Description
Technical field
The present invention relates to a kind of interventional medical device.
Background technology
Interventional treatment is the important means of the arteriovascular diseases treatment to grow up for nearly more than 30 years.70 years last century
In generation, there is balloon expanding technology, it is under the guiding of medical imaging device, is inserted into foley's tube with Percutaneous Techniques
The narrow positions of blood vessel, carries out balloon expandable expansion under stringent monitoring, is expanded the narrow positions of blood vessel, so as to recover
Lumen diameter.Although sacculus can eliminate the narrow of blood vessel, due to expansion blood vessel elasticity retraction, cells of vascular wall hyperplasia and
The reasons such as endangium tear, the incidence of operated vessels restenosis is up to 30%~50%.The eighties in last century, bare mental stents
Coming out, torn by repairing inner membrance, the incidence of reangiostenosis reduces, but still 30% or so.At the beginning of 21 century, medicament elution
Stent puts into clinical practice, and slowly release can be with inhibition of cell proliferation for medicine, and it is left that Restenosis incidence is reduced to 5%
It is right.Although the in-stent restenosis incidence of bracket for eluting medicament is remarkably decreased, it also has some defects.With prolonging for time
Long, the use of bracket for eluting medicament may increase advanced thrombus and be formed.In addition, after bracket for eluting medicament implantable intravascular, need to take
With aspirin and Effect of Clopidogrel in Treating, the two has certain bleeding risk.
Either balloon expandable is performed the operation, or stent implantation surgery, side effect can be all caused to a certain degree, such as inflammation, blood
The tear of pipe inner membrance, vascular cell hyperplasia etc., so as to cause reangiostenosis.Therefore, it is necessary to resist to lesion vessels conveying is certain
Inflammation, anti-cell proliferation agents.Oral or drug injection is most common method, although it has necessarily to suppressing reangiostenosis
Effect, but have very big side effect to normal blood vessels.And realize and one kind would is that to administration in time after lesion vessels expansion
Simply, quickly and effective method.But the prior art there is not yet such effective method.
