Background
With the improvement of living standard, coronary heart disease becomes the most common heart disease, mainly due to myocardial dysfunction or organic lesions caused by coronary artery stenosis and insufficient blood supply, so it is also called ischemic cardiomyopathy. At present, the coronary heart disease mainly has three treatment schemes of drug therapy, percutaneous transluminal vascular intervention therapy and cardiac surgery bypass surgery. Percutaneous transluminal vascular interventional therapy has become a main treatment means of coronary heart disease due to the characteristics of small trauma, quick recovery, capability of rapidly eliminating coronary artery stenosis, relieving myocardial ischemia and the like.
In the existing interventional therapy, a balloon is generally used for delivering a stent to a position of a stenosed blood vessel, the balloon is used for expanding the stent, and the elasticity of the blood vessel is used for fixing the stent in the blood vessel.
However, the expanded diameter of the stent is constant due to the difference in the thickness of the fat accumulation in the blood vessel. Therefore, fat piles up thick position in the blood vessel, and the protruding of outside blood vessel is comparatively serious, and to some special crowds, like the old person, its self vascular wall elasticity is not enough, supports the back through the support, though the blood vessel is unobstructed, but, the junction of bulge and the bulge that does not becomes weak point, appears breaking easily.

and pumping out the liquid in the independent capsule body and pumping out the capsule body.
The invention has the beneficial effects that: the balloon is divided into more than 2 independent balloon bodies, and the pressure in each independent balloon body is independently controlled by the pressure control device. Before using, according to individual situation, set up the internal pressure threshold value of independent bag, in the use, after the internal pressure of independent bag of one-to-one control reached pressure threshold value, stopped continuing to increase to it is different according to individual vascular wall elasticity, set up each different scheme. The resulting stent is different from the final cylinder of the prior balloon. Depending on the packing, a column of multiple diameters may be present. Under the prerequisite of expansion blood vessel, guarantee that individual vascular wall's flexible condition is in controllable within range, guarantee that individual blood vessel is difficult for breaking. The balloon expansion device solves the problem that the vessel wall is easy to rupture due to the fact that the vessel wall is easy to excessively expand because balloon expansion in the prior art is only based on experience, and has the advantages of being simple in structure and good in effect.
