Abstract
The invention relates to a vessel prosthesis, particularly for the replacement of aorta segments near the heart, in the form of a pleated flexible tube with folds (3), the tube being configured as an arc, and the arc shape being fixed in an extension-resistant manner, in the non-implanted state, by means of extension limiters.
Claims11
A vessel prosthesis for the replacement of aorta segments near the heart comprising a pleated flexible tube with folds,
- the tube being configured as an arc,
- the arc shape being fixed in an extension-resistant manner, in the non-implanted state, by means of at least one continuous extension limiter running in the longitudinal direction and/or a multiplicity of extension limiters running in the transverse direction, and
- the folds of the pleating being gathered together to fix the arc,
- wherein the prosthesis has, as an extension limiter, at least one seam with at least eight through-runs, the at least one seam running in the longitudinal direction and/or in the circumferential direction of the prosthesis, and
- wherein the at least one seam in the longitudinal direction has at least one continuous thread with thread ends, the at least one continuous thread running at least on the inner side of the arc, passing through the folds of the pleated tube and having, between the thread ends, intermediate ties.
