Abstract
The present invention concerns a bio-resorbable prosthesis (1, 1′) for organs with lumens, as blood vessels and the like, comprising at least one bio-absorbable material layer (2), intended to be arranged in contact with said lumen organ when said prosthesis (1, 1′) is implanted, and at least one auxetic material layer (3), arranged in contact with said at least one bio-absorbable material layer (2). The present invention also concerns a method for the production of a bio-absorbable prosthesis (1, 1′).
Claims13
A prosthesis (1, 1′) for organs with lumens, which prosthesis comprises:
- at least one bio-absorbable material layer (2), configured to be arranged in contact with said lumen organ when said prosthesis (1, 1′) is implanted,
- at least one auxetic material layer (3), arranged in contact with and within said at least one bio-absorbable material layer (2), and
- a reinforcing layer, said reinforcing layer being coated by said auxetic material layer (3),
- wherein said prosthesis (1′) being usable as an endovascular prosthesis, which prosthesis is a stent:
- wherein said bio-absorbable material layer (2) is a mesh having a plurality of polygonally-shaped cells,
- wherein said bio-absorbable material layer (2) comprises polydioxanone (PDS),
- wherein said auxetic material layer (3) comprises a plurality of side longitudinal strips (31), arranged in parallel having an auxetic behavior in the longitudinal development direction,
- wherein said auxetic material layer (3) comprises expanded polytetrafluoroethylene (Goretex®), and
- wherein said reinforcing layer is made of metal.
