Abstract
EL METODO DE ACUERDO CON LA INVENCION, REPRESENTA UNA MEJORA DEL METODO CONOCIDO EN SI PARA LA FABRICACION DE PROTESIS, EL CUAL SE COMPONE DE UN PORTADOR ARTIFICIAL PREFORMADO, EN CUYA ZONA SUPERFICIAL SE IMPLANTAN CELULAS Y ASOCIACIONES DE CELULAS DEL PROPIO CUERPO, LAS CUALES DESPUES DE LA IMPLANTACION INICIAN UN REVESTIMIENTO DE LA SUPERFICIE DE LA PROTESIS O DE PARTES DE ESTA SUPERFICIE CON UNA CAPA VIVA. SE HA VISTO QUE TAMBIEN CUANDO LAS CELULAS Y ASOCIACIONES DE CELULAS A IMPLANTAR PROCEDEN DE UN TEJIDO, QUE ADEMAS DE ESTAS CELULAS TAMBIEN CONTIENE OTRAS CELULAS Y COMPONENTES DE TEJIDOS NO CELULARES, NO ES NECESARIO UN AISLAMIENTO DE LAS CELULAS DESEADAS ANTES DEL IMPLANTE. POR ESTE MOTIVO DE ACUERDO CON EL METODO DE LA INVENCION, SE PUEDE RENUNCIAR A UNA PREPARACION COMPLICADA Y DE LARGA DURACION DEL MATERIAL DEL TEJIDO EMPLEADO PARA EL AISLAMIENTO DE LAS CELULAS DESEADAS, TAL COMO SE DESCRIBE PARA EL CORRESPONDIENTE METODO CONFORME AL ESTADO DE LA TECNICA. EL MATERIAL DEL TEJIDO, EN ESENCIA SE TRITURA MECANICAMENTE Y SE SUSPENDE Y, CUANDO ES NECESARIO, ADICIONALMENTE DE MODO ENZIMATICO EN PARTICULAS DE TEJIDO, CUYAS DIMENSIONES ESTAN ENTRE LOS LIMITES MAS ESTRECHOS POSIBLES Y EL MATERIAL PORTANTE PREFORMADO SE TRATA CON LA SUSPENSION, PARA LO CUAL CON MATERIAL PORTANTE POROSO, SE FILTRA LA SUSPENSION POR EL MATERIAL, CON MATERIAL PORTANTE POCO POROSO O NO POROSO, SE LLEVA LA SUSPENSION POR CENTRIFUGACION A LA SUPERFICIE DEL MATERIAL PORTANTE. EN OPOSICION A LOS CORRESPONDIENTES METODOS SEGUN EL ESTADO DE LA TECNICA, SE PUEDE REALIZAR EL METODO DE ACUERDO CON LA INVENCION EN MUY POCO TIEMPO GRACIAS A LA MEJORA, POR TANTO, DIRECTAMENTE DURANTE LA OPERACION Y EN UN SISTEMA CERRADO.
