ABSTRACT:
An intravascular filter includes at least one elongated support member configured to assume a retention configuration, such as a generally helical form about a central axis, and at least one flexible elongated filter member supported by the support member. The filter member is configured to assume a predefined filter form in such a manner as to form an obstacle to passage through the vessel, in a direction parallel to central axis, of particles having dimensions greater than the predefined value. The support member and the filter member are preferably prepared in a generally straight configuration to facilitate minimally invasive deployment.
