Abstract: Embodiments relate to the use of auxetic geometries to construct the pores of membranes. Auxetic geometries expand in the transverse direction when stretched along the longitudinal direction. This behavior is counterintuitive as most materials contract in the transverse direction when stretched longitudinally. A mesh with pores that are auxetic has the potential to overcome the primary limitation of most prolapse meshes—pore collapse with tensile loading.
