Angioplasty: Types, Procedure Details and Cost Angioplasty is a minimally invasive procedure used to widen
blocked
or
narrowed
arteries.
It

temporarily inserting and inflating a tiny balloon where your artery is clogged to help improve blood flow. Angioplasty with stenting is a similar procedure that also involves placing a small wire mesh tube called a stent at the site of the blockage to help keep your artery open.
