What actions is Boston Scientific taking to address the premature battery depletion issues in its cardiac devices?
Boston Scientific Faces FDA Scrutiny over Heart Device Issues
Recent FDA Warnings & Device recalls
Boston Scientific, a leading medical device manufacturer, is currently under increased scrutiny from the Food and Drug administration (FDA) regarding potential issues with several of its cardiac devices. This FDA investigation centers around reports of premature battery depletion and device malfunctions,impacting patients relying on these devices for critical heart rhythm management. The concerns primarily revolve around implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds).
Specific Devices Affected
The FDA’s concerns aren’t blanket; they target specific models. Currently, the focus includes:
EnduraLife™ V+IQ ICD and CRT-D Systems: Reports indicate a higher-than-expected rate of battery failures in certain lots manufactured before October 2023.
AmpliA™ CRT-D Systems: Similar battery depletion issues have been reported with this device line.
Certain LOTs of Emagen™ ICD and CRT-D Systems: while less widespread, specific manufacturing lots of the Emagen system are also under review.
Patients with these devices are understandably anxious,and the FDA is urging vigilance. A full list of affected lot numbers can be found on the FDA website (https://www.fda.gov/). Regular monitoring by cardiologists is crucial.
