  • Methods and systems for magnetically suspending tissue structures
    Patent number: 10492812
    Abstract: A system for magnetically suspending tissue includes a grasper placement tool, a tissue grasper, a magnetic coupling element, and a tether which secures the magnetic coupling element to the tissue grasper. The grasper placement tool is used to simultaneously introduce both the tissue grasper and the magnetic coupling element to a body cavity. The grasper then releases the magnetic coupling element and engages a target tissue structure. The tissue grasper is then detached from the placement tool and a conventional laparoscopic or other grasper is used to engage the magnetic coupling element to an external magnet.
    Type: Grant
