Abstract
A stent 1 comprising a sheet 2 of biocompatible material arranged as a tube and having a pattern of folds allowing the stent to be collapsed for deployment. The pattern of folds comprises a unit cell repeated over the sheet 2. A variety of different unit cells 3 are described. The pattern of folds may progress helically around the tube which assists in implantation by synchronising deployment. The stent 1 prevents restenosis because it is formed of a continuous sheet 2, and allows slippage to be minimised.
