The Celect filter is a newer retrievable filter approved by the FDA in 2008. It is based on the Günther Tulip filter. The new design is made of the same material, Conichrome. The Celect filter has 4 anchoring struts for fixation and 8 independent secondary struts to improve self-centering and clot trapping.

The deployment kit is similar to that for the Günther Tulip filter, and it is available for both the femoral and jugular approaches. The same Günther Tulip filter retrieval set is employed for retrieval from the jugular approach.

Initial studies suggest that the retrieval interval of the Celect filter can be extended, with higher rates of successful retrieval. [92, 93]

In 2009, in a group of patients with Günther Tulip and Celect filters placed by intravascular ultrasonography (IVUS), Rosenthal et al reported filter tilt in 15 of 50 (30%) for the Günther Tulip filter and 6 of 65 (9.2%) for the Celect filter at cavography before retrieval. [94] Sangwaiya et al reported successful retrieval in 14 of 15 patients (93.3%) in a group of 73 placements, with a mean indwell time of 84 days (range, 5-381 d). [95] Two (2.8%) patients developed new PE after filter placement, similar in incidence to previous reports, and penetration of filter legs or arms was seen in 4 (22.2%). Fracture and migration of filter component, filter thrombosis, and iliac vein thrombosis were seen in 1 patient each (5.5%). [95]

In the same year, in a multicenter experience in 95 patients with Celect filter placement, Lyon et al reported 56 (96.6%) of the filters were successfully retrieved out of 58 patients with a mean indwell time of 179 days (range, 5-466 d). [96] They observed filter tilt greater than 15° in 5 (8.6%) patients at deployment and 2 (3.4%) patients at retrieval. Strut penetration was observed in 21 (36%) patients but no IVC perforation; 20 of these were retrieved successfully. [96] No significant filter migration, filter fracture, or IVC occlusion was observed.
