New Optional IVC Filter for Percutaneous Retrieval - In Vitro Evaluation of Embolus Capturing Efficiency

Abstract

The new Celect filter showed similar in-vitro capture properties as the Gunther Tulip filter and deserves further in-vivo testing.

A design modification to minimize tilting of an inferior vena cava filter does not deliver a clinical benefit

“…In addition, the newer model has eight thin secondary wires designed to stabilize and selfcenter the filter. 1,13 The modified filter is also more expensive.…”

“…Excess tilting can be a barrier to filter retrieval and may compromise filtration efficacy and, theoretically, pulmonary embolism prophylaxis. [1][2][3][4][5][6] Use of both filters is well described in the literature. [7][8][9][10] Initial studies have analyzed the retrievability of the modified filter and have demonstrated excellent results with reported retrieval rates Ͼ90%, which compares favorably with the older standard model.…”

In vitro evaluation of clot capture efficiency of an absorbable vena cava filter

“…Some relied on only 10 trials for a single clot size; others combined trials from different setup parameters for each clot size, introducing variability not captured in the output statistic; others vary the number of trials without clearly defined justification. 21,24–27,30,31 Using such small numbers of trials especially with the smaller clot sizes creates large standard error for binomial distributions. Assigning the number of trials to achieve a standard error of 5% as performed in this study ensured adequate number of trials to yield high confidence in the statistical parameters.…”

Use of a retrievable inferior vena cava filter in term pregnancy: Case report and review of literature

“…In our patient we elected to use the Cook Celect™ IVC filter (Fig. 1), in preference to other retrievable filters because of its improved retrievability and comparable clot trapping ability 20–22 . It is a modification of the retrievable Gunther Tulip filter enabling for accurate centering of the filter within the IVC resulting in easier retrieval.…”
