  • Publication number: 20260151221
    Abstract: Diversified grafts suitable for use in repair and reconstruction procedures are provided. Some diversified grafts comprise two or more heterogenous features which form regions having different preferred properties. A diversified graft useful for pre-pectoral breast reconstruction, meshing is provided on an upper pole of the diversified graft and a plurality of slits arranged in particular patterns is provided on a lower pole of the graft, whereby the upper pole has a greater expansion ability and the lower pole has lesser degree of expansion ability but maintains greater load bearing capacity which is necessary to support the lower pole of the breast undergoing reconstruction, while allowing for fluid egress. In other embodiments, the diversified graft comprises two or more components which are combined by attaching them to each other to form a larger graft of the required size. The components may be smaller pieces of the same material or different materials.

  • Publication number: 20260144914
    Abstract: Methods are provided for aesthetic restoration and reconstruction of bone loss, deficit, defect, or a combination thereof. The methods include administration of one or more suitable bone derived compositions by a minimally invasive procedure such as injection using a needle, syringe, etc., placement in or through a small incision, or a combination thereof. The properties and characteristics of the bone derived composition, including without limitation, flowability, injectability, size, shape, and physical form, are limited only by the requirement that they are capable of administration by a minimally invasive technique. For example, these methods are effective for restoration of facial features, e.g., lost chin definition, jawline definition, bone around nasal lines, and bone around the upper and lower eye area. These methods are also effective for treatment of bone deficiency and loss in other body features such as shoulders and collarbones, pelvis, feet, ankles, hands, and wrists.

  • Publication number: 20250352697
    Abstract: Improved allografts having controlled and consistent properties and useful for soft tissue repair, including breast reconstruction, and other surgical procedures, are disclosed. In one embodiment, an improved acellular dermal matrix (ADM) is produced from a skin sample, where the ADM consists essentially of a single dermal tissue type (e.g., papillary or reticular) and comprises a collagen matrix having substantially uniform density and porosity. In another embodiment, two ADMs are produced from the same dermal tissue type (e.g., papillary or reticular) of the same skin sample, each of which consists essentially of reticular dermis, and comprises a collagen matrix having substantially uniform density and porosity. All such improved ADMs are suitable for use in breast reconstruction and other tissue repair and modification surgery procedures.

  • Publication number: 20250099227
    Abstract: Volumizing grafts useful for plastic and reconstructive surgery, especially those involving replacement or enhancement of tissue mass and volume. The volumizing graft includes a sheet shaped body made of a biocompatible material which forms, or is capable of forming, a shape having a cavity for receiving, holding, containing, etc., one or more additional components. Either or both of the sheet shaped body and additional components may be bioactive. Either or both of the sheet shaped body and additional components may comprise tissue derived matrices. The sheet shaped body of the volumizing graft enables the additional components to be positioned, oriented, affixed, or some combination thereof, in or proximate to a treatment site, either permanently or temporarily. This may allow subsequent removal, repositioning, replacement, supplementing, or a combination thereof, of the additional components, at the treatment site.

  • Publication number: 20250058023
    Abstract: Shaped amalgamated cartilage grafts having predetermined three-dimensional shapes are provided which are formed from a plurality or population of cartilage derived pieces (e.g., particles, fibers, fragments, etc.) by any one or more manufacturing and processing techniques including additive manufacturing (e.g., 3-D printing), stereolithography, molding, casting, extrusion, molding or shaping followed by dehydration, and any 3-D formation technique capable of converting the plurality of cartilage derived pieces into a shaped amalgamated cartilage graft having a predetermined 3-D shape which is maintained after hydration of the graft. Additional processing techniques and material properties may contribute to or increase cohesiveness of the plurality of cartilage particles to hold or maintain the predetermined 3-D shape including, inherent or enhanced entanglement of elongated cartilage particles or fibers, curing, cross-linking (thermal, chemical, UV, etc.

  • Publication number: 20220062500
    Abstract: A ligament-derived graft is provided which comprises a portion of a ligament sample recovered from a mammalian donor and which has been cut approximately in half lengthwise, where the ligament derived graft has dimensions suitable for use in a surgical procedure to repair small to mid-sized, or less load bearing joints. Small joints for which the ligament-derived grafts may be used to repair, include, interphalangeal, metacarpophalangeal joint, scapholunate joint, and other joints. In some embodiments, the dimensions of the ligament-derived graft include a length of from about 50 mm to about 150 mm, and a width of from about 3 mm to about 20 mm. In some embodiments, ligament samples used to make the ligament-derived grafts are lateral or medial collateral ligaments. Methods of using such ligament-derived grafts include attaching one or more ligaments, at their ends, to bones on opposite sides of the joint being repaired, so that the ligament(s) extend across the joint.
