<p>Vascular function and structure is maintained or improved by long term administration of physiologically acceptable compounds which enhance the level of endogenous nitric oxide or other intermediates in the NO induced relaxation pathway in the host. Alternatively, or in combination, other compounds may be administered which provide for short term enhancement of nitric oxide, either directly or by physiological processes. An intramural process is provided for preventing restenosis by introducing precursor amino acid(s) through the balloon lumen (14) into the interior chamber (13) of the balloon (12). During inflation, the balloon (12) presses outwardly against the vessel wall (15) and the precursor amino acid(s) are introduced into the vessel wall (15).</p> |
