FDA clears Cook's Celect vena cava filter:

The Celect vena cava filter developed by Bloomington, Indiana-based Cook Medical may now be optionally retrieved when clinically indicated, following 510(k) clearance from the US FDA covering the new indication. The Celect filter gained US market clearance for permanent placement in the US in 2007. The implanted metal device is intended to be placed in the vena cava to prevent recurrent pulmonary embolism. It captures hazardous blood clots caused by trauma, surgery or other medical conditions before they can reach the lungs, causing an embolism.
