What is Sirolimus stent?
stent is a hollow cylinder located inside the body to support walls or maintain a normal perimeter of the organ. Sirolimus or Rapamycin is a medicine that suppresses the immune system so that the body does not attack a new implant. Sirolimus, also called stent Eluting Sirolimus, is a stent that is filled with medicines. This helps to prevent the body from responding poorly to the new stent and causing new blockages. Sirolimus stent implantation is a minimally invasive surgery that usually allows the patient to return to life as usual in a short period of time. They can also be used to protect the function of other tubes in the body if, for example, pushed by cancer growth. The stents are located by means of an endoscope and inflatable balloon by a catheter. If the stent is to be placed in the coronary artery, the catheter is stretched peripheral artery; If the area that is stewed is in the digestive tract such as bile or pancreatic channel, it can be introduced through the esophagus.
Sirolimus stent is more efficient than a stent without drugs; It is also more effective than the angioplasty of the balloon or stent that contains a paclitaxel drug. Drugs in Siroli stent prevent the body over the production of cells as they are treated around the place of surgery. When a bare stent is used, it is likely that recurring stenting will be required to create excessive tissue that increases the chances of creating new blockages.
The location of the siroli stent is a delicate procedure, but generally causes the body very small trauma. As soon as the catheter with the endoscope and the angioplastic balloon is passed through the blood vessels or the digestive tract to the point of digestion, the balloon is inflated; This causes the stent expansion and pushing into the wall of the artery or channel. Only the location of the stent and entry into the body generally requires recovery.
Recent progress in the production of siroli stents have been made, resulting in drugs are stored in small pitsor in the metal of the stent instead of covering the entire surface. This leads to less direct contact between the polymer substance containing a drug and body tissue; This allows the use of a smaller amount of medicine-polymer, reducing the potential risks associated with drugs.
