Integral vascular filter system with core wire activation

摘要

A integral vascular filter system comprising a multi-filament guidewire and an integral filter which may be used to capture embolic particulates during medical procedures, while allowing for continuous perfusion of blood. Filter activation is achieved via the use of a central core wire. The vascular filter system addresses the clinical problem of minimizing profile or diameter, so as to enable or facilitate the crossing of a lesion or obstruction in the vessel.
