N1 - Funding Information:
A vena cava filter prototype (AngioDynamics, Queensbury, New York) was used in this study. This study was supported by AngioDynamics. The filter material is nitinol with a stainless steel hook for strength. The filter was laser-cut from two tubes of nitinol tubing, and the shape was heat-set. The filter is compatible with magnetic resonance imaging but was designed to have good visibility under fluoroscopy. The filter system allows for jugular and femoral delivery via a single delivery system by using a 6-F deployment catheter system. The filter has a self-centering design that was intended to cause a stable fixation within the IVC with minimal IVC wall damage upon retrieval.

N2 - An optional inferior vena cava (IVC) filter prototype was evaluated for safety and long-term retrievability as an initial feasibility study in an animal model. This filter has four centering struts that have the ability to disengage from the filtering cone portion, allowing the legs to slide out of endothelial growth. Retrieval of six filters in three animals was successful up to 27 weeks. There was no substantial filter tilt, migration, or IVC damage. In conclusion, this filter design may help overcome some of the shortcomings in currently approved optional IVC filters, including long-term retrieval difficulties, tilting, or migration.
