Abstract
Abstract The invention provides a system and method for performing less-invasive surgical procedures within a body cavity. In a preferred embodiment, the invention provides a system and method for isolating a surgical site such as an anastomosis between an internal mammary artery and a coronary artery in a thoracoscopic coronary artery bypass grafting procedure. The system comprises a foot ( 11 ) pivotally coupled to the distal end of a shaft ( 3 ) by a linkage ( 13 ). The foot has first and second engaging portions ( 15, 17 ) with contact surfaces for engaging a tissue surface. The engaging portions are movable between an open position, where the contact surfaces are separated by a gap, and a collapsed position, where the foot is configured for delivery through the percutaneous penetration. An actuator, at the proximal end of the shaft, can be rotated to pivot the foot about a transverse axis so that the contact surfaces are oriented generally parallel to the surgical site to apply pressure to the tissue structure on both sides of the surgical site.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
A method of performing a procedure on a coronary artery on a heart in a body of a patient, comprising: providing a device comprising a shaft having a proximal and distal end, and a foot pivotally coupled to the shaft, the foot having contact surfaces; creating a surgical opening in a chest wall of a patient; passing the shaft through the surgical opening and into a body cavity; pivoting the foot until the contact surfaces are generally parallel to the surface of the heart; contacting the surface of the heart with the contact surfaces of the foot; clamping the device to a clamping fixture to fix the position of the device relative to the body cavity; and performing a procedure on the coronary artery.
Claim 2
Independent Claim
124 words
A method of performing a procedure on a coronary artery on a heart in a body of a patient, comprising: providing a device comprising a shaft having a proximal and distal end, and a foot pivotally coupled to the shaft, the foot having contact surfaces; creating a surgical opening in a chest wall of a patient; passing the shaft through the surgical opening and into a body cavity; pivoting the foot until the contact surfaces are generally parallel to the surface of the heart; contacting the surface of the heart with the contact surfaces of the foot; clamping the device to a clamping fixture to fix the position of the device relative to the body cavity; and performing a procedure on the coronary artery.
Claim 3
Dependent Claim
26 words
The method of claim 1 , comprising the step of repositioning the heart within the body cavity by retracting or rotating the heart with the device.
Claim 4
Dependent Claim
23 words
The method of claim 1 , comprising the step of repositioning the coronary artery to improve access or visibility of the surgical site.
Claim 5
Dependent Claim
22 words
The method of claim 3 , comprising the step of sewing a free end of a mammary artery to the coronary artery.
Claim 6
Dependent Claim
27 words
The method of claim 1 , wherein the contact surfaces of the foot stabilize the heart during the step of performing a procedure on the coronary artery.
Claim 7
Dependent Claim
31 words
The method of claim 1 , comprising the step of stabilizing the coronary artery to permit the surgeon to sew a free end of a mammary artery to the coronary artery.
Claim 8
Dependent Claim
25 words
The method of claim 1 , wherein the step of performing a procedure on the coronary artery is performed as a conventional open surgical procedure.
Claim 9
Dependent Claim
31 words
The method of claim 1 , wherein the opening is created by a thoracotomy and the step of performing a procedure on the coronary artery is performed as a thoracoscopic procedure.
Claim 10
Dependent Claim
22 words
The method of claim 1 , comprising the step of sewing a free end of a mammary artery to the coronary artery.
