Half open stent of blood vessel and bifurcation free angle balloon comprising the same

摘要

The present invention relates to a half-open stent unit and a free angle balloon catheter comprising the same, and more particularly, to a stent unit and catheter comprising the same, wherein the stent unit is arranged in a main and a bifurcated blood vessel to simultaneously expand the vessels in cases such as stenoses caused by thrombi, and a free angle balloon catheter which adapts itself to a wide variety of angles in bifurcated blood vessels for insertion into the main blood vessel and the bifurcated blood vessel, such that the half-open stent unit expands in correspondence to the expansion of the free angle balloon catheter with no mutual interferences therebetween. The present invention has advantages in that the half-open stent for the main blood vessel and the half-open stent for the bifurcated blood vessel are inserted into the main blood vessel and the bifurcated blood vessel at the same time to simultaneously expand them, and the open shapes of the half-open stents prevents mutual interferences between the half-open stent for the main blood vessel and the half-open stent for the bifurcated blood vessel, the free angle balloon catheter unit for installation of the half-open stents is controlled to have a wide variety of balloon angles to be adapted to the various angles of the main blood vessel and the bifurcated blood vessel, and the half-open stents provide for installation in the blood vessels in an accurate manner.
