Cardica said that the design of the PAS-Port system allows a surgeon to load the bypass graft into the system and rapidly complete the anastomosis, typically in approximately two minutes, with little or no injury to the bypass graft vessel or the aorta.

The study, published in the November 2010 issue of the Annals of Thoracic Surgery, evaluated the frequency of major adverse events five years after undergoing coronary artery bypass graft (CABG) surgery using the PAS-Port system and patency (openness) of the grafted vessels six months following the procedure.

The results of the study show that the PAS-Port system produced a patent connection in 88% of the 117 vein grafts attached to the aorta using the PAS-Port system six months after surgery, as determined by angiography.

The PAS-Port system received 510(k) clearance from the US Food and Drug Administration in September 2008 and the CE mark in 2004.
