What is it indicated for?
The PleuraFlow System is indicated for use during cardiothoracic surgical procedures and chest trauma. Its active clearance technology proactively removes clots formed inside the chest tube to prevent or minimize chest tube occlusion with clot. A patent chest tube enables evacuation of blood and fluid from the operative site after closure of the surgical wound and reduces retained blood. The product is indicated for adult and pediatric patients including infant, preadolescent and adolescent patients under clinical settings.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
