An areal implant has a flexible basic structure on a polymer basis (1) and ultrasonically detectable elements (2) which contain or produce gas and which are set up for detectability for at least four weeks after implantation. The implant can be non-ultrasonically detectable elements are foams (2) or microcapsules embedded in a matrix. The ultrasonically detectable elements are preferably designed as pre-shaped bodies (2) or linear structures such as e.g. threads. |
