Abstract

The object of the present invention is to promote adequate body tissue formation action in a body tissue filling material. The present invention provides a graft material for body tissue regeneration 1 provided with a tubular member 2 composed of a material that allows nutrients B to permeate to the outside from blood A that passes therein, a body tissue filling material 3 arranged around the periphery of the tubular member 2, and a film 4 composed of a biocompatible material that covers them.

Claims

1. A graft material for body tissue regeneration comprising:

a tubular member composed of a material that allows at least either oxygen or nutrients to permeate to the outside from a liquid that passes therein, a body tissue filling material arranged around the periphery of the tubular member, and a film composed of a biocompatible material that covers them.

2. A graft material for body tissue regeneration according to claim 1, wherein the body tissue filling material is composed of a granular ceramic porous body, and the film is wrapped around and sutured to the body tissue filling material while leaving both ends of the tubular member exposed.

3. A graft material for body tissue regeneration comprising:

a calcium phosphate-based ceramic porous body arranged around the periphery of a blood vessel or artificial blood vessel, and a film composed of a biocompatible material that covers it.

4. A graft material for body tissue regeneration according to claim 3, wherein bone marrow and bone fragments are mixed into the ceramic porous body.

5. A graft material for body tissue regeneration according to claim 3 or 4, wherein a growth factor is mixed into the ceramic porous body.

6. A production method of a graft material for body tissue regeneration comprising:

arranging a body tissue filling material around the periphery of a tubular member composed of a material that allows at least either oxygen or nutrients to permeate to the outside from a liquid that passes therein, and covering the periphery of the body tissue filling material with a film composed of a biocompatible material.

7. A production method of a graft material for body tissue regeneration comprising:

arranging a calcium phosphate-based ceramic porous body around the periphery of a blood vessel or artificial blood vessel, and covering its periphery with a film composed of a biocompatible material.
