Abstract

"HIDROGEL DE POLIACRILAMIDA E SUA UTILIZAçãO COMO UMA ENDOPRóTESE". Foi descoberto que hidrogeles de poliacrilamida compreendendo menos do que 3,5% de poliacrilamida, reticulada com metileno bisacrilamida, e pelo menos 95% de água, ou solução salina, são estáveis. Esses hidrogeles são úteis como recursos de endoprótese injetável ou implantável para utilização em mamoplastia, preenchimento de tecido mole, aumento do pênis, correção facial, aumento do lábio, delineamento do corpo, artrite, incontinência, esofagite de refluxo, e refluxo vesicouretal. São descritos também hidrogeles compreendendo de 0,5 a 25% de hidrogel de poliacrilamida para utilização como recursos protéticos. Os hidrogeles são preparados sob medida para seu uso pretendido como recursos protéticos, em termos de suas propriedades físicas e reológicas, tais como seu conteúdo em poliacrilamida, viscosidade e elasticidade."Polyacrylamide hydrogel and its use as an endoprosthesis". It has been found that polyacrylamide hydrogels comprising less than 3.5% methylene bisacrylamide cross-linked polyacrylamide, and at least 95% water, or saline, are stable. These hydrogels are useful as injectable or implantable stent graft features for use in mammoplasty, soft tissue filling, penis enlargement, facial correction, lip augmentation, body design, arthritis, incontinence, reflux esophagitis, and vesicouretal reflux. Also described are hydrogels comprising from 0.5 to 25% polyacrylamide hydrogel for use as prosthetic resources. Hydrogels are custom-made for their intended use as prosthetic resources in terms of their physical and rheological properties, such as their polyacrylamide content, viscosity and elasticity.
