Balloon catheter

Balloon catheter

A balloon catheter is a type of "soft" catheter with an inflatable "balloon" at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body. The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed.

Some common uses include:
*angioplasty or balloon septostomy, via cardiac catheterization (heart cath)
*tuboplasty via uterine catheterization

Angioplasty balloon catheters

Balloon catheters used in angioplasty are either of Over-the-Wire(OTW) or Rapid Exchange(Rx) design. When a balloon catheter is used to compress plaque within a clogged coronary artery it is referred to as a plain old balloon angioplasty or POBA. Balloon catheters are also utilized in the deployment of stents during angioplasty. Balloon catheters are supplied to the cath lab with a stent premounted on the balloon. When the cardiologist inflates the balloon it expands the stent. When the cardiologist subsequently deflates the balloon the stent stays behind in the artery and the balloon catheter can be removed. Stents that are used in conjunction with a balloon catheter are known as balloon expandable stents.
