A hemostatic device, method of making, and method of using for internal and external applications to wounds in the body of a patient to induce homeostasis at an anatomical site.

The present invention provides an agent for treating ophthalmic diseases and a screening method for an agent for treating ophthalmic diseases and the like. The present invention also provides a method for predicting rejection associated with transplantation of retinal pigment epithelial cell to patients with ophthalmic diseases.

In accordance with the method of the present invention, 3D tissue-derived scaffolding materials are made in various formats, including but not limited to hydrogel, sponge, fibers, microspheres, and films, all of which function to better preserve natural extracellular matrix molecules and to mimic the natural tissue environment, thereby effectively guiding tissue regeneration. The method involves incorporating a homogenized tissue-derived suspension into a polymeric solution of synthetic, natural, or hybrid polymers to prepare tissue-derived scaffolds in the aforementioned formats. Such tissue-derived scaffolds and scaffolding materials have a variety of utilities, including: the creation of 3D tissue models such as skin, bone, liver, pancreas, lung, and so on; facilitation of studies on cell-matrix interactions; and the fabrication of implantable scaffolding materials for guided tissue formation in vivo. The tissue-derived scaffolds and scaffolding materials made in accordance with the present invention also provide the opportunity to correlate the functions of extracellular matrix with tissue regeneration and cancer metastasis, for example.

The present solution can temporarily impart the handling characteristics of corneal stroma to the otherwise very thin, flimsy, coiling, and fragile Descemet membrane endothelial keratoplasty (DMEK) tissue during its insertion into the anterior chamber and positioning in apposition against the cornea of the recipient eye. The device of the present solution can be configured in a number of ways. In a first configuration, a scaffold can be coupled with the endothelial side of the DMEK graft. In a second configuration, the scaffold can be coupled with the stromal side of the DMEK graft. In a third configuration, one or more scaffolds can be coupled with both the endothelial and stromal side of the DMEK graft.

The first object of the invention is a fibrin patch containing corneal limbal epithelial cells, characterized in that it contains a protein substrate, which is dried and rehydrated fibrin, a density of corneal limbal epithelial cells on the protein substrate is from 5,000 cells/cm2 to 70,000 cells/cm2, and the protein substrate does not contain a nutrient layer. The invention discloses also the method of the manufacturing of the patch.

This disclosure describes methods of preparing a decellularized Descemet's membrane and an isolated Descemet's membrane, methods of using an isolated Descemet's membrane, and tissues prepared using an isolated Descemet's membrane. This disclosure further describes a composition that includes an isolated Descemet's membrane. In some embodiments, the tissues and methods described herein may be used to treat a limbal stem cell deficiency or as an ocular surface bandage.

One method of isolating the Dua's layer includes separating the Descemet's membrane from the cornea using a hydrodissection technique, removing the Descemet's membrane from the cornea, and separating the Dua's layer from the cornea. A second method of isolating the Dua's layer includes simultaneously separating the Dua's layer from the stroma and separating the Dua's layer from the Descemet's membrane. A third method of isolating the Dua's layer includes dissecting the Dua's layer from the cornea using femtosecond laser. A fourth method of isolating the Dua's layer manually dissecting the Dua's layer from the cornea using forceps. The isolated Dua's layer can be preserved as either a fresh graft for up to 14 days or as a sterile graft for up to two years. Methods of using an isolated Dua's layer include on the ocular surface, mid-stroma, on the posterior cornea, and seeded with endothelial cells for corneal application.

The present disclosure provides devices and methods for treating breasts. The devices can include an acellular tissue matrix having a predefined shape that allows for complete or enhanced coverage of an anterior portion of a breast implant or tissue expander or to support an implant and/or surrounding tissues.

The present invention relates to a method for producing transplantable oral mucosa tissue by selecting and choosing from oral mucosa biopsy, and to the use thereof as pharmaceutical composition, medicament or transplant or graft material, in particular for urethral reconstruction or cornea implantation. In particular, the invention relates to markers for identifying suitable transplantable oral mucosa tissue for the production of transplantable oral mucosa tissue, in particular for producing an autologous oral mucosa graft or tissue.
