Catheter-based Clot Images

These sample images are from patients successfully treated with catheter-based Intra-arterial thrombolysis (IAT).

These blood clots were removed by a catheter. The catheter in this procedure, called Merci Retriever, is made by Concentric Medical. This catheter was given approval by the FDA in August 2005. This approval gave Concentric Medical authorization to develop its Merci Retriever structure, which helps do away with blood clots in patients' brains who are having an ischemic stroke.

For more information and a viewable web video on catheter-based blood clot removal, please visit Concentric Medical Merci Retriever.
