摘要:
Devices and procedures for assisting drainage of aqueous humor from the eye are provided. In accordance with some embodiments, an implant sized to fit within the Schlemms Canal is provided. The implant has a plurality of penetrating members having an unextended position in which the penetrating members lie generally close to the longitudinal axis of the implant and an extended position in which the penetrating members are extended outward. In use, the implant is advanced around at least a substantial portion of the Schlemms Canal with the penetrating members in the first unextended position. After the implant is positioned within the Schlemms Canal, the penetrating members are caused to move from the first unextended position to the second extended position, wherein the penetrating members penetrate the wall of the Schlemms Canal. This creates fluid passageways in the wall of the Schlemms Canal. The implant can also serve to keep the Schlemms Canal open. A delivery device is also provided for implanting an implant into the Schlemms Canal.
