STERILE AUTOLOGIC, ALLOGEN OR XENOGENIC IMPLANT AND METHOD FOR ITS MANUFACTURE

摘要

1. A cell-free sterile practically dehydrated and at least partially denatured matrix obtained from animal tissue and containing mainly collagen, the fibrils of which have the same structural organization as in the original tissue, intended for use as a temporary implant in medicine and veterinary medicine, characterized by the fact that it undergoes anisotropic changes in its measurements during hydration. ! 2. The cell-free matrix according to claim 1, characterized in that during the anisotropic change of its measurements during hydration, the two largest measurements remain practically unchanged or decrease, while the smallest measurement increases with an increase in the volume of the matrix. ! 3. The cell-free matrix according to claim 2, characterized in that the temporary implant has a predominantly flat shape, and its supporting surface is determined by its two largest dimensions, while its thickness is determined by its smallest dimension. ! 4. The cell-free matrix according to claim 1, characterized in that during hydration, the two smallest measurements increase, while the largest measurement remains practically unchanged or decreases. ! 5. The cell-free matrix according to claim 4, characterized in that the temporary implant has a predominantly oblong shape, such as a bar or cylinder, the cross-section of which is determined by the two smallest measurements, such as, for example, diameter, while its length or height is determined the largest dimension. ! 6. The cell-free matrix according to claim 1, characterized in that the matrix in a dehydrated state has a porosity of
