  • Surgical instruments and procedures for stabilizing the beating heart during coronary artery bypass graft surgery
    Patent number: 7056287
    Abstract: Devices for stabilizing tissue during a surgical procedure. The beating heart may be stabilized during a surgical procedure on the heart, using a described stabilizing device. In one example, a stabilizing device is introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles id effectively eliminated such that the heart is stabilized and the site of the surgery moves only minimally if at all.
    Type: Grant

  • Surgical instruments and procedures for stabilizing the beating heart during coronary artery bypass graft surgery
    Patent number: 6394951
    Abstract: The invention is methods and devices which a surgeon may use to stabilize the beating heart during a surgical procedure on the heart. Pursuant to the invention, a stabilizing device is introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles is effectively eliminated such that the heart is stabilized and the site of the surgery moves only minimally if at all. Typically, in separate steps, the surgeon contacts the heart with the stabilizing device, assesses the degree of movement of the anastomosis site, and exerts a force on the stabilizing device such that the contraction of the beating heart causes only minimal excess motion at the surgery site.
