Graft materials for surgical breast procedures

A method of making a graft implant, comprising:

• providing a sheet of biocompatible material;
• cutting a graft implant from the sheet of biocompatible material that is sized and shaped for conforming to a portion of a surface of a breast implant having a predetermined volume;
• and
• forming a set of perforations in the graft implant, the set of perforations including elongate slits arranged across at least a portion of the graft implant, wherein ends of longitudinally-neighboring elongate slits are arranged adjacent to each other;
• wherein, when the graft implant is in a planar configuration, the graft implant includes a first edge and a second edge, the first edge includes a convex portion that curves away from the second edge, and the second edge includes a convex portion that curves away from the first edge;
• wherein the convex portion of the first edge includes a first vertex and the convex portion of the second edge includes a second vertex;
• wherein the graft implant includes a longitudinal axis coincident with the graft implant and a vertical axis coincident with the graft implant, the vertical axis passing through the first and second vertices, and a distance along the longitudinal axis of the graft implant being longer than a distance along the vertical axis of the graft implant;
• wherein the vertical axis and the longitudinal axis are orthogonal to each other;
• wherein the convex portion of the first edge has a first radius of curvature and the convex portion of the second edge has a second radius of curvature, the first radius of curvature being different from the second radius of curvature;
• wherein the graft implant is symmetrical about the vertical axis;
• wherein the sheet of biocompatible material comprises an acellular tissue matrix;
• and
• wherein the set of perforations forms an arcuate pattern when the graft implant is in the planar configuration.

A method of treating tissue, comprising:

• providing a sheet-like sample of biocompatible material;
• selecting a tissue site of interest;
• and
• applying the sample of biocompatible material to the tissue site of interest;
• wherein the sample of biocompatible material includes a first edge and a second edge;
• wherein, when the sample of biocompatible material is in a planar configuration, the first edge includes a convex portion that curves away from the second edge and the second edge includes a convex portion that curves away from the first edge;
• wherein the convex portion of the first edge includes a first vertex and the convex portion of the second edge includes a second vertex;
• wherein the sample of biocompatible material includes a longitudinal axis coincident with the sample of biocompatible material and a vertical axis coincident with the sample of biocompatible material, the vertical axis passing through the first and second vertices, and a distance along the longitudinal axis of the sample of biocompatible material being longer than a distance along the vertical axis of the sample of biocompatible material;
• wherein the vertical axis and the longitudinal axis are orthogonal to each other;
• wherein the convex portion of the first edge has a first radius of curvature and the convex portion of the second edge has a second radius of curvature, the first radius of curvature being different from the second radius of curvature;
• wherein the sample of biocompatible material is symmetrical about the vertical axis;
• wherein the sample of biocompatible material comprises an acellular tissue matrix;
• wherein the sample of biocompatible material has a set of perforations, the set of perforations including elongate slits arranged across at least a portion of the sample of biocompatible material, wherein ends of longitudinally-neighboring elongate slits are arranged adjacent to each other;
• and
• wherein the set of perforations forms an arcuate pattern extending along the longitudinal axis when the sheet-like sample of biocompatible material is in the planar configuration.
