摘要：
A stent delivery system and a method for implanting a stent are provided. The system includes an elongate shaft including a proximal portion, a distal portion, a lumen extending at least partially therethrough, and a stent-receiving portion on the distal shaft portion. The system also includes a stent positioned at the stent-receiving portion of the elongate shaft, the stent having a constrained configuration and an expanded configuration. Proximal and distal constraining members releasably connected to the stent and having a first position and a second position are also included. The proximal and distal constraining members cooperatively apply longitudinal tensile force to at least a portion of the stent with the proximal and distal constraining members each in the first position. A drive system configured to simultaneously move the proximal and distal constraining members is provided, including a threaded drive shaft in mechanical communication with a rotatable handle.
