Abstract: A system for reducing intraocular pressure of a patient in need including a delivery device and an intraocular implant positioned within the lumen of the cannula proximal to a retention plug. The delivery device has a housing sized to be held by an operator and an actuator. The delivery device has a cannula defining a lumen and having a proximal end coupled to the housing. The cannula extends along longitudinal axis from the proximal end to a distal end, the distal end of the cannula having rounded inner and outer edges defining a blunt, non-beveled distal opening from the lumen. The retention plug is attached to the cannula spanning the lumen near the distal opening. Related methods, implants and delivery tools are provided.

Abstract: A system for treating an eye of a patient in need including a delivery device having a housing sized to be held by an operator, an actuator and a distal nose cone; a needle coupled to and extending distal from the nose cone, the needle having a lumen and a beveled distal end defining a distal opening having a sharpened tip and heel proximal the distal opening; and a retention plug positioned within and spanning the lumen of the needle proximal to the heel; and an intraocular implant positioned within the lumen of the needle proximal to the retention plug. The retention plug is formed from a flowable retainer solution of hydroxypropyl methylcellulose (HPMC) in water having a concentration that is greater than 2.5% w:w and less than about 4% w:w. Related devices and methods are provided.
