REDWOOD CITY, Calif., May 5 /PRNewswire-FirstCall/ -- Cardica, Inc. (Nasdaq: CRDC) today announced that Husam H. Balkhy, M.D., chairman of the department of cardiothoracic surgery at The Wisconsin Heart Hospital in Milwaukee Wis., is one of the first cardiovascular surgeons in the United States to have performed several revolutionary closed-chest coronary artery bypass graft (CABG) procedures on a beating heart with the aid of the da Vinci(R) Surgical System. Applying his extensive experience with the C-Port(R) Flex A(R) Anastomosis System to robotic chest surgery, Dr. Balkhy has completed eight closed-chest beating heart CABG procedures on patients, all of whom were discharged an average of two days following surgery and were able to return to normal daily activities within two weeks.
During the procedure, Dr. Balkhy guides the da Vinci Surgical System to perform precise movements through fingertip-size incisions in the chest area, using a high definition camera and scope to facilitate visualization inside the chest. The off-pump, or "beating heart," bypass surgery is performed robotically without cutting the sternum and without the use of a traditional heart-lung machine.
"With the availability of the C-Port Flex A system and the recent introduction in the United States of Intuitive Surgical's EndoWrist(R) Stabilizer, we are seeing a convergence of technology that I expect will change the future of coronary bypass procedures and provide significant benefit to patients," said Dr. Balkhy.
"Multiple studies have shown that beating heart coronary bypass surgery has several benefits over traditional arrested heart coronary bypass surgery, in which the heart-lung machine is used. We have incorporated the beating heart approach in our practice for many years. I believe the newfound ability to 'spare the sternum' and perform bypass surgery using an all-port approach on the beating heart, with innovations such as the C-Port Flex A system and the da Vinci Surgical System, will further shorten recovery times and improve patient outcomes. As more surgeons become proficient performing this surgery, I believe that coronary bypass surgery may ultimately become a procedure requiring a relatively short hospital stay, a quicker return to activity and excellent outcomes for the majority of patients."
The C-Port Flex A system automates the attachment of the bypass graft to the coronary artery, eliminating the need to sew the graft using traditional suture and thread. "Just as a sewing machine can improve the reproducibility and speed of clothing production, I believe that this automated stapling device offers similar benefits by improving the reproducibility and speed of attaching the graft vessel during CABG surgery," added Dr. Balkhy, who has used the C-Port Flex A system more often than any other cardiovascular surgeon in the United States.
"These landmark procedures represent a significant advance for the field of cardiothoracic surgery. While the theory of beating heart robotic cardiac bypass surgery has been around for many years, the availability of the C-Port Flex A system is helping to enable robotic surgery on a beating heart to become a reality in cardiac surgery," said Bernard A. Hausen, M.D., Ph.D., president and chief executive officer of Cardica. "The C-Port Flex A device improves quality, reliability and consistency of bypass graft connections and can connect grafts at the back of the heart where it would be difficult or impossible to hand sew."
New Alternatives to Traditional Coronary Artery Bypass Surgery
In the majority of CABG procedures in the United States, the patient's sternum is split so the chest can be opened, and the heart is stopped temporarily while surgeons hand sew vessels together to bypass the blockages while a mechanical pump keeps the blood circulating through the body. Patients who receive on-pump CABG procedures stay in the hospital an average of five to seven days, and it can take up to two to three months for the patient to return to normal activity.
During a traditional "beating heart" bypass procedure, the patient's sternum is split, but the patient's heart continues to beat while a surgeon stabilizes the area of the heart to be bypassed. Eliminating the use of the heart-lung machine has been shown to reduce complications such as stroke, increased need for blood transfusions, and kidney and lung complications.
By using the robot together with the C-Port Flex A system, the beating heart procedure can be performed on a closed chest. Patients undergoing closed-chest CABG procedures may be discharged in 24 to 48 hours following surgery, and often return to normal activity levels within one to two weeks.
