Abstract
The invention relates a medicine-carrying cutting balloon dilating catheter. The medicine-carrying cutting balloon dilating catheter comprises a cutting balloon dilating catheter body and a medicine coating, wherein the cutting balloon dilating catheter body comprises a balloon, the surface of the balloon is provided with a plurality of blades, and the medicine coating is coated on the surfaces of the balloon and the blades. The medicine-carrying cutting balloon dilating catheter can cut plaques in vessels and fully dilate to be well adhered to arterial walls by pressing the plaques, so that not only subsequent inflammatory responses are reduced, but also the dilation of lumen reduces the restenosis rate. Besides, the medicine coating can restrain the intimal hyperplasia of the vessel inner surface which is damaged by squeezing. Particularly for a bended complex lesion location where a stent cannot reach, the superior advantages of the medicine-carrying cutting balloon dilating catheter are significant.
Description
Technical field
The present invention relates to medical instruments field, specifically, relate to the cutting sacculus dilating catheter that a kind of balloon surface is loaded with medicine.
Background technology
Cerebrovascular disease is all very high diseases of a kind of sickness rate, mortality rate and disability rate, is one of current mankind " three big killers " (cerebrovascular disease, cardiovascular disease and tumor).Cerebrovascular medium-sized artery stenosis or occlusion is to cause one of apoplexy most important reason.According to domestic 7 cities of finishing and 21 provinces rural area sacred disease Epidemiological study resulting estimate, about 2,000,000 people of national annual New Development apoplexy; Die from about 1,500,000 people of patients with cerebrovascular disease every year, survival number (comprising cured person) 600-700 ten thousand.In the patients with cerebrovascular disease of survival, about 3/4 in various degree disability brings tremendous influence and burden for patient, family and society.
Cerebral arteries produces stenosis or occlusion, very easily causes transient ischemic attack (TIA) and death.And the main predisposing factors that produces pathological changes is because three-hypers (hypertension, hyperlipidemia, hyperglycemia) disease on the one hand, moreover along with the increase at people's age, the blood vessel wall of human body artery can occur the atherosis arterial lumen that causes inevitably and narrow down gradually, when serious even obturation, cause cerebral ischemia or cerebral infarction.If cerebral ischemia longer duration, degree weigh, will cause brain cell necrosis.Therefore when being arranged, slight cerebral ischemia attack checks to have or not cerebral arterial stenosis that the serious or speckle ulceration if any stricture of artery should be considered the interventional therapy of cerebrovascular, guarantees health to remove a hidden danger.
Blood vessel sacculus in the cerebrovascular interventional therapy expands into the shape art and endovascular stent is implanted a kind of very important means that plasty has become the treatment cerebral arterial stenosis, and demonstrates vitality with superioritys such as its wound are little, safe, indication is wide, postoperative complication is few in the treatment of ischemic cerebrovascular.But the support that support is implanted in the plasty belongs to foreign body, if restenosis takes place in the support, then be difficult to treatment, moreover it is also higher to implant the plasty medical expense.More prior in fact is because cerebrovascular is more circuitous than the traveling of arteria coronaria blood vessel, and official jargon is more very thin, and caliber changes greatly, and support often can not reach complicated narrow diseased region, and at this moment the balloon expandable plasty just becomes main treatment means.
Therefore, need have a kind of sacculus dilating catheter can expand stenotic lesion fully, can also prevent neointimal hyperplasia, it is minimum that restenosis rate is dropped to, and replaces support to implant, and obtains good curative effect.
Summary of the invention
A kind of cutting sacculus dilating catheter of medicine carrying comprises cutting foley's tube body and medication coat, and described cutting foley's tube body comprises sacculus, and the surface of described sacculus is provided with a plurality of blades, and at the described medication coat of the surface-coated of sacculus and blade.
To achieve these goals, the invention provides following technical scheme:
A kind of cutting sacculus dilating catheter of medicine carrying, this foley's tube is the cutting balloon structure: there is blade on the surface of described sacculus.
Preferably, described sacculus be shaped as cylindrical or conical.
Preferably, the blade shapes on the surface of described sacculus is triangle or wedge shape.
Preferably, the material of described blade is medical macromolecular materials or metal material.
Preferably, described metal material is medical stainless steel, cobalt-base alloys, titanium-base alloy, marmem or noble metal.
Preferably, the quantity of described blade can be three, four or five.
Preferably, described blade is for being evenly distributed on balloon surface
Preferably, being connected between described blade and the sacculus can be the contact separation formula, also can be inserted.
Preferably, described medication coat is the medicine that suppresses neointimal hyperplasia, anti-angiogenic restenosis.
Preferably, the medicine of described medication coat is one or more in rapamycin (sirolimus), paclitaxel, the plain probucol of blood vessel titanium, the dexamethasone.
Preferably, described medication coat can be coated in cutting sacculus outer surface by the mode of spraying or dip-coating.
Preferably, the cutting sacculus dilating catheter of described a kind of medicine carrying is used for cerebrovascular, cardiovascular or peripheral blood vessel.
From above-mentioned technical scheme as can be seen, the cutting sacculus dilating catheter of medicine carrying can cut the speckle in the blood vessel in the embodiment of the invention, can fully expand simultaneously, the extruding speckle just can carry out good applying with arterial wall like this, not only reduced inflammatory reaction subsequently, the increase of tube chamber has also reduced restenosis rate; Moreover medication coat can suppress to be extruded the neointimal hyperplasia of impaired vascular inner surface, thereby also reduced restenosis rate.Especially in the crooked complex lesions that support can not arrive, demonstrate its superior characteristic.
