An ocular implant delivery system comprising a delivery device preloaded with an implant, wherein: the delivery device (210, 110) comprises: a generally elongated outer housing (222, 122) that is ergonomically contoured; an elongated insertion sleeve (344, 140) partially disposed in the outer housing (222, 122) and having a non-linear exposed distal portion (368, 164) extending out of a distal end of the housing (222, 122), wherein the non-linear exposed distal portion (368, 164) has a curvature adapted to facilitate ab interno suprachoroidal implantation; an obturator (244, 144) passing through a lumen of the insertion sleeve (344, 140) and having a non-linear distal portion extending beyond the non-linear distal portion of the insertion sleeve (344, 140), wherein, in use, the non-linear distal portion of the obturator (244, 144) is adapted to provide access to a suprachoroidal space through a ciliary muscle attachment, wherein the non-linear distal portion of the obturator (244, 144) is flexible and has a curvature adapted to maintain pressure against the sclera during insertion into the suprachoroidal space; and a trigger (248, 148) operatively coupled to the obturator (244, 144) such that movement of the trigger (248, 148) towards a proximal end of the housing (222, 122) retracts the obturator (244, 144) within the insertion sleeve (344, 140); and the implant (220, 120) is adapted to be disposed on the non-linear portion of the obturator (244, 144) and positioned distally of the non-linear distal portion of the insertion sleeve (344, 140) prior to insertion of the delivery device (210, 110) into an eye, wherein, in use, a distal end of the insertion sleeve (344, 140) is adapted to react against a proximal end of the implant (220, 120) as the obturator (244, 144) is being retracted to deliver the implant (220, 120). the delivery device (210, 110) comprises: a generally elongated outer housing (222, 122) that is ergonomically contoured; an elongated insertion sleeve (344, 140) partially disposed in the outer housing (222, 122) and having a non-linear exposed distal portion (368, 164) extending out of a distal end of the housing (222, 122), wherein the non-linear exposed distal portion (368, 164) has a curvature adapted to facilitate ab interno suprachoroidal implantation; an obturator (244, 144) passing through a lumen of the insertion sleeve (344, 140) and having a non-linear distal portion extending beyond the non-linear distal portion of the insertion sleeve (344, 140), wherein, in use, the non-linear distal portion of the obturator (244, 144) is adapted to provide access to a suprachoroidal space through a ciliary muscle attachment, wherein the non-linear distal portion of the obturator (244, 144) is flexible and has a curvature adapted to maintain pressure against the sclera during insertion into the suprachoroidal space; and a trigger (248, 148) operatively coupled to the obturator (244, 144) such that movement of the trigger (248, 148) towards a proximal end of the housing (222, 122) retracts the obturator (244, 144) within the insertion sleeve (344, 140); and a generally elongated outer housing (222, 122) that is ergonomically contoured; an elongated insertion sleeve (344, 140) partially disposed in the outer housing (222, 122) and having a non-linear exposed distal portion (368, 164) extending out of a distal end of the housing (222, 122), wherein the non-linear exposed distal portion (368, 164) has a curvature adapted to facilitate ab interno suprachoroidal implantation; an obturator (244, 144) passing through a lumen of the insertion sleeve (344, 140) and having a non-linear distal portion extending beyond the non-linear distal portion of the insertion sleeve (344, 140), wherein, in use, the non-linear distal portion of the obturator (244, 144) is adapted to provide access to a suprachoroidal space through a ciliary muscle attachment, wherein the non-linear distal portion of the obturator (244, 144) is flexible and has a curvature adapted to maintain pressure against the sclera during insertion into the suprachoroidal space; and a trigger (248, 148) operatively coupled to the obturator (244, 144) such that movement of the trigger (248, 148) towards a proximal end of the housing (222, 122) retracts the obturator (244, 144) within the insertion sleeve (344, 140); and the implant (220, 120) is adapted to be disposed on the non-linear portion of the obturator (244, 144) and positioned distally of the non-linear distal portion of the insertion sleeve (344, 140) prior to insertion of the delivery device (210, 110) into an eye, wherein, in use, a distal end of the insertion sleeve (344, 140) is adapted to react against a proximal end of the implant (220, 120) as the obturator (244, 144) is being retracted to deliver the implant (220, 120).
