Abstract
A device for use in reducing or preventing the occurrence of restenosis following procedures such as PTCA, in which a stent is used to hold a bodily lumen open. The device comprises a two layered stent, one lying within the other. Both stent layers have an open weave structure, such that they can expand to the correct dimensions after implantation. The outer stent layer is static and grips the inner wall of the lumen in which it is deployed in the usual manner. The inner layer stent is constructed such that it can be vibrated relative to the outer static stent layer. The inner layer stent may be made of a material which can be vibrated from an external source, such as a ferromagnetic material. This vibration prevents restenosis of the treated lumen. Alternatively, a vibrator, such as a piezoelectric device, can be installed on the inner stent layer.
