Abstract
A removable, low profile, vascular filter system for capture and retrieval of emboli while allowing continuous perfusion of blood, comprising a guidewire having proximal and distal markers, a filter delivery and deployment system, having an outer member and an inner member, and a filter removably attached near the distal end of the inner member. The filter comprises proximal and distal basket sleeves which position the filter between the proximal and distal markers on the guidewire, after the guidewire is in position past the vessel occlusion. The guidewire placement prior to filter delivery may facilitate access to the interventional site, especially through tortuous anatomy. Also, retrievability of the filter from the wire may avoid loss of guidewire position, which may occur following removal of filters permanently attached to guidewires.
