Boston Scientific told customers on August 24 to remove every Imager II angiographic catheter from use and from sale. The tips contain reduced levels of stabilizing agents, which can let them degrade and detach. Two serious injuries had been reported as of July 16, with no deaths.
The FDA flagged the risk of a device fragment blocking blood flow, up to a life threatening embolism and organ failure. Boston Scientific is not fixing the product. A spokesperson said the company will discontinue commercialization, so the catheter will no longer be available for intravascular procedures.
A material specification took out an entire catalog line. Incoming inspection on a polymer additive rarely gets the scrutiny a sterilization or software change does, and this is the failure mode it exists to catch.
