Stenosis is the
narrowing of the coronary artery, which may
or may not be associated with chest discomfort or other symptoms.
In-Stent Restenosis is the renarrowing of a coronary artery
within a previously placed stent. Vascular Brachytherapy with
the Novoste™ Beta-Cath™ Syatem has been shown
to reduce the need for repeat procedures due to In-Stent-Restenosis.
