ABSTRACT:
The filter is composed of two portions. A first portion is a set of zi-zag struts arranged in a cylindrical fashion which fit against the wall of the vascular lumen and provide a base for positioning a filter portion. A filter portion is a set of struts. Each filtering strut has its upstream end connected to the positioning portion at the vascular wall and its downstream end held at a central position in the vascular lumen by a frangible connector or cord.The central connector has a center opening to permit blood flow through the central opening. When the cord is cut, the resilient filter struts flex radially outward against the vascular wall in a parked condition to provide a non-filtered state without requiring removal of the filter from the patient.
