Displacement control wire device and method

A surgical control wire comprising:

• a control wire configured to provide curvature to displace a section of the esophagus of a human away from the heart during surgery, said control wire being formed of a shape memory material, said control wire having a spring temper and a suitable diameter to provide deflection of said esophagus, said control wire including a first end portion that is constructed and arranged to contact a first inner side wall of said esophagus, said first end portion including a distal end, said distal end including a stabilizer member, said stabilizer member being rounded having a surface area greater than said control wire, said stabilizer member constructed and arranged to prevent said control wire from puncturing said first inner side wall, said control wire having a first straight section adjacent said stabilizer member, an operative portion including a first bend and a second straight section in said control wire, said first bend and said second straight section configured to be large enough to force displacement of an opposite side wall of said esophagus in an opposite direction with respect to said stabilizer member, an offset bend for directing said control wire back toward a longitudinal axis of said first straight section, a second bend sized so that a shaft portion of said control wire is substantially axially aligned with said first end portion of said control wire, and a second end portion having a handle member for manipulation of said control wire, whereby rotation of said control wire mechanically displaces said section of said esophagus in the area of said esophagus containing said bends in said control wire.
