Claim:
A surgical implant made from biocompatible fiber material as a woven textile fabric, including warp and weft threads, in the form of a vascular prosthesis, the woven textile fabric configured essentially in a plain weave and having a base structure in plain weave, the woven textile fabric configured to have a permeability to blood, to which anticoagulants have been added, said blood permeability sufficiently low that the blood impregnates the textile fabric upon implantation and seals it off by coagulating, and the woven textile fabric having a water permeability in the range of 100 to 300 ml/cm 2 per minute, wherein the woven fabric is configured with 30 to 120 warp threads and 10 to 70 weft threads per centimeter, only flat threads are used as weft threads, and flat and texturized threads are used as warp threads, the ratio of flat threads to textured threads in the warp threads being between 2:1 to 1:2 and textured floating threads extending in the warp direction are included that float only on the outer surface of the vascular prosthesis and the floating threads lie flat in the woven textile fabric surface and do not form loops.
