Bioengineers have cleared a major hurdle on the path to 3-D printing replacement organs with a breakthrough technique for bioprinting tissues. The new innovation allows scientists to create exquisitely entangled vascular networks that mimic the body's natural passageways for blood, air, lymph and other vital fluids.

Concept Medical Inc. (CMI) has been granted Breakthrough Device Designation from the U.S. Food and Drug Administration (FDA) for MagicTouch, its sirolimus drug-coated balloon (DCB) catheter, for the treatment of coronary in-stent restenosis (ISR).

Abiomed announced that, on April 26, the U.S. Food and Drug Administration (FDA) approved initiation of the ST-Elevation Myocardial Infarction Door-to-Unloading (STEMI DTU) Pivotal Randomized Controlled Trial. The prospective, multi-center, two-arm trial plans to enroll 668 patients undergoing treatment for a STEMI heart attack. Half the patients will be randomized to receive delayed reperfusion after 30 minutes of left ventricular unloading with the Impella CP. The other half will receive immediate reperfusion, the current standard of care.
