Described herein are a system (100) and a method for forming a stent of a desiredlength endoluminally. The system includes an elongate stent body (105) and anouter sheath (110) overlying the stent body. An endoluminal cutting mechanism(115) is operatively connected to a drive cable (120) in communication with theouter sheath. The cutting mechanism is configured to cut the stent body in responseto motion of the drive cable. The method of forming the stent of a desired lengthendoluminally includes directing a system including an elongate stent bodyand an outer sheath overlying the stent body into a body lumen, positioning thestent body at an endoluminal site, and severing the stent body to form a stent ofa desired length at the endoluminal site. An undeployed portion of the stent bodyremains in the outer sheath for optional deployment in a subsequent severingoperation.
