| 主权项 | 1. A biodegradable tissue fixation device, comprising: a first component comprising a polymer, having an outer surface and having interconnecting pores; a second component disposed in the pores of the first component, such that the first component is non-porous; wherein the second component further forms a non-porous layer that covers the outer surface of the first component except in defined areas; and wherein the first component has a higher rate of in vivo degradation than the second component. | ||
