  • Patent number: 11723804
    Abstract: An apparatus is provided for draining aqueous humor from an eye for reducing intraocular pressure. The draining apparatus comprises a tube defining a passage for fluid flow between an inlet end and an outlet end. An outlet assembly contacts the conjunctival layer externally of the eyeball. The outlet assembly comprises a housing in fluid communication with the outlet end of the tube and having an aperture for allowing egress of aqueous humor onto the external ocular surface. A resistive component is disposed in the housing for providing resistance to a flow of aqueous humor. A pair of tabs project outwardly and are adapted to be disposed subconjunctivally for securing the draining apparatus relative to the eyeball.

  • 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.
