Abstract
The invention provides devices and methods for endoscopically cannulating the aorta, right atrium, and other body tissues to establish cardiopulmonary bypass for minimally invasive coronary artery bypass grafting surgery, and for other surgeries. After inserting the suction support through a minimal access port, the suction support having an arcuate member with suction ports provides countertraction to the aorta by creating a vacuum seal between its suction ports and the aorta, therefore facilitating aortic incision and cannulation. In one embodiment, the suction support allows aorta stabilization, incision, and insertion with an introducer to be achieved sequentially. Methods for using the devices herein are also disclosed.
