Device to permit offpump beating heart coronary bypass surgery
First Claim
1. A suction cup adapted to engage a surface of a beating heart with sufficient force to move the beating heart to an unnatural position upon moving the suction cup, while the suction cup maintains engagement with the surface of the heart and the heart continues to beat, said suction cup comprising:
- a first chamber having a flexible rim and configured to engage the surface of the beating heart; and
a second chamber smaller than said first chamber and fluidly connected therewith at a first end of said second chamber, and a suction line connected in fluid communication with said second chamber, wherein said second chamber provides a separation space between said first chamber and said suction line.

Abstract
A suction cup adapted to engage a surface of a beating heart with sufficient force to move the beating heart to an unnatural position upon moving the suction cup, while the suction cup maintains engagement with the surface of the heart and the heart continues to beat. Various suction cups are described each including at least a first chamber having a flexible rim and configured to engage the surface of the beating heart and a second chamber smaller than the first chamber and fluidly connected therewith. A suspension device configured to engage a beating heart and maintain engagement via suction while moving the suspension device to move the beating heart to an unnatural position and maintain the beating heart in the unnatural position to perform a surgical procedure, while the heart continues to beat, includes a suction cup and a support arm connected thereto. The suction cup has a first chamber configured to engage the surface of the beating heart, and a second chamber smaller than the first chamber and fluidly connected therewith. The second chamber is adapted to fluidly connect the first chamber with a source of suction. The support arm is movable with the suction cup to effect movement of the beating heart after engagement of the suction cup to a surface of the beating heart. A method of manipulating a beating heart to orient the beating heart in a desired position for performing a surgical procedure includes providing a suction cup having a first chamber configured to engage the surface of the beating heart, and a second chamber smaller than the first chamber and fluidly connected with the first chamber, the second chamber being further fluidly connected to a source of suction; contacting a surface of the beating heart with the first chamber; applying suction between the first chamber and the surface of the beating heart, thereby engaging the suction member with the surface of the beating heart; and moving the suction member while maintaining engagement with the surface of the beating heart, thereby moving the beating heart.

44. A method of manipulating a beating heart to orient the beating heart in a desired position for performing a surgical procedure, said method comprising the steps of:
-
providing a suction cup having a first chamber configured to engage the surface of the beating heart, and a second chamber smaller than the first chamber and fluidly connected with the first chamber at a first end of said second chamber, and a suction line connected in fluid communication with said second chamber, wherein said second chamber provides a separation space between said first chamber and said suction line the suction line being further fluidly connected to a source of suction; contacting a surface of the beating heart with the first chamber; applying suction between the first chamber and the surface of the beating heart, thereby engaging the suction member with the surface of the beating heart; and moving the suction member while maintaining engagement with the surface of the beating heart, thereby moving the beating heart. - View Dependent Claims (45, 46, 47)

48. A suspension device configured to engage a beating heart and maintain engagement via suction while moving the suspension device to move the beating heart to an unnatural position and maintain the beating heart in the unnatural position to perform a surgical procedure, while the heart continues to beat, said device comprising:
-
a suction cup having a first chamber configured to engage the surface of the beating heart, and a second chamber smaller than said first chamber and fluidly connected therewith, said second chamber being further adapted to fluidly connect said first chamber with a source of suction; and a support arm connected to said suction cup and movable therewith to effect movement of the beating heart after engagement of the suction cup to a surface of the beating heart, wherein said support arm is flexibly coupled to said suction cup, permitting multiplanar movement of said suction cup even after locking said support arm into said desired position.
