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
- pyeloplasty using a detachable inflatable balloon stent positioned via a cystoscopic transvesicular approach.
Angioplasty balloon catheters
Balloon catheters used in angioplasty are either of Over-the-Wire (OTW) or Rapid Exchange (Rx) design. Rx catheters nowadays are about 90% of the Coronary Intervention market. While OTW Catheters may still be useful in highly tortuous vascular pathways, they sacrifice deflation time and pushability. 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.
Ureteric (pyeloplasty) balloon catheter
