Abstract:
The Recovery Cone Removal System was evaluated in vitro to determine its feasibility as an alterative retrieval device for the Günther tulip and OptEase inferior vena cava filters. The cone removal system was then used electively in eight patients to determine feasibility and safety in vivo and subsequently in a single patient when wire-snare removal failed. The Recovery Cone Removal System allowed in vitro and in vivo retrieval in all cases without difficulty or complication. The Recovery Cone Removal System offers an alternative to the wire-snare-based retrieval systems for removal of the Günther tulip and OptEase filters.
