Claim Text:
1. A kit configured to form an expandable implant for treating bone, the kit comprising: a core element including a core body that defines a proximal end and a distal end spaced from the proximal end in a first direction, the core defining a core thickness along a second direction that is perpendicular to the first direction; and a plurality of expandable sleeves configured to be sequentially insertable over the core element in the first direction such that 1) a first expandable sleeve of the plurality of expandable sleeves overlies the core element with respect to the second direction and 2) a second expandable sleeve of the plurality of expandable sleeves overlies the first expandable sleeve with respect to the second direction and is configured to expand relative to the first expandable sleeve in the second direction as the expandable sleeves are sequentially inserted over the core element, wherein: each expandable sleeve has an interior surface that defines an internal bore and an exterior surface opposite the interior surface, each expandable sleeve defines a sleeve thickness from the interior surface to the exterior surface in the second direction, and each expandable sleeve is expandable in the second direction from an unexpanded configuration to an expanded configuration so as to cause a cross-sectional dimension of the internal bore to expand in the second direction without causing a change in the sleeve thickness.
