Wirion designed the device to hold and remove blood clots or other debris from a patient’s lower limbs. It was typically used during an atherectomy procedure.
What Is an Atherectomy?
Stanford Healthcare explains that an atherectomy is a procedure used to remove plaque from an artery or blood vessel. Removing plaque widens the artery, which allows blood to flow more freely to the heart muscles. A surgeon shaves or vaporizes plaque in the procedure, using tiny rotating blades or a laser on the end of a thin, flexible tube called a catheter.
An Atherectomy is used to treat peripheral artery disease and coronary artery disease. The procedure is sometimes performed on patients with very hard plaque, or on those who have already had angioplasty and stents implanted, but who still have plaque blocking blood flow.
Wirion stated in the recall: “Under certain circumstances, such as when the filter basket is too full, the filter assembly may become difficult to withdraw. In this situation, withdrawal may cause the WIRION system filter component to tear or separate, which may result in series (sic) adverse events such as embolization, need for additional medical procedures, or possibly death.”
