摘要： The coil stent delivery system and method of use includes a stent delivery system including a coil stent; a housing, the housing having a receiver defining a receiver chamber and a sheath defining a sheath lumen, the receiver chamber being in communication with the sheath lumen; and a screw assembly, the screw assembly having a shaft, a helical screw disposed about a distal portion of the shaft, and a drive operably coupled to the shaft. The shaft is disposed in the receiver chamber and the sheath lumen, the helical screw is disposed in the sheath, and the coil stent is disposed about the shaft in the receiver chamber and engages the helical screw. Rotation of the drive moves the coil stent through the sheath lumen.
