Technical Field
The invention relates to the medical field, in particular to a blood flow guiding device with a coating.
Background
Hemangiomas are congenital benign tumors or vascular malformations in the skin and soft tissue that are formed by the proliferation of angioblasts during the embryo, most commonly at birth or shortly after birth. Residual embryonic angioblasts, active endothelial-like germs invade adjacent tissues to form endothelial spline cords, which are connected with the left blood vessels after the tube formation to form hemangiomas, and the intratumoral blood vessels are self-organized and are not connected with surrounding blood vessels. Hemangiomas can occur throughout the body, with hemangiomas that occur in the oromaxillofacial region accounting for 60% of the total body, followed by the trunk and extremities. Most of these occur in facial skin, subcutaneous tissue and oral mucosa, tissues such as tongue, lip, and bottom of mouth, and a few occur in jawbone or deep tissues. .
Today, the medical community has invented a "coating stent", which is placed in a blood vessel so that the hemangioma does not have blood flowing through for a long time, and the hemangioma dies naturally on the basis that no blood provides nutrients for the hemangioma, thereby achieving the therapeutic effect.
