A method of production of a tubular device for treatment of ischemic tissue, comprising dip coating a mandrel in potassium palmitate solution and drying in air, cross-link a tubular device in vapors of a 50% glutar-aldehyde solution, evaporating excess glutar-aldehyde solution by air-drying or vacuum drying the cross-linked tubes in 20-30 mTorr of pressure, scoring and cutting the tubular device into segments, soaking the tubular device in water or water-based solution, placing the tubular device so as to surround the mandrel and placing a sleeve over the tubular device so as to enable the tubular device to be injected into tissue.
