| 摘要 |
<p>This invention is a low profile system for delivery of a medical treatment device, such as a stent (140) in a body vessel lumen. The delivery system includes an inflatable balloon (120) mounted on a balloon catheter (128), an insertion tip (110) secured to the distal end of the balloon (120) or the balloon catheter, (28) and the stent (140), mounted on the balloon (120) proximate to the insertion tip (110). The delivery system is placed into a body vessel within a delivery catheter (130) using an appropriate guiding system. The overall diameter of the delivery system/delivery catheter assembly permits delivery of even relatively large stents into small diameter body vessel lumens, such as those of the pulmonary arteries in a yound child. Methods for use of the delivery system are also provided.</p> |
