The invention relates to a
balloon expandable
stent with a side-hole channel, which belongs to the technical field of medical devices implantable into the
blood vessel of
human body. One end of the
balloon is communicated with a
balloon catheter that can inject and suck out contrast agent; an expandable compression
stent is arranged outside the balloon; a main intracavity channel and an intracavity sub-channel are respectively arranged in the balloon and the
balloon catheter; one opening of the main intracavity channel is positioned at the side wall of the
balloon catheter, and the other opening is positioned at the top of the balloon; one opening of the intracavity sub-channel is positioned at the side wall of the
balloon catheter, and the other opening is positioned at the side wall of the balloon; the expandable compression
stent is provided with a side hole opposite to the side-wall hole of the balloon. The invention has the characteristics of simple structure, convenient operation and use, time saving and safety; meanwhile, the stent can break through the forbidden zone that the
interventional therapy can not proceed due to the bifurcation and
lesion of the
blood vessel of brain, can simplify the steps of treating the bifurcation and
lesion of the coronary
artery, lower the operation risk and difficulty of stent-aiding
embolism operation for wide-necked aneurysms, enhance interventional
embolism /
surgical clipping ratio, and alleviate patients' wound and pain.
