Abstract

An intravascular filter is constructed to electrostatically capture and retain particles of a targeted type (for example fat or methacrylate emboli), even if those particles are physically small enough to slip through the filter in the absence of electrostatic attraction. Specific types of targeted particles are thereby captured and retained with improved efficiency, while permitting free flow of non-targeted particles. This improvement permits intravascular filters to be constructed with low-resistance, widely spaced filter elements. Accordingly, more targeted particles are captured, less thrombosis occurs, less pressure drop occurs across the filter, and perfusion or blood collection in downstream areas is maintained.
