The FDA recently approved a mini heart pump that can be placed in the left ventricle without open chest surgery.
The Impella 2.5 System draws blood out of the heart and pumps it into the aorta.
The device is mounted at the end of a catheter, the tip of which is inserted through an incision in a major artery in the leg. The catheter is then threaded through the patient’s arteries until the pump is positioned in the left ventricle. When in place, an external console drives it.
