The present invention provides two or more types of grafts having different absorption rates to be transplanted to an anatomical tissue site of a mammalian patient. A plurality of bioabsorbable composite particles, each composite particle including a site derived from each of two different extracellular matrix materials, wherein one of the two extracellular matrix materials is the two cells. An implant having a density of at least 150% of the other density of the outer matrix material, wherein one extracellular matrix material has a different absorption rate from the other extracellular matrix material by 1-50. The surgical device is further selected from a stent, a cardiac occluder, a suture material and a mesh. [Selection] Figure 3 |
