Patent number: 6899670Abstract: An organ manipulator including at least one suction member or adhesive disc mounted to a compliant joint, a flexible locking arm for mounting such suction member or compliant joint, and a method for retracting and suspending an organ in a retracted position using suction (or adhesive force) so that the organ is free to move normally (e.g., to beat or undergo other limited-amplitude motion) in at least the vertical direction during both steps. In preferred embodiments, a suction member exerts suction to retract a beating heart and suspend it in a retracted position during surgery. As the retracted heart beats, the compliant joint allows it to expand and contract freely (and otherwise move naturally) at least in the vertical direction so that hemodynamic function is not compromised. The suction member conforms or can be conformed to the organ anatomy, and its inner surface is preferably smooth and lined with absorbent material to improve traction without causing trauma to the organ.Type: GrantFiled: July 10, 2002Date of Patent: May 31, 2005Assignee: Origin Medsystems Inc.Inventors: Steven Peng, Larry Voss, David E. Hancock, Grace A. Carlson, John Davis, Albert K. Chin, Jaime S. Vargas

Patent number: 6849044Abstract: An organ-stabilizing element is covered with a layer of textile material such as cloth to enhance slip-free engagement with an organ such as a beating heart during surgery thereon. The organ-stabilizing element is supported on a stacked structure of successive ball elements and rings that can be selectively flexible or rigid in response to tensioning of a flexible cable within a central bore of the structure.Type: GrantFiled: January 15, 2002Date of Patent: February 1, 2005Inventors: Larry Voss, Steven Peng, David Hancock, Grace Carlson

Patent number: 6730020Abstract: A flexible locking arm for use in an organ manipulator apparatus. The flexible locking arm has a flexible state, used to position the organ manipulator as needed, and a fixed state for mounting the manipulator in a desired orientation. Even in the fixed state, the organ manipulator maintains a limited freedom of movement, to allow the organ held to continue to move substantially according to its natural motion during functioning. For example, in an embodiment where a suction member exerts suction to retract a beating heart and suspend it in a retracted position during surgery by setting the flexible arm to the fixed state, as the retracted heart beats, a complaint joint allows it to expand and contract freely (and otherwise move naturally) at least in the vertical direction so that hemodynamic function is not substantially compromised.Type: GrantFiled: December 22, 2000Date of Patent: May 4, 2004Assignee: Origin Medsystems Inc.Inventors: Steven Peng, Larry Voss, David E. Hancock, Grace A. Carlson, John W Davis, Albert K. Chin, Jaime S. Vargas
