An in vivo supporting device, comprising:
- a biodegradable metal scaffold;
- and
- a biodegradable polymer coating covering at least a portion of said biodegradable metal scaffold,
- wherein said biodegradable polymer coating has a thickness of 10-200 μm and a degradation rate that is different than the degradation rate of said biodegradable metal scaffold,
- wherein said biodegradable metal scaffold comprises an alloy,
- wherein the alloy comprises magnesium, manganese, and at least one rare earth metal,
- wherein the biodegradable metal scaffold comprises metal struts,
- wherein the biodegradable polymer coating partially covers the metal struts, but does not cover openings between the struts, and
- wherein the struts from the biodegradable metal scaffold are fully encapsulated by the biodegradable polymer coating and the coated struts and openings therebetween are fully covered by the biodegradable polymer covering.
