Cardica’s Anastomosis Systems Enable ‘Total Connector’ Beating Heart Cardiac Bypass Procedures
WAUWATOSA, Wis. and REDWOOD CITY, Calif., Oct. 1 /PRNewswire-FirstCall/ — Nationally-renowned cardiothoracic surgeon Husam H. Balkhy, M.D., chairman of the department of cardiothoracic surgery at The Wisconsin Heart Hospital, performed the first total connector cardiac bypass procedure in the U.S., without needing to arrest the heart, using only Cardica’s automated systems to connect the bypass graft vessels. With the recent U.S. Food and Drug Administration clearance of the PAS-Port(R) Proximal Anastomosis System, Cardica now offers surgeons a comprehensive suite of products to quickly and reliably attach all grafts during coronary artery bypass graft (CABG) surgery. This will allow surgeons, for the first time, to achieve a total “connector coronary artery bypass” procedure, or C-CAB(TM), meaning the CABG procedure can be completed without the need to use hand-sewn sutures to connect the bypass graft vessels.
Cardica’s anastomosis systems automate the connection of blood vessels (known as anastomoses) during CABG surgery, replacing hand-sewn sutures, which are more time consuming and can be difficult to perform especially in small coronary arteries. Anastomoses are often considered the most critical step of the bypass procedure. Cardica’s PAS-Port proximal system attaches the bypass graft to the aorta, upstream of the occlusion, while Cardica’s C-Port(R) Distal Anastomosis Systems connect the bypass grafts to coronary arteries downstream of the occlusion. A triple bypass procedure, for example, requires up to five anastomoses. Now, in many instances, all connections could be performed using Cardica’s PAS-Port and C-Port anastomosis systems.
“By using Cardica’s automated systems, we were able to successfully attach all of the bypass vessels rapidly and consistently, even in areas of the heart that can be difficult to reach, while the patient’s heart continued to beat,” said Dr. Balkhy. “This was a relatively difficult case, complicated by the patient’s multi-vessel disease, small targets and diminished cardiac function. Performing a multiple bypass procedure using traditional techniques such as stopping the heart and placing the patient on a heart-lung machine, can be associated with significant risks. Using connectors such as these will help facilitate CABG surgery without the need to use a heart-lung machine.”
Dr. Balkhy and his team at The Wisconsin Heart Hospital performed the triple-bypass procedure on a 69-year-old female patient who had severe coronary artery disease, severe chronic obstructive pulmonary disease (COPD) and aortic plaque. This made a traditional CABG surgery particularly risky. The team completed the entire three-vessel, total-connector off-pump CABG surgery in 2.5 hours. The patient was discharged three days after surgery and is doing well today.
“Today, general surgeons extensively use miniature stapling devices for anastomoses in bowel, abdominal and even pulmonary surgical procedures, whereas 20 years ago hand-sewn sutures were used for virtually all of these procedures,” continued Dr. Balkhy. “Just as staplers have become the standard of care in general surgery, I believe that cardiothoracic surgeons in the United States and worldwide will eventually adopt automated stapling devices for anastomoses as the standard of care in cardiac bypass surgery.”
“We congratulate Dr. Balkhy on completing the first total connector CABG procedure in the United States and his continued commitment to the advancement of less-invasive cardiothoracic surgery. We are proud of the role Cardica’s products played in enabling this significant milestone,” said Bernard A. Hausen, M.D., Ph.D., president and chief executive officer of Cardica. “As we continue to train surgeons on the use and benefits of both our C-Port and PAS-Port systems, we expect many more surgeons to switch from hand sewing sutures to using our automated devices for traditional open-chest procedures, beating heart surgery and minimally-invasive robotic CABG procedures.”

About CABG Surgery
Coronary heart disease causes one out of every five deaths in the United States, making it the single largest killer of Americans. While other treatment alternatives exist, studies show that CABG surgery achieves the best long-term patient outcome for coronary heart disease as measured by survival rate and need for re-intervention. The National Center for Health Statistics estimates that in 2005 approximately 260,000 patients had CABG surgeries in the United States.
About Cardica’s Anastomosis Systems
Cardica’s automated anastomosis systems attach the end of a bypass vessel graft to a coronary artery or to the aorta. This connection, called an anastomosis, is often considered the most critical step of bypass surgery. The current method of performing an anastomosis takes approximately ten to 15 minutes per anastomosis and uses technically demanding, tedious and time-consuming hand-sewn sutures to connect a blood vessel to the aorta or to small diameter coronary vessels. Using Cardica’s automated systems, the connection can be completed typically in less than two minutes and requires no additional hand-sewn sutures for the anastomosis.
About The Wisconsin Heart Hospital
Located in Wauwatosa, Wisconsin, The Wisconsin Heart Hospital, a member of Wheaton Franciscan Healthcare, was the vision of a group of cardiac, vascular and specialty physicians who wanted to treat broad-based diseases that affect cardiac and vascular systems. They began with a unique premise — they wanted to help shape the future of cardiovascular care through locating innovative workflow, patient care, diagnostics and imaging technologies under one roof.
The only cardiovascular specialty hospital and first accredited chest pain center in the Milwaukee area, the hospital was designed for the complexities of heart and vascular care. Its services include diagnostic and interventional cardiac catheterization and peripheral vascular procedures, electrophysiology, surgical services, diagnostic imaging, and emergency services.
As a result of its focus on patient service, TWHH has earned numerous national awards for patient perception of quality and service. TWHH is in the top 1% of hospitals nationwide in patient satisfaction, according to Press Ganey, and has also met or exceeded state and national benchmarks in quality care. The hospital has repeatedly earned top honors in the nation for inpatient cardiology/telemetry.
