Boston Scientific Recalls Defective Stent System
Boston Scientific is recalling (Class 1) its Carotid Wallstent Monorail Endoprosthesis due to a manufacturing defect that created an inner lumen smaller than specifications, which causes resistance when withdrawing the stent delivery system. “Using the affected stent systems could cause serious harm, such as injury to the blood vessel, damage to the stent or release of debris that could travel to the brain and cause a stroke,” a recall notice says. To date, the notice says Boston Scientific has reported six cases that required additional intervention to recover the device.
The device is described by the notice as a self-expanding stent used to open narrowed carotid arteries and is placed using a catheter over a guidewire or embolic protection device.
