This is an updated version of the recovery filter. This nitinol (nickel-titanium alloy) filter has a conical shape with 6 legs and 6 filter wires arranged in 2 offset layers. It has elastic fixation hooks designed to allow easier removal. Maximum caval diameter for insertion is 28mm and it...

This nitinol filter has a non-tilt spiral shape, designed to be self-centering. It is anchored by an oversized double ring platform rather than by hooks or struts. This requires that the filter be sized to the caval diameter.     'A brief history of inferior vena cava filters and...

This is a newer design, laser cut from a single piece of nitinol for greater strength.  It has a conical shape with 6 struts and a caudal hook. It is inserted via a 5F system, the smallest on the market. The dual insertion filter is introduced to the femoral or jugular via a 6.5 F delivery...

This is a conical filter with 6 legs, each attached to a flat side rail that lies against the cava wall. These act as vertical stabilizing struts. It is made of Phynox® wire (same alloy as Conichrome®).      'A brief history of inferior vena cava filters and analysis...
