Abstract

Abstract Translated from German Tumor-Gallengangprothese aus Glaskohlenstoff. Die Prothese in Form eines geraden oder gekrümmten Rohrs (1) weist an der äußeren Oberfläche rillenartige Vertiefungen (2) und Mikroporen (3) auf, die innere Oberfläche (4) ist vorzugsweise poliert. Die Prothesen verkrusten nicht bei der Benutzung und weisen aufgrund ihrer Gewebskompatibilität ein vorzügliches Anwachsverhalten auf. Tumor bile duct prosthesis made of vitreous carbon. The prosthesis in the form of a straight or curved tube (1) has groove-like depressions (2) and micropores (3) on the outer surface, the inner surface (4) is preferably polished. The prostheses do not crust when in use and, due to their tissue compatibility, show excellent growth behavior.
