Title:
POROUS PLATE FOR MEDICAL APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2013/129465
Kind Code:
A1
Abstract:
Provided is a porous plate for medical applications, which is free of problems inherent in conventional barrier membranes, i.e., thicknesses and proliferation of bacteria, is thin, and has fine through-holes formed therein at a high density. The porous plate according to the present invention is a porous plate for medical applications, in which multiple through-holes are formed in a thin-plate-like base. The through-holes in the porous plate are formed by irradiating the base with laser light having a pulse width that is determined on the basis of a thermal diffusion length in the base upon the irradiation with the laser light, and the sizes and the arrangement of the through-holes are as follows: the pore diameter of each of the through-holes is 1 to 50 μm in terms of a circle diameter, and the center-to-center distance between any adjacent two of the through-holes is 2 to 200 μm.
