Abstract: Stent delivery systems and methods for making and using the same are disclosed. An example stent delivery system may include an inner member having a proximal end. A sleeve may be coupled to the inner member adjacent to the proximal end. A deployment sheath may be disposed about the inner member. A gear rack assembly may be coupled to the deployment sheath. A stent may be disposed between the inner member and the deployment sheath. A handle may be coupled to the inner member and to the deployment sheath. The handle may include an actuation member. The actuation member may be coupled to the gear rack assembly so that actuation of the actuation to member shifts the longitudinal position of the gear rack assembly and the deployment sheath. An engagement mechanism may be coupled to the gear rack assembly. The engagement mechanism may be configured to engage the sleeve of the inner member so that proximal retraction of the gear rack assembly results in proximal retraction of the inner shaft.

Abstract: A stent delivery system including a stent disposed between an inner member and a deployment sheath is disclosed. Additionally, the stent delivery system includes a handle that may be coupled to the inner member and to the deployment sheath. The handle may include an actuation member coupled to the gear rack assembly so that actuation of the actuation member shifts the longitudinal position of the gear rack assembly and the deployment sheath. The gear rack assembly may include an engagement mechanism that may be configured to engage the inner member so that proximal retraction of the gear rack assembly results in proximal retraction of the inner shaft.

Abstract: Medical systems and devices are described. In one example, a system for delivering an implantable endoprosthesis into a body vessel is described. The system includes a handle assembly having a housing, a rotatable member, a first pulley engaged to the rotatable member, a second pulley rotatably engaged to the housing, and a belt extending between the first pulley and the second pulley, the belt engaged to the first pulley. The system further includes an inner member, an outer sheath secured to the belt and disposed about at least a portion of the inner member. The system excludes a rack.
