Suction support and method of use
First Claim
1. A suction support for providing countertraction to a body tissue during surgery, comprising:
- an elongate tubular member having a proximal end, a distal end, and a lumen therebetween, wherein the tubular member carries a retractable surgical blade at its distal end, the retractable surgical blade being adapted to make an incision in the body tissue, and thereafter retract to avoid further cutting of tissue;
an arcuate member joined to the distal end of the tubular member, the arcuate member having a lumen which communicates with the lumen of the elongate member; and
at least one suction port disposed along the arcuate member and communicating with the lumen of the arcuate member.

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.

15. A suction support for providing countertraction to a body tissue during surgery, comprising
an elongate tubular member having a proximal end, a distal end, and a lumen therebetween; - wherein the tubular member carries a retractable surgical blade at its distal end, the retractable blade being adapted to make an incision in the body tissue and thereafter retract to avoid cutting of the body tissue;
an arcuate member joined to the distal end of the tubular member, the arcuate member having a lumen which communicates with the lumen of the elongate member; at least one suction port disposed along the arcuate member and communicating with the lumen of the arcuate member; and a plurality of suction cups disposed along the arcuate member, each suction cup communicating with a suction port. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
- wherein the tubular member carries a retractable surgical blade at its distal end, the retractable blade being adapted to make an incision in the body tissue and thereafter retract to avoid cutting of the body tissue;
-
28. A method for stabilizing a body tissue during surgery, comprising the steps of:
-
providing a suction support comprising an elongate tubular member having a proximal end, a distal end and a lumen wherein the tubular member carries a retractable surgical blade at its distal end, the retractable blade being adapted to make an incision in the body tissue and thereafter retract to avoid cutting of tissue; and
an arcuate member having at least one suction port and joined to a distal end of the tubular member;introducing the suction support into a patient'"'"'s thoracic cavity through an incision; positioning the suction support about a body tissue; applying a vacuum to the lumen of the elongate tubular member, wherein the body tissue is releasably engaged by the suction port; and removing the vacuum to thereby release the body tissue from the suction port. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
