Royal Philips (NYSE: PHG, AEX: PHIA), a global leader in health technology today announced the FDA has granted De Novo Clearance for Philips IVC Filter Removal Laser Sheath – CavaClear – to remove an IVC filter when previous methods of removal have failed. CavaClear is the first and only FDA-cleared solution for advanced IVC filter removal. Earlier in 2021, the FDA granted the device Breakthrough Device Designation. Laser has been clinically proven to provide a success rate over 99%, with low complication rates .
IVC filters are used to treat patients with venous thromboembolism, in which blood clots form in the deep veins of the leg and groin, and can travel through the circulatory system. They are placed in the inferior vena cava to capture blood clots from moving to the lungs. However, research has shown that IVC filters may have long-term complications . The filters can fracture and travel through the bloodstream to other parts of the body. Other identified long-term risks associated with IVC filters include lower limb deep vein thrombosis and IVC occlusion. The FDA recommends that implanting physicians consider removing retrievable IVC filters as soon as they are no longer indicated .
Failure rates for IVC filter removal can be high and prior to CavaClear, limited options for removal existed if the filter became difficult to remove. Advanced retrieval tools and techniques are required if the IVC filter becomes embedded in the vasculature. Physicians previously had very few tools to remove the filter when complications occurred and until now there were no FDA-approved devices for this type of advanced removal.
