“…The longest published implantation time prior to successful removal that we were able to identify for the Recovery filter is 735 days [18], although anecdotal reports of longer implantation to retrieval times have been made to the manufacturer, up to 975 days (Janet Hudnall, senior marketing manager for IVC filters, Bard Peripheral Vascular, personal communication). Prolonged retrieval times have also been reported for the Gunther Tulip filter (Cook) [12], although the longest we have found in the literature is only 475 days [24]. Although the Recovery filter is no longer available, we believe that the revised G2 filter should similarly allow for long retrieval intervals.…”
