Abstract: A multistate register, comprising: a flip-flop that comprises a first latch, a second latch and an intermediate gate coupled between the first and second latches; multiple memristive devices; and an interface coupled between the multiple memristive devices and the flip-flop; wherein the multistate register is arranged to operate in a memristive device write mode, in a memristive device read mode and in a flip-flop mode; wherein when operating in the memristive device read mode, the interface is arranged to write to a first selected memristive device of the multiple memristive devices a first logic value stored in the first latch; wherein when operating in the memristive device write mode, the interface is arranged to write to the second latch a second logic value stored in a second selected memristive device of the multiple memristive devices; and wherein when operating on a flip-flop mode logic the interface is prevented from transferring values between the flip flop and the memristive devices.

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.
