Abstract: The present invention provides a connective tissue body formation substrate which can form a film connective tissue having a desired thickness and both surfaces in a desired surface condition without prolonging the time required for formation of the connective tissue. Specifically, two tissue formation surfaces 2a and 2b are faced with each other with a tissue formation space 3 being interposed therebetween. A slit 9 is formed in the tissue formation surface 2b so that the tissue formation space 3 communicates with an outside of the substrate. A connective tissue body formation substrate 1 is installed in an environment where a biological tissue material is present. A connective tissue intrudes into the tissue formation space 3 from the slit 9. Both surfaces of the film connective tissue are formed so as to match the substrate surface.

Abstract: The present invention provides a connective tissue body formation substrate which can form a film-like connective tissue having a desired thickness and both surfaces in a desired surface condition without prolonging the time required for formation of the connective tissue. Specifically, two tissue formation surfaces 2a and 2b are faced with each other with a tissue formation space 3 being interposed therebetween. A slit 9 is formed in the tissue formation surface 2b so that the tissue formation space 3 communicates with an outside of the substrate. A connective tissue body formation substrate 1 is installed in an environment where a biological tissue material is present. A connective tissue intrudes into the tissue formation space 3 from the slit 9. Both surfaces of the film-like connective tissue are formed so as to match the substrate surface.

Abstract: The present invention provides a stent that can obtain sufficient strength while an inner side of the stent is easily endothelialized and moreover, can prevent occlusion of a branch blood vessel. Specifically, a stent body capable of diameter expansion is provided. A tubular film 3 is held by the stent body. In the tubular film 3, a plurality of communication holes 4 communicating between an inside and an outside are formed. Band-shaped portions 7 and 8 are formed between the communication holes 4 adjacent to each other. A wide-width portion and a narrow portion are not generated in the band-shaped portions 7 and 8. Strength of a part of the band-shaped portions 7 and 8 is not lowered. Generation of the wide-width portion in the band-shaped portions 7 and 8 is prevented.
