1. An implant comprising:
a proximal hub defining a lumen;
an expandable portion extending distally from the proximal hub, the expandable portion configured to define an open volume in an uncompressed state, the open volume in fluid communication with the lumen; and
an expansion member having a distal end portion coupled to the proximal hub and a proximal end portion coupled to a distal region of a delivery wire, the expansion member being biased to contract from a non-relaxed state toward a relaxed state and thereby move the distal region of the delivery wire distally toward the distal end portion of the expansion member, wherein the expansion member does not extend to a distal end of the implant, and
wherein at least a portion of the delivery wire is disposed within the lumen.
