Abstract:
1. A method of manufacturing a shape memory material, comprising the steps of: a) providing a generally cylindrical substrate having an outer surface capable of accommodating metal deposition thereupon; b) vacuum depositing a metal onto the outer surface of the generally cylindrical substrate to form an unpatterned metal film on said outer surface of said generally cylindrical substrate, at least one of deposition chamber vacuum pressure, substrate temperature and bias voltage being controlled during the vacuum deposition to define a substantially homogeneous distribution of binding domains for endothelial cell attachment on the unpatterned metal film; c) defining a pattern of a plurality of openings passing through the deposited unpatterned metal film on the outer surface of the generally cylindrical substrate; and d) removing the generally cylindrical substrate from the patterned deposited metal film formed thereupon.
