1. An ocular implant system, comprising:

  • an ocular implant, the implant comprising an elongated body, the elongated body including;

    an inlet port arranged on a proximal end segment of the implant to communicate with an anterior chamber of an eye;

    an inner lumen communicating with the inlet port;

    a plurality of outlet ports located on a distal end portion of the ocular implant, the plurality of outlet ports being in communication with the inner lumen and configured to drain aqueous humor out of the anterior chamber of the eye; and

    one or more retention features arranged to contact ocular tissue;

    wherein the ocular implant comprises polyimide material; and

    wherein the ocular implant is tubular; and

    a delivery device comprising;

    an elongated member carrying the ocular implant and being configured for ab interno insertion of the ocular implant, the elongated member having a distal portion, the distal portion being curved at least when deployed in the eye for accessing a target tissue site in an anterior chamber angle within the eye with the elongated member extending through an opening into the anterior chamber of the eye disposed apart from the target tissue site; and

    a handpiece, wherein the handpiece comprises an actuator and a spring, the spring being disposed within the handpiece and being operably coupled to the actuator such that actuation of the actuator causes at least partial unloading of the spring when deploying the ocular implant,wherein both the curved distal portion of the elongated member and the inner lumen of the ocular implant have a circular cross-section, andwherein the curved distal portion of the elongated member is further configured to make an opening through ocular tissue at the target tissue site.
