摘要: A transcatheter delivery device for delivering a slide-and-lock stent to a stenosed lumen consists of an outer cannula (3), an inner sheath (2) and a balloon catheter (1). The distal end of the balloon catheter (1) is a balloon (5). The length and diameter of the balloon (5) can be chosen according to the requirement of the stent. A cone (4) is attached to the distal end of the balloon (5) to prevent the stent sliding to the distal end. The proximal part of the cone (4) can be inserted into the outer cannula (3) to maintain the external surfaces of the cone (4) and the outer cannula (3) on the same level. The inner sheath (2) is a little shorter than the balloon catheter (1) and extends to the proximal end of the balloon (5) so as to prevent the stent sliding to the proximal end.
