摘要： This invention is a stent (1) and stent catheter (2) for intracranial use. The stent is a rolled sheet stent (20) and is releasably mounted on the distal tip (21) of the catheter by means of a low profile or non-sliding retention and release mechanism. The low profile or non-sliding release mechanism (22) is operated remotely at the proximal end of the catheter by means of a linear translator (23). The stent is rolled tightly on the distal tip of the catheter and flexibility of the tightly rolled stent is promoted by ribbed or slatted construction (or, alternatively, slotted construction) in which the various layers of the stent are provided with numerous slats which counter align when the stent is expanded to form an imperforate wall from a plurality of perforate layers.
