Abstract

The present invention involves an expandable element with an outer sticky surface. The expandable element may be in the form of a balloon with deflated and inflated configurations. The expandable element serves to both dilate a lumen in a blood vessel thereby opening it and to exert force upon the sticky surface in order to press it into apposition against a vessel wall. The outer sticky surface may be provided directly upon the expandable element or on a separate outer sheath that conforms to and follows the contours of the expandable element. The sticky surface may take the form of a biochemical composition and/or a mechanically abrasive structure such as microhooks, hairs, mesh netting, etc. Optionally, additional expandable elements may be provided proximal and distal to the main element to occlude blood flow on either side of a lesion in order to better trap emboli for collection.
