Claim:
1. A percutaneous interventional treatment apparatus comprising: an elongated catheter having a lumen, a proximal end portion, a distal end portion, an outer side wall, and a longitudinal axis; an interventional device operably coupled to the distal end portion of the elongated catheter; a filter operably coupled to the distal end portion of the elongated catheter and spaced from the interventional device relative to the longitudinal axis of the elongated catheter, wherein the filter is selectively collapsible and expandable about and between a collapsed position and a deployed position, and wherein the filter comprises: an actuator wire extending through the lumen of the elongated catheter and having proximal and distal ends, wherein, when the filter is in the collapsed position, pulling on the proximal end of the actuator wire exerts a force on the movable ring in a direction relative to the longitudinal axis of the elongated catheter that moves the movable ring towards the fixed ring; and wherein selective movement of the movable ring towards the fixed ring causes at least a portion of the tubular frame to expand radially, thereby selectively expanding the filter towards the deployed position.
