A system comprising:
a cannula (108) having a side wall (183,184) defining a passageway, the cannula having a curved distal portion (185) extending between a distal end and a proximal portion along a radius of curvature, the cannula including an opening (132); the opening fluidly communicating with the passageway; an ocular implant (150) disposed inside the passageway defined by the cannula; and
a delivery tool (152) having a distal interlocking portion (160) engaging a complementary interlocking portion (162) of the ocular implant to form a mechanically interlocking connection; the opening extending through the distal end and the side wall to form a trough portion (189); and the mechanically interlocking connection forming 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 portionfrom assuming its at-rest shape when the delivery tool distal interlocking portion is proximal to the trough portion of the cannula. |
