A device includes an insertion member having a distal end portion configured to be removably engaged with an implant, and a sheath having an exit portion and defining a lumen. The exit portion of the sheath includes a set of dilation members configured to be moved from a first configuration to a second configuration. The set of dilation members forms a dilation surface when the set of dilation members is in the first configuration and defines an opening when the set of dilation members is in the second configuration. The sheath includes a hinge configured to facilitate movement of the set of dilation members between the first configuration and the second configuration. The distal end portion of the insertion member configured to move within the lumen to convey the implant from within the lumen via the opening when the set of dilation members is in the second configuration.
