Abstract
A filter comprising a porous material is arranged in a generally conical shape having an expandable base and a vertex. A reservoir tip is located at the vertex for collecting filtered embolic material. The tip communicates with a distal port and lumen of an aspiration tube for removing embolic material under vacuum. A vessel occluding device comprising a non-permeable material having an expandable conical shape and communicating with an aspiration tube is also disclosed. Methods of using the filter and occluding devices for protecting a patient from embolization during cardiovascular procedures are described.
