Abstract
A stent deployment device and methods for use, where the device comprises: (a) an outer sheath having a proximal end and a distal end, (b) a pull apparatus at least partially disposed within the outer sheath, where a portion of the pull apparatus is sized and shaped to receive a stent or a stent graft, (c) a push apparatus, where a portion of the push apparatus is sized to fit within a portion of the pull apparatus, and (d) a push-pull drive mechanism in mechanical communication with the pull and push apparatuses, where the push-pull drive mechanism includes at least a push and a pull gear or a push and a pull reel sized and shaped based on a stent ratio.
Claims31
A stent deployment device, comprising:
- an outer sheath, wherein the outer sheath has a proximal end and a distal end;
- a pull apparatus at least partially disposed within the outer sheath, wherein a portion of the pull apparatus is sized and shaped to receive a stent or a stent graft, wherein a proximal end of the pull apparatus comprises a ribbon that transitions to a pull shaft and the pull shaft then transitions to a pull tube;
- and
- a push apparatus, wherein a portion of the push apparatus is sized to fit within a portion of the pull apparatus, wherein a proximal end of the push apparatus comprises a ribbon that transitions to a push shaft.

A stent deployment device, comprising:
- an outer sheath, wherein the outer sheath has a proximal end and a distal end;
- a pull apparatus at least partially disposed within the outer sheath, wherein a portion of the pull apparatus is sized and shaped to receive a stent or a stent graft;
- a push apparatus, wherein a portion of the push apparatus is sized to fit within a portion of the pull apparatus;
- and
- a push-pull drive mechanism in mechanical communication with the pull apparatus and the push apparatus, wherein the push-pull drive mechanism includes at least a push gear and a pull gear or a push reel and a pull reel, wherein either a ratio of a diameter of the pull gear to a diameter of the push gear or a ratio of a diameter of the push reel to a diameter of the pull reel is equal to a stent ratio plus 5-15% of the stent ratio.
