Abstract:
1. A device for treating a bone structure, comprising: a first biocompatible rigid or semi-rigid member having a proximal portion and a distal portion, the distal portion having a first plurality of ribs extending therefrom; a second biocompatible rigid or semi-rigid member having a proximal portion and a distal portion, the distal portion having a second plurality of ribs extending therefrom; wherein the first and second members have a combined cross-sectional circular profile, and each of the first and second members has a respective individual cross-sectional arcuate profile, the combined cross-sectional profile having a radius that is substantially equal to a radius of curvature of the individual cross-sectional profile, and wherein the device is configured to be placed in a collapsed state by engaging the first and second pluralities of ribs in an interposed arrangement with the respective proximal portions of the first and second members spaced apart from each other, and in a deployed state by disengaging the first and second pluralities of ribs, with the respective proximal portions of the first and second members moved towards each other.
