Read MoreHide Full Article

Inari Medical, Inc. (NARI - Free Report) has announced critical updates to the instructions for using its ClotTriever XL Catheter, 30mm, a device designed to remove clots from large blood vessels. This action follows a recall issued by the FDA, which was identified as the most serious type due to reported adverse events, including serious injuries and deaths. The recall focuses on updating usage guidelines to prevent life-threatening complications, such as device entrapment, vessel damage and a pulmonary emboli, but does not remove the product from the market.

Inari Medical launched the ClotTriever XL Catheter in April 2023. NARI has updated the instructions for its ClotTriever XL Catheter, adding critical warnings and procedural guidelines to enhance patient safety. These updates include specific instructions to avoid pulling the catheter through certain veins to prevent advancing clots into the heart or pulmonary arteries and consider the potential risk of pulmonary thromboembolism when removing clots from large vessels like the inferior vena cava. Additionally, the guidelines now recommend using a clot entrapment device to minimize the risk of embolization and advise against attempting to remove large clots in a single pass. 

Inari Medical has issued a voluntary field notice for the ClotTriever XL catheter, providing updated procedural guidance for physicians. This update, which is not related to any device defect, aims to enhance the use of ClotTriever XL for treating complex deep vein thrombosis (DVT) and is expected to have no impact on revenues.

Significance of Recall

This recall by Inari Medical is of high significance as it aims to address severe safety risks associated with the ClotTriever XL Catheter. The updated instructions are crucial for preventing serious health consequences, including potential death, particularly in patients with fibrous, adherent, or calcified clots, as well as those with suspected tumor thrombus and caution against the use of clot capture devices in the venous system. With four reported injuries and six deaths linked to improper usage, the FDA’s recommendations highlight the necessity for healthcare providers to strictly follow the revised guidelines. NARI is also ensuring that all relevant training materials are updated and healthcare providers are adequately informed to mitigate these risks.

More on the News

In response to the recall, Inari Medical sent an Urgent Medical Device Labeling Correction to all affected customers on Jul 19, 2024. The letter advises healthcare providers to review the new instructions, share them with relevant personnel and complete an acknowledgment form. NARI is also updating all related training materials to ensure that healthcare providers are fully informed of the risks and proper usage techniques, especially when dealing with complex clot scenarios.
