Document Type and Number:
WIPO Patent Application WO/2014/192803
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a tissue regeneration matrix which has excellent cell invasiveness and is suitable for regeneration of normal tissues. The present invention is a tissue regeneration matrix composed of a non-woven fabric composed of a bioabsorbable material manufactured by a melt blow method, wherein in a pore size distribution measured by a bubble point method, the non-woven fabric has a proportion of pores with a pore size of 5 to 30 μm of 70% or more, a proportion of pores that are less than 5 μm of 5% or less, and a proportion of pores that are greater than 30 μm of 10% or less, a median of a fiber diameter distribution of 0.5 to 8.0 μm and a coefficient of variation of 40% or more.
