Plaque, ATP), the specific steps are that: 1. main branch and branch respectively enter the 2. preset bracket of main branch of seal wire, Branch is placed in sacculus, and expanding (sacculus waist disappearance+1atm) makes patch be transferred to main branch.3. main branch under bifurcated balloon expansion state Bracket is to name pressure 4. bifurcated balloon negative pressure of release, main branch bracket sacculus negative pressure；5. exit bifurcated balloon, it can retain or withdraw from point Branch seal wire；6. main branch bracket sacculus is expanded again, guarantee the adherent of bracket.The existing single-side stand art formula of ATP art formula is easy to operate Advantage, and have both the unobstructed advantage of double bracket art Shi Bianzhi simultaneously.Equally, the surgical procedure of ATP art formula needs operative doctor to exist In sacculus and support operation, frequent switching, complex steps, uncontrollable factor is more.

Especially as to the most common Stent of vascular bifurcation lesions treatment, the biggest problems are that, Implantation Time Long, complex steps require high, implantation of the simplest single-side stand to bifurcated lesions blood vessel to the operational capacity of operative doctor, With regard to needing eight or more operating procedures.

At the same time, bare ball capsule (non-load medicine ball capsule) technology includes: in coronary artery bifurcated lesions technical difficult points

1. the bifurcated lesions of pair plaque load weight carry out single balloon angioplasty, bifurcated lesions are drawn by patch displacement The branch vessel risen, which is involved, may cause interventional procedure center myocardial ischemia, after blood vessel balloon expandable, if without bracket Support or anti-proliferative drugs locally discharge, then there may be the restenosis of very big probability.

2. when need two sacculus bifurcated lesions main branch vessel and branch vessel simultaneously expanded when how as early as possible Make two sacculus tail end alignment, and avoids balloon expandable caused by human factor as far as possible during balloon expandable process or shrink not It is synchronous.

3. the high recurrence rate of reangiostenosis and thrombus.

It is positive by being played for the therapeutic effect for improving bifurcation coronary artery if can solve the above problem Effect.
