Abstract
The utility model discloses a kind of conduit for the clinical medical coronary artery bifurcated compressing of coronary heart disease, it is characterized in that, including sophisticated (1), light tight Y types portion (2), push rod (3) and tail end of conduit (4), wherein, set in the divergent ends in light tight Y types portion sophisticated (1), the other end is fixedly connected with push rod (3), push rod end connecting conduit tail end；Catheter interior sets cavity, can be after Percutaneous coronary interventions bifurcated lesions, at the separated mouth of appearance, bifurcated ridge during remaining scaffolding thread suspension, the simple efficient scaffolding thread that suspension is oppressed by this conduit, reduce and separate mouth ISR and thrombus in stents occurrence risk, so as to improve the clinical prognosis of coronary heart disease bifurcated lesions patient.
Description
Technical field
The utility model belongs to coronary heart disease technical field of clinical medicine, and in particular to one kind solves coronary heart disease bifurcated lesions and connect
By, compared with ISR in high trestle and the device of thrombus in stents occurrence risk, especially being solved after Percutaneous coronary intervention
Complicated bifurcated lesions receive the compressing conduit of more scaffolding thread suspension at bifurcated ridge after double bracket art formula.
Background technology
Bifurcation coronary artery accounts for percutaneous coronary as the targeted common lesion of percutaneous coronary intervention (pci)
The 15~20% of arterial Interventional Therapy total amount.Because there is Bian Zhiyi occlusions, big, the ISR risk height of surgical technic difficulty etc. in it
Problem, makes one of lesion that percutaneous coronary intervention is most challenged.In addition, the permanent support for being covered in side branch ostium
Silk is the main risk factor for causing postoperative side branch occlusion.These deficiencies add PCI bifurcated lesions to a certain extent
The risk of failure.
At present, after bifurcated lesions Percutaneous coronary intervention, often there is side branch ostium, scaffolding thread is not adherent at bifurcated ridge
Phenomenon.Double sacculus are the main method for handling such problem at present to kiss expansion.Double sacculus are comprised the following steps that to kiss expansion, first
First sacculus first is sent into along the seal wire in branch vessel, then second sacculus is sent into along the seal wire in main branch vessel again, will
Two sacculus are placed on the crotch of bifurcated lesions simultaneously, and kiss is expanded by dilatation balloon, realize opposite side branch mouthful, at bifurcated ridge
Suspension holdfast silk extruded.But, if the seal wire in branch vessel is if proximally hole is passed through, even if having carried out ball
Capsule is expanded to kiss, and it is not adherent to there will still likely be more scaffolding thread at bifurcated ridge.And with the passage of Post operation time, endothelium
Cell is easy to travel to not adherent scaffolding thread, increases the ISR occurrence risk of branch openings.Therefore, double sacculus expand kiss
Open treatment side branch ostium, bifurcated ridge scaffolding thread not adherent, less effective.In addition, also pole holds the scaffolding thread being suspended at bifurcated ridge
The generation for being easily caused thrombus in stents is possible, or even causes fatefulue harm to sufferer.Recently, the expert such as Foin reports point
Fork lesion is after the treatment of single-side stand art formula is received, and the main Zhi Jinduan of bifurcated lesions, branch openings are shown in a large amount of not adherent supports
Silk.Referring to Foin N, Secco GG, Ghilencea L, Krams R, Di Mario C.Final proximal post-
dilatation is necessary after kissing balloon in bifurcation
stenting.EuroIntervention.2011.7：597-604.
The adherent fraction defective of scaffolding thread that research discloses at bifurcated ridge is up to 51.5%, kiss is expanded by the way that sacculus is double, Shang You
27.1% scaffolding thread is not adherent.Even if being expanded after the last optimization by improved near-end, still there is 24.3% fraction defective.Many institutes
Known, these not adherent scaffolding threads are that patient receives after percutaneous coronary intervention (pci) to occur in support in narrow, support
The Major Risk Factors of thrombus.
The content of the invention
In order to overcome the shortcomings of that existing balloon expanding technology can not be fully solved at bifurcated ridge remaining not adherent scaffolding thread, this
Utility model, which is created, provides a kind of new coronary artery bifurcated compressing conduit, and the conduit can not only thoroughly solve side branch mouthful, at bifurcated ridge
Not adherent scaffolding thread problem, and main branch vessel proximal stent deformation, Yi Jiyin caused by can avoiding after double balloon expandables
The adherent harm such as bad of this and the abnormal coronary artery hydrodynamics and scaffolding thread that cause.
To reach above-mentioned purpose, the utility model uses following technical scheme：
A kind of conduit oppressed for coronary artery bifurcated, it is characterised in that including sophisticated (1), light tight Y types portion (2), push
Bar (3) and tail end of conduit (4), wherein, set in the divergent ends in light tight Y types portion sophisticated (1), the other end is fixedly connected with push rod
(3), push rod end connecting conduit tail end；Catheter interior sets cavity.
Preferably, the cavity can at least accommodate two percutaneous coronary plastys and guide seal wire, can be single or two
Cavity.
Preferably, the push rod is made up of hard material, with extremely strong push performance and support performance, described impermeable
Light Y types portion is made up of hard material, and the tip is made of a soft.
Preferably, the tip length is 1~10 millimeter, the forked section in light tight Y types portion and non-forked section difference
Long 1~10 millimeter, it is 90~120 centimetres to push pole length, and tail end of conduit is 10~30 centimetres.
Preferably, the tip is tapered, and external diameter gradually increases from small, with light tight Y types portion junction largest outside diameter；Point
End may also be cylindricality.
Preferably, in addition to tail end of conduit, push rod largest outside diameter in whole conduit, push rod can be extended through
5French and the above guiding catheter.
Preferably, the separated angle in the light tight Y types portion is acute angle or right angle.
Preferably, the catheter surface scribbles hydrophilic polymer coating.
Preferably, the tail end of conduit is provided with screw socket.
The utility model has advantages below compared with prior art：
1) the utility model can after Percutaneous coronary interventions bifurcated lesions, when occur bifurcated mouthful, at bifurcated ridge it is residual
During remaining not adherent scaffolding thread, it is simple it is efficient not adherent scaffolding thread is oppressed by this conduit, reduce bifurcated mouthful ISR and
Thrombus in stents occurrence risk, so as to improve the clinical prognosis of coronary heart disease bifurcated lesions patient.
2) the light tight Y types portion in the utility model is made of hard material, can be played very in catheter procedure is pushed
The effect of not adherent scaffolding thread is oppressed well, different angle designs are concurrently there are, and can meet clinically different angles of forking
The lesion of degree, makes compressing best results.
3) there is conduit described in the utility model independent inner chamber or double inner chambers by two seal wires to design, and can allow and lead
Pipe easily reaches bifurcated ridge part.
