Cook Medical has worked with physicians since the mid-1980s to develop filter technologies designed to prevent PE in patients who are unable to receive anticoagulation medication. Cook currently offers two types of IVC filters that are able to be retrieved: the Celect Platinum® Vena Cava Filter and the Günther Tulip® Vena Cava Filter. Both filters are commonly referred to as “optional” filters; this means the filter may be removed when your doctor thinks that the danger of PE has passed or that you can effectively take anticoagulation medication. However, these filters can also remain within the body as permanent devices. Cook IVC filters have been implanted in hundreds of thousands of patients worldwide since they became commercially available, starting in 1997.
Your doctor may decide to place a Cook IVC filter if you have already had a PE, in order to prevent another one, in the following situations:
Both Cook optional IVC filters have an umbrella-like shape and are made of a cobalt chromium alloy, a special blend of metals. This design helps trap clots inside the top of the filter while still allowing blood to flow through the vena cava.
The Celect Platinum® and Günther Tulip® vena cava filters each have a tiny hook located at the top of the device, four primary legs with anchors (to keep the filter from moving), and a second set of stabilizing wires that also help to filter blood.

Celect Platinum retrieval
Cook Medical makes two devices to retrieve your Cook IVC filter. The CloverSnare® 4-Loop Vascular Retriever and the Günther Tulip® Vena Cava Filter Retrieval Set (GTRS) are both designed to capture the filter through a catheter placed into the jugular vein in your neck. If your doctor chooses to retrieve your filter, one of these devices may be used for that retrieval procedure.
Your doctor has a complete list of the risks related to these products.
Complications related to the Cook IVC filters fall into the same categories for both the Günther Tulip Vena Cava Filters and the Celect Platinum Vena Cava Filters:
In 2014, the FDA issued “Removing Retrievable Inferior Vena Cava Filters: FDA Safety Communication,” and in that communication, implanting physicians and clinicians responsible for the ongoing care of patients are encouraged to consider retrieving the filter once protection from PE is no longer needed.
