In 2005 Boston Scientific recalled its Enteryx device, an injectable treatment for acid reflux disease, after the death of an elderly woman three weeks after she underwent treatment. Reports of six injuries are also linked to the use of the Enteryx.

The Enteryx treatment, which the company had identified as one of its top products in terms of sales growth potential, involves the injection of a plastic substance into the esophagus to help protect patients from acid backing up from the stomach. In the case of the patient who died, some of the polymer had been injected into the woman's aorta, which ruptured, causing her to bleed to death.
