Abstract
Various embodiments are described for a stent delivery device that utilizes a push button using a slot and pin on a shuttle with a rack for slow retraction of the outer sheath as well as a flanged member connected to the outer sheath for fast retraction of the outer sheath during delivery of a self-expanding implantable device such as a stent or stent graft.
Claims14
A stent delivery system comprising
- a catheter tip coupled to an inner shaft and an outer sheath with a stent disposed between the inner shaft and the outer sheath, the inner shaft and the outer sheath extending from a distal end to a proximal end;
- a primary rack connected to the outer sheath;
- and
- a housing enclosing a portion of the primary rack, the housing extending along a longitudinal axis from a first end to a second end, wherein the housing includes:
- a button coupled to the housing to allow for movement of the button along an arc, the button defining at least a side member generally parallel to the longitudinal axis, the side member having a slot that approximates a curve;
- and
- a shuttle disposed partly in the button, the shuttle having a secondary rack configured to mate with a portion of the primary rack, the shuttle having a pin extending through the shuttle and the slot so that movement of the button towards the longitudinal axis forces the primary rack to translate along the longitudinal axis due to motion of the slot of the button against the pin of the shuttle.
