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: 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.

Patent number: 6527786Abstract: The invention is directed to a medical device for endoscopically ligating and cutting a body vessel. The device may be percutaneously inserted into a patient to perform several possible procedures. The improvements to the device include a hinged jaw capable of grasping and crimping body vessels. An improved clip delivery system and an improved clip which ligate body vessels are also described. The instrument includes a rotating cutting member which provides more efficient body vessel cutting means. Furthermore, the entire system allows a simplified and more efficient method of operation.Type: GrantFiled: June 21, 1999Date of Patent: March 4, 2003Assignee: Origin Medsystems, Inc.Inventors: John W. Davis, David E. Hancock, Charles J. Adam

Patent number: 6306116Abstract: A method and apparatus for pressurizing the right atrium or right ventricle of a beating heart during surgery to assist cardiac function. The apparatus has an intake tube for insertion in the inferior or superior vena cava, a return tube for insertion in the right atrium or right ventricle, and a pump (e.g., a peristaltic pump). In operation, blood is pumped from the vena cava into an intake port of the intake tube, from the intake tube through the pump to the return tube, and from the return tube to the right atrium or right ventricle. Optionally, a balloon mounted around the intake tube's distal end is inflated to center the intake port in the vena cava and provide a pressure bulkhead. The pump preferably pumps blood in one direction from an input port to an output port.Type: GrantFiled: September 30, 1999Date of Patent: October 23, 2001Assignee: Origin Medsystems, Inc.Inventor: David E.
