摘要： The invention is directed to a biodegradable implant precursor having a two-part structure made of an outer sac and a liquid content. The implant precursor is composed of a biodegradable, water-coagulable thermoplastic polymer and a water-miscible organic solvent. When administered to an implant site in an animal, the implant precursor will solidify in situ to a solid, microporous matrix by dissipation of the organic solvent to surrounding tissue fluids and coagulation of the polymer. The invention also includes methods of making the implant precursor, an apparatus for forming the precursor, and a kit containing the apparatus. Also provided are methods of using the implant precursor for treating a tissue defect in an animal, for example, for enhancing cell growth and tissue regeneration, wound and organ repair, nerve regeneration, soft and hard tissue regeneration, and the like, for delivery of biologically-active substances to tissue or organs, and other like therapies.

摘要： A method of, and an apparatus for, applying a mold releasing agent to only necessary portions of a coagulation layer and capable of easily controlling an irradiation output of a laser beam. More particularly, it provides a method of, and an apparatus for, molding a laminate which can improve a work efficiency and can produce a laminate model having higher molding accuracy. To accomplish the objects, the present invention forms a slot groove (SG) in the coagulation layer (SL) by using a carbonic acid gas laser slot cutting machine (60) and divides a workpiece into a necessary region (SL1) for constituting a three-dimensional model and an unnecessary region not constituting a three-dimensional model. A laminate structure (LS) having a desired shape is obtained by repeating a slot forming step for forming the slot groove (SG), a mold releasing agent printing step for printing and applying the mold releasing agent (R) to a predetermined region (SL3) of the coagulation layer (SL), a coagulation agent applying step for applying the coagulation agent (S) to the uppermost surface of the laminate structure (LS) and a coagulation agent coagulating step for coagulating and curing the coagulant layer (SLL) applied and formed by a coagulation agent coagulating apparatus (50).
