Abiomed Inc.‘s latest heart pump models got the nod to hit the market from the federal Food & Drug Administration.

The federal watchdog agency granted 510(k) approval for the Danvers-based heart pump maker’s Impella 5.0 and Impella LD devices.

That means the minimally-invasive catheter-based pumps are cleared to provide circulatory support for up to six hours, easing the burden on patients’ hearts during serious cardiac events.
