A specialist surgical tool used mostly in cardiovascular procedures, the Straight Shaft Debakey Patent Ductus Clamp is used to treat patent ductus arteriosus (PDA). When the ductus arteriosus, a blood channel that connects the aorta and pulmonary artery in a fetus, does not close after birth, it is known as a PDA. In order to obstruct the ductus and aid in its closure during surgery, this clamp is made to offer precise control.
