Abstract
This invention relates to an instrument for regenerating a living organism tissue or organ, characterized in that a support (A) formed from a biodegradable material or a bioabsorbable material includes a sponge-like fine matrix (B) formed from a biodegradable material or a bioabsorbable material and a linear guide channel (C) for a living organism tissue or organ.
Claims18
An instrument for regenerating a living organism tissue or organ, comprising a support (A) formed from a biodegradable material or a bioabsorbable material and, inside said support (A), a sponge-like fine matrix (B) formed from a biodegradable material or a bioabsorbable material and a linear channel (C) for guiding a living organism tissue or organ.
An instrument for regenerating a living organism tissue or organ, which comprises at least one linear structure (c) provided so as to penetrate a sponge layer (b) therethrough in a longitudinal direction in the inside of a tubular structure (a), wherein tubular structure (a) is formed by a bundle of collagen fibers with a fiber diameter of about 5 to 1,000 μm, having an outer diameter of about 0.1 to 50 mm, and an inner diameter of about 0.05 to 40 mm, and sponge layer (b) is a fine collagen sponge layer having a porosity of about 70 to 99.9% located inside the tubular structure.
