US Patent 9480585 Implant of low radial strength

The invention concerns an endovascular implant comprising a biodegradable material and having a tubular main body which is open at the ends and which is dilatable from an unexpanded condition into an expanded condition. The implant is so designed that when the implant in the expanded condition is subjected to a radially acting compression pressure in the range of between 5 and 30 kPa (0.05-0.3 bar)a cross-sectional area of the implant is reduced to 70% or less of the original cross-sectional area, oran internal volume of the implant is reduced to 70% or less of the original internal volume.
