摘要:
A cannula for an ocular implant delivery system. In some embodiments, the cannula includes a tubular member having a curved portion, a distal opening surrounded by a distal opening surface, and a distal tip, the distal tip being adapted to be inserted into an anterior chamber of a human subjects eye, through trabecular meshwork and into Schlemms canal of the eye, a proximal portion of the tubular member being adapted to extend from a location exterior to the eye when the distal tip is in Schlemms canal of the eye, the cannula being further adapted to cooperate with an advancement mechanism to advance an ocular implant through the tubular member toward and through the distal opening into Schlemms canal of the eye when the distal tip is disposed in Schlemms canal. The invention also includes a method of deploying an ocular implant into Schlemms canal of a human eye including the following steps: inserting a distal tip of a delivery tool within an anterior chamber of the eye through trabecular meshwork of the eye into Schlemms canal of the eye and advancing an ocular implant through a curved portion and a distal opening of the delivery tool to place a body portion of the ocular implant in Schlemms canal and an inlet portion of the ocular implant in the anterior chamber.
