Abstract
A composite graft is disclosed, that may replace a segment of the hip labrum during a labral tear reconstruction. The composite graft may include a first sheet that acts as a scaffold and a second sheet that comprises a biologically active component. The first and second sheet are formed in a tubular roll with a spiraled cross section, with alternating layers of the first and second sheet. The composite graft may provide structural integrity for the hip labrum supplemented with growth factors.
Claims22
A hip labrum graft comprising:
- a first sheet comprising a scaffold component;
- and
- a second sheet comprising a biologically active component,
- wherein the first and second sheet are rolled together to form the hip labrum graft into a tubular rod with a spiraled cross section, defining alternating layers of the first and second sheet, and
- wherein the first sheet defines an outer-most circumferential surface of the tubular rod.
9-16. (canceled)
A composite graft comprising:
- a first sheet comprising fascia tissue;
- and
- a second sheet comprising placental tissue;
- wherein the first and second sheet are rolled together to form the composite graft into a tube with a spiraled cross section, defining alternating layers of the first and second sheet, with the first sheet defining an outermost layer of the alternating layers.
A method of adding a biologically active component to a tissue graft comprising:
- disposing a layer of the biologically active component on a planar surface of a tissue graft;
- rolling the tissue graft with the biologically active component disposed thereon into a tube with a spiral cross section, with alternating layers of the tissue graft and biologically active component, the rolling in a direction that defines the tissue graft as an external-most layer of the alternating layers.
