Patent ID: 8663150

Claim:
A system comprising: a cannula having a side wall defining a passageway, the cannula having a curved distal portion extending between a distal end and a proximal portion along a radius of curvature, the cannula including an opening extending through the distal end and the side wall to form a trough portion, the opening fluidly communicating with the passageway; an ocular implant disposed inside the passageway defined by the cannula; and a delivery tool having a distal interlocking portion engaging a complementary interlocking portion of the ocular implant to form a mechanically interlocking connection when the interlocking portion of the delivery tool is proximal to the trough portion of the cannula, the delivery tool distal interlocking portion having a curved at-rest shape having a smaller radius of curvature than the radius of curvature of the cannula distal portion, the cannula side wall preventing the delivery tool distal interlocking portion from assuming its at-rest shape when the delivery tool distal interlocking portion is proximal to the trough portion of the cannula.
