Allografts for soft tissue repair, including breast reconstruction and other plastic surgery procedures, are disclosed. One allograft is made from decellularized dermal tissue and constitutes a collagen matrix having substantially uniform density and porosity. Another allograft is a hybrid bilayer tissue form that is made from decellularized dermal and adipose tissues. Methods for making both allografts are also disclosed.

A tissue expansion device can be implanted temporarily beneath skin of a patient and removed upon expansion of overlying tissue. The device can include an expandable shell having a smooth or glossy outer surface and an injection port. The expandable shell can form an expandable chamber and have an anterior portion and a posterior portion. The injection port can be coupled to the anterior portion of the shell and be in fluid communication with the chamber and configured to permit injection of fluid into the chamber from a hypodermic needle. The device can have a plurality of tabs coupled to the posterior portion of the shell having one or more colors or attributes. The device can also include an orientation indicator visible along the anterior portion of the shell for assisting a clinician and orienting the device during the implantation procedure.

An artificial dermis repair material and a preparation method therefor. The artificial dermis repair material comprises a silicon rubber layer and a collagen complex layer adhered to each other; the collagen complex layer is prepared from raw materials comprising collagen, a mucopolysaccharide, and an antibacterial agent, which undergo a crosslinking reaction. The silicon rubber layer has high strength, high elasticity and softness, is easy to stitch, and has a good fitting performance; the collagen complex layer has good biocompatibility, degradability and an antibacterial property, and is suitable for repair and reconstruction of a dermal tissue.

A method of packaging amniotic membrane that maintains its structure to be used as a graft includes attaching the amniotic membrane to a support, dimensioning the amniotic membrane together with the support through an inert cutting device or guillotine, gluing the amniotic membrane together with the support to the interior of a container, and sterilizing the amniotic membrane. A packaged amniotic membrane includes a dimensioned sterilized amniotic membrane attached to a support, wherein the amniotic membrane is glued together with the support to a rigid, sterilized container.

In alternative embodiments, provided are compositions, e.g., pharmaceutical compositions, formulations, kits and other products of manufacture, comprising a hydrogel and active ingredients, including mixed thickness skin micrografts, or full or split-thickness skin grafts, contained or mixed in or within the hydrogel; and methods for making and using them. In alternative embodiments, compositions and methods as provided herein are used for the treatment or amelioration of wounds and surgical sites, and include compositions and methods for micrografting, or for micrografting a wound, or for micrografting a wound for rapid re-epithelialization, or for micrografting a wound for rapid re-epithelialization of large non-healing wounds.

The present disclosure relates to tissue matrix products. The products can includes tissue matrices that have holes or perforations located at certain positions to improve certain in vivo functions without substantial loss of strength or other important properties.

An artificial hair implant device is disclosed. The artificial hair implant device according to the present invention has: a body part having a hollow body; a head part in which a head is coupled and fixed to the body, an implant needle is provided to be able to enter and exit the head and has an artificial hair fitted around an end portion thereof that is drawn out from the head, and a return spring is provided between the implant needle and the head and returns the implant needle drawn out from the head back to an original position; and a button part in which a button is movably provided on the body, and a pressing shaft is provided under the button and enters and exits the body, thereby pressing the implant needle, such that the implant needle is drawn out from the head.

A hair implant suitable for subcutaneous implantation is provided having an anchor comprising an anchor body, and at least one collagen receiving structure selected from the group consisting of at least one tunnel disposed through the anchor body and an external surface feature of the anchor body. The anchor further comprises at least one hair strand projecting from a distal end of the anchor body, wherein the at least one collagen receiving structure is configured to support collagen ligature growth after subcutaneous implantation of the hair implant so as to anchor the anchor to a hair implant recipient, and the collagen receiving structure is free of hair.
