The Supreme Court made it harder for consumers to sue manufacturers of federally approved medical devices. In an 8-1 decision, the court ruled against the estate of a patient who suffered serious injuries when a catheter burst during a medical procedure. The case has significant implications for the $75 billion-a-year healthcare technology industry, whose products range from heart valves to toothbrushes. In a recent three-month span, federal regulators responded to over 100 safety problems regarding medical devices.
