  • Tissue lifting devices and methods of use
    Patent number: 11311685
    Abstract: Various implementations include a tissue lifting device that is operable using one hand. The device includes a housing, an actuator that is slidably moveable through a channel within the housing, and a lifting mechanism adjacent a distal end of the housing. The actuator causes the lifting mechanism to lift a tissue. In some implementations, the housing includes a needle adjacent the distal end of the housing that punctures the tissue and allows for injection of a composition behind the tissue. The lifting mechanism according to some implementations is a suction-based (or aspiration) system. And, in other implementations, the lifting mechanism is a grasping system.
