Scanning electron microscopy and X-ray diffraction studies in the analysisof medical materials: Gore-Tex (R) versus braided polyester tape for repair of the incompetent cervix

Cathodoluminescence in the scanning electron microscope and roentgenogram d iffraction studies were applied to the analysis of two different medical ma terials used in cervical cerclage, the treatment of cervical incompetence. Braided polyester tape or Gore-Tex(R) was used as suture material and was a nalyzed both before and after use in cerclage of the cervix. Results of SEM and X-ray diffraction studies showed distinct differences between the two materials, with the Gore-Tex(R) demonstrating a superior morphological inte grity and a decreased likelihood of pha,oocyte adhesion. These results corr elated well with the clinical observations, which also showed Gore-Tex(R) t o be a superior medical material. (C) 1999 Elsevier Science Ltd. All rights reserved.
