Abstract: A method for fabricating a microarray of plural soft materials includes: vapor-depositing a first layer poly(para-xylylene) resin on a substrate, forming a first micro pattern in the poly(para-xylylene) resin; obtaining a substrate including a first microarray formed by pouring a first soft material solution, freeze-drying the first soft material to obtain a micro-arrayed substrate of the freeze-dried first soft material; vapor-depositing a second layer poly(para-xylylene) resin on the micro-arrayed substrate of the freeze-dried first soft material, forming a second micro pattern placed differently from the first micro pattern by penetrating the poly(para-xylylene) resin of the first and second layers, forming a second microarray on the substrate by pouring a second soft material solution; and forming a microarray of the first and second soft materials on the substrate by peeling off the poly(para-xylylene) resin of the first and second layers.

Abstract: There is provided a method of preparing organic-solvent-free artificial lipid membranes formed over microapertures of a substrate and a substrate for holding the artificial lipid membranes. The method of preparing artificial lipid membranes over microapertures of a substrate includes forming a lipid pattern 5 on the perimeter of microapertures 4 formed in a substrate 1, swelling the lipid pattern 5 by an electroformation method, fusing the swelled lipid pattern, and further swelling the fused lipid pattern for each microaperture to prepare dome-shaped organic-solvent-free lipid membranes 7.

Abstract: A stent 1 comprises a sheet 2 of biocompatible material having a tubular shape and folded with a pattern of folds allowing the sheet 2 to be collapsed for deployment. The pattern of folds comprises a unit cell repeated over the sheet 2. A variety of different unit cells 3 are described. The pattern of folds may progress helically around the tubular shape of the sheet 2 which assists in implantation by synchronising deployment. The stent 1 further comprises a frame extending around the tubular shape of the sheet 2 and reinforcing the sheet 2. The frame comprises a plurality of elongate members arranged to fold relative to each other in conformity with the sheet 2 to allow the frame to be collapsed with the sheet 2 for deployment of the stent 1. The stent 1 prevents tissue in-growth because it is formed of a continuous sheet 2.

Abstract: A stent 1 comprising a sheet 2 of biocompatible material arranged as a tube and having a pattern of folds allowing the stent to be collapsed for deployment. The pattern of folds comprises a unit cell repeated over the sheet 2. A variety of different unit cells 3 are described. The pattern of folds may progress helically around the tube which assists in implantation by synchronising deployment. The stent 1 prevents restenosis because it is formed of a continuous sheet 2, and allows slippage to be minimised.
