Abstract:
1. A device for reinforcing a femoral neck bone, the femoral neck bone including a cortical bone region and a cancellous bone region, the device comprising: a unitary support structure deployable from a first substantially collapsed position to a second substantially expanded position, the unitary support structure having an outer surface and including, a head portion, a distal neck portion, a proximal neck portion, and a rigid fastener disposed on the outer surface of the unitary support structure that physically couples with at least a portion of the internal cortical bone region when the support structure is deployed in the second substantially expanded position; the unitary support structure having a generally hourglass-shape when deployed in the second substantially expanded position, the general hourglass-shape resembling a cortical bone inner surface shape—wherein the support structure is adapted to displace at least a portion of the cancellous bone region and support the femoral neck bone, the displaced cancellous bone region forming a void within the femoral neck bone; the unitary support structure formed at least partially from a material that increases its rigidity after a period of time and further secures the unitary support structure in the void within the femoral neck; the device further including an actuator adapted to create a bore at the Ward's triangle; create at least one cavity in a cancellous bone region of the femoral neck; insert the unitary support structure through the bore at the Ward's triangle and into the at least one cavity; expand the support structure; and allow at least a portion of the load from the femoral neck bone to be transferred to the unitary support structure, wherein the unitary support structure further comprises, an inflatable member adapted to expand the unitary support structure from the first substantially collapsed position to the second substantially expanded position, wherein the unitary support structure comprises a stent, the stent including at least one or more compression springs.
