Stent
|
||||
| A stent is a small tube made of latticed stainless steel wire which is used to support and hold open a blocked or narrowed artery. The doctor uses a balloon catheter to manoeuvre it into place - this is similar to the catheter used for the angiogram, except it has a small, deflated balloon inside the stent at its end. Once in place the balloon is inflated, which expands the lattice of the stent against the walls of the artery. The balloon is then deflated and removed while the stent remains to hold the blood vessel open and restore the blood flow. | ||||
