Specific lots of reprocessed electrophysiology and ultrasound catheters may contain small residual particulates. If devices with residual particulates on patient-contacting surfaces are used, there is a potential risk of an inflammatory response or systemic infection, and if particulate were to dislodge during use and contact circulating blood and/or the heart, it may produce a granulomatous reaction or thrombus formation, which may lead to cerebral or pulmonary embolism, or deep vein thrombosis.
