The ideal vena cava filter would trap venous emboli while maintaining normal venous flow. Many different filter configurations have been used, but the current benchmark remains the Greenfield filter with the longest long-term data. Patency rates greater than 95% and recurrent embolism rates of less than 5% have been demonstrated by numerous studies. The conical shape allows central filling of emboli while allowing blood on the periphery to flow freely. Numerous other filters with similar track records have since been developed, including filters that can be removed.
