Abstract
An absorbable stent for placement at the locus of a stenotic lesion which is flexible and compliance for safe and effective delivery to the cite of a coronary obstruction, for example, and so as to avoid arterial rupture or aneurysm formation while under continuous stress of a beating heart. The stent is expandable from a reduced diameter configuration, which facilitates delivery to the cite of a targeted arterial obstruction, to an expanded configuration when disposed within the targeted area. The stent can be carried to the cite to be treated and expanded to its supporting diameter on any suitable expandable catheter such as a mechanically expandable catheter or a catheter having an inflatable balloon. The stent is formed so as to have a wall with pores and/or holes to facilitate tissue ingrowth and encapsulation of the stent. The stent will subsequently be bioabsorbed to minimize the likelihood of embolization of the dissolved material.
