This has a novel design with two nitinol spiral elements crimped at the ends to form a symmetric double-looped helical structure. A filter mesh designed to capture clots is attached to one loop.     'A brief history of inferior vena cava filters and analysis of current devices' -...

The TRAPEASE Permanent Vena Cava Filter from Cordis is designed for the treatment and prevention of recurrent pulmonary embolism. The filter is deployed via a 6F sheathed induction kit.  The updated temporary version is the OptEase filter.     'A brief history of inferior...

   This filter is made from 316L stainless steel alloy that is nonferromagnetic and is MR compatible. It has a dual level arrangement with 6 short hooked legs to ensure fixation to the caval wall and 3 longer legs for centering. It requires a 7F system for insertion. It is approved...

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...
