Abstract
An atherectomy apparatus and method is disclosed for the purpose of surgical excision of atheromas which typically consist of plaque deposits that cause narrowing (stenosis) of an artery. The apparatus, called a pullback atherectomy catheter, cuts and collects obstructive material into a collection chamber as the catheter is pulled back through obstructive material within a human vessel such as an artery.
