Abstract

An intra-luminal expander assembly for use with a catheter comprises an expandable tubular expander element having openings, for example slots, formed in it, and first and second fixation portions located at or towards its ends. The expander element is disposed around a core element which comprises a shape memory alloy which has been treated so that, when the temperature of the alloy is increased above its A S temperature, it displays a shape memory effect and the length of the core element decreases. The expander element is attached to the core element through the first fixation portion and oriented so that, as the core element decreases when its temperature increases, the first fixation portion is caused to move relative to the second fixation portion in a direction towards the second fixation portion, and the second fixation portion being restrained against movement with the first fixation portion so that the length of the expander element decreases and its transverse dimension increases.
