The paper studies the selection of appropriate sterilization technique for resorbable tubular structures made of poly( L-lactide-co-glicolide)( PLAGA) and nonbiodegradable tubular structures made of polypropylene( PP). The designed grafts are characterized by the physical properties as well as mechanical properties according to ISO 7198 ∶ 1998 Standard.Moreover,the process of the grafts fabrication will be explained considering the stages affected the critical properties of the elaborated textile implants. The increase of PLAGA melt-electrospun tubular structures mechanical properties was observed due to the thermal stabilization use. The ethylene oxide( EO) and steam sterilization had a destructive effect on the designed PLAGA meltelectrospun tubular, fibrous structures, whereas the irradiation yielded in the changes in mechanical and physical properties on the acceptable level,taking into account the future clinical applications. 关 键 词：VASCULAR PROSTHESES melt-electrospinning MELT-BLOWN STERILIZATION
