Abstract
A tubular knitted stent or stent graft for placement in a lumen or body passage is compressible, thus presenting a compressed outer diameter and a non-compressed outer diameter. The stent or stent graft has knitted loops each having a loop width, wherein the loop width to non-compressed outer diameter ratio is larger than 0.2 for at least one knitted loop.

A tubular knitted stent or stent graft for placement in a lumen or body passage, the stent or stent graft being compressible and having a compressed and a non-compressed outer diameter, the stent or stent graft having knitted loops each having a loop width,
- wherein at least one knitted loop is characterized by a loop width to non-compressed outer diameter ratio larger than 0.2.
A method for fabricating a tubular stent or stent graft for placement in a lumen or body passage, the method comprising:
- knitting a tubular stent or stent graft which is compressible and has a compressed and a non-compressed outer diameter, the stent or stent graft having knitted loops each having a loop width,
- wherein the loop width to non-compressed outer diameter ratio is larger than 0.2 for at least one knitted loop;
- crimping the stent or stent graft to a compressed outer diameter smaller than the non-compressed outer diameter.
