Abstract
Post-interventional neointimal hyperplasia in arteries is treated by the application of ultrasonic energy. Usually, an intravascular catheter having an interface surface is positioned at a target site in the artery which has previously been treated. The interface surface is vibrationally excited to apply energy to the arterial wall in a manner which inhibits smooth muscle cell proliferation in the neointimal layer.
