<P>PROBLEM TO BE SOLVED: To provide an intravascular device for keeping open a previously constricted site within a vessel and for minimizing tissue debris at such a site from closing off the vessel. <P>SOLUTION: The device 10 includes an expandable substantially tubular body 11 defined by a framework 12 having a plurality of openings 13. The device also includes a flexible netting system 14 having a structural design for extending across each of the openings. Such a design allows the netting system to expand along with each opening in the framework to minimize release of tissues debris at the site from closing the lumen of the vessel. The netting system can include a plurality of pores to permit communication between fluid flow within the vessel and the vessel wall, and at least one pharmacotherapeutic agent for the treatment or prevention of certain conditions. A method for placing the device at a site of interest is also provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
