In short
Israeli device company Lumenis Limited is recalling certain models of VersaCut Morcellator devices because of the  potential for air embolisms to occur if the aspiration tubing is hooked up backwards to the aspiration control box housing. The FDA has decided that this product may cause serious adverse health consequences, including death, so has slapped a Class I status on the recall.
Background
Morcellators, as the name suggests, are devices that break up and remove dissected tissue during surgical procedures when access to the surgical site is limited, for example during laparoscopy.
