1. A device for implanting in an eye, comprising:
- an expandable sheath formed of an elongate, tubular body having at least one expandable feature configured to form an expanded and a compact configuration, the at least one expandable feature including at least two longitudinal, non-intersecting struts each extending from a proximal collar to a distal collar, and wherein the at least one of the proximal collar and distal collar is adaptable to an ocular implant, wherein the implant includes a second elongate tubular body configured to be implanted in an eye and wherein at least one of the proximal collar and the distal collar is fixedly attached to the second tubular body of the device and the other of the proximal collar and the distal collar is movably attached to the second tubular body of the device such that the distal collar slides co-axially along a longitudinal axis of the second tubular body.
