Abstract:
A method for entrapping plaque particles against a vascular wall at a predetermined intravascular site, comprising the steps of:providing a radially outwardly deformable, tubular sheath having a proximal end and a distal end; providing an intravascular deployment catheter having a proximal end, a distal end, and a lumen extending therebetween; attaching the sheath proximal end to the deployment catheter distal end; providing a radially outwardly deformable stent; disposing the stent within the sheath; introducing the deployment catheter into the vasculature; advancing the deployment catheter through the vasculature to position the sheath at the intravascular site; and expanding the sheath against the vascular wall at the intravascular site to trap the plaque therebetween; wherein the step of expanding the sheath comprises expanding the stent along with the sheath, the sheath contacting the vascular wall and the stent contacting the sheath.
