Abstract
The present invention relates to a medical device and a method of delivering a drug to a target circulation or tissue. The medical device has an expandable portion which is fabricated from a porous elastomeric material with a plurality of voids therein. The voids are loaded with drugs in various formulations. Upon inflation of the expandable portion, the overall diameter increases, the wall thickness decreases and, consequently, the voids are stretched to cause the drug to be expelled from the voids and into the bodily lumen or tissue adjacent to the medical device. The voids include any open volume within the expandable portion capable of containing the drug.
