APPLICATION OF COMPOSITION CONTAINING TELECHELIC MACROMER AND PHOTOINITIATOR FOR PRODUCING IMPLANT FOR HERNIA REPAIR

摘要

The present invention relates to an application of a composition containing telechelic macromer and photoinitiator for producing implant for hernia repair. The macromer structure is defined by Formula 1. The macromer bears (meth)acrylic end-groups and comprises a core Y defined by Formulas 2 to 9, that is linked by urethane, ester or anhydride bonds to the (meth)acrylic groups. The iodine value of the macromer is from 5 to 75. The composition according to the present invention can be shaped at room temperature and at 37° C. and is capable of undergoing liquid-to-solid transition upon irradiation with low intensity light. Upon irradiation with light the composition gains desired physicochemical properties and turns into an elastic solid. The implant for hernia repair serves for closing the hernia opening and for enhancing mechanical strength of abdominal wall.
