The initial form of angioplasty was 'plain old balloon angioplasty' without stenting, until the invention of bare metal stents in the mid-1980s to prevent the abrupt closure that sometimes occurred plain old balloon angioplasty. [1] Bare metal stents were found to cause in-stent restenosis as a result of neointimal hyperplasia and stent ...
Balloon pulmonary angioplasty (BPA) is an emerging minimally invasive procedure to treat chronic thromboembolic pulmonary hypertension (CTEPH) in people who are not suitable for pulmonary thromboendarterectomy (PTE) or still have residual pulmonary hypertension and areas of narrowing in the pulmonary arterial tree following previous PTE. [1] [2]
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.
Balloon angioplasty is the inflation of a balloon (often part of an integrated medical device combining a balloon, guidewire, and stent) within the coronary artery to 'crush' the plaque causing the occlusion into the walls of the artery. Balloon angioplasty is still often performed as a part of PCI procedure, it is rarely the only activity ...
Aortic valvuloplasty, also known as balloon aortic valvuloplasty (BAV), is a procedure used to improve blood flow through the aortic valve in conditions that cause aortic stenosis, or narrowing of the aortic valve. It can be performed in various patient populations including fetuses, newborns, children, adults, and pregnant women.
Balloon sinuplasty is a procedure that ear, nose and throat surgeons may use for the treatment of blocked sinuses. Patients diagnosed with sinusitis but not responding to medications may be candidates for sinus surgery.
Boston Scientific's Flextome is the most widely used cutting balloon. Cutting balloons have also been used in the treatment of refractory or recurrent laryngotracheal stenosis, particularly in cases where a dense ring of circumferential fibrosis has formed in the trachea or either bronchus'.
Currently approximately one million stents are implanted annually worldwide. The balloon angioplasty augmented with the use of the stent has become the preferred treatment for atherosclerosis. However, the stent has not completely done away with restenosis after angioplasty, and improved procedures continue to be sought.
