Brachytherapy -

A new form of therapy for relieving blockages in the coronary artery, and preventing restenosis in stents.  Brachytherapy applies a dose of radiation to the stenotic segment of the artery, generally delivered via a special catheter.  Controversy remains as to when the benefits of this new therapy outweighs the risks.
