It is an object of the present invention to provide a laser-welded article that workpieces prepared simply can be easily unified by laser in one laser welding process without using complicated processes. Moreover, the laser-welded article has an excellent appearance and sufficient welding strength of the molded workpieces, and does not damage the resin property. The laser-welded article comprises: an integral construction of a single workpiece that at least a part of curled workpiece is overlapped or plural workpieces that at least a part of each workpiece is piled, which is welded by exothermic through irradiating laser, wherein the single laser-transmissible-absorptive molded workpiece or the plural laser-transmissible-absorptive molded workpieces include a thermoplastic resin and a laser-transmissible absorbent to have an absorbance: a ranging from 0.07 to 2.0, and have abilities of absorbing at least partial beam of the laser and transmitting another partial beam of the laser.

The invention is directed to bioengineered tubular graft prostheses prepared from cleaned tissue material derived from animal sources. The bioengineered graft prostheses of the invention are prepared using methods that preserve cell compatibility, strength, and bioremodelability of the processed tissue matrix. The bioengineered graft prostheses are used for implantation, repair, or for use in a mammalian host.
