Permanent or temporary IVC filtration with a novel double-ring anchoring technology optional nitinol filter

Abstract

Permanent or temporary implantation of inferior vena cava filters for protection against pulmonary embolism is well established. There have been numerous devices developed for this purpose, each of which has proprietary design considerations that affect performance and potentially impose limitations with regard to positioning, efficacy and risk profile. This article describes a recently developed, unique inferior vena cava filter design that employs a separated filtration component and a novel double-ring anchoring system that allows intraprocedural capture and repositioning for optimized placement. In addition, early experience suggests easy removal when desired, a high rate of filtration success and excellent caval patency.
