Claim 0:
1. An absorbable polymer medical implant for contacting tissue comprising:
a substrate having an inner core and an outer surface, the outer surface comprising a first plurality of microfeatures disposed on top of a second plurality of microfeatures, at least one microfeature of the plurality of second microfeatures having a height of 50 to 200 microns and a width of 50 to 200 microns;
the substrate comprising a polymer that is degradable in vivo by hydrolysis or enzymatic degradation; and
wherein the first plurality of microfeatures is hydrophilic such that when exposed to an aqueous environment, the volume of the microstructure is hydrated, and wherein the second plurality of microfeatures is hydrophobic such that when exposed to an aqueous environment, only a partial volume of the microstructure is hydrated.
