Stent-graft delivery system having handle mechanism for two-stage tip release

摘要

A delivery system for a stent-graft is disclosed having a tip capture device and a tip release handle mechanism configured to actuate the tip capture device. The tip release handle mechanism includes a rotatable grip component and a tip release actuation component. The grip component may be rotatable in a first direction to transition a proximal stent of the stent-graft from the delivery state to a partially deployed state and rotatable in an opposite, second direction to transition the proximal stent from the partially deployed state to a fully deployed state. The grip component is operably coupled to the tip release actuation component. The delivery system further includes a shaft component operably coupled to the tip release actuation component and the tip capture device.

1. A delivery system for a stent-graft comprising:
a tip capture device disposed at a distal end of the delivery system, wherein a proximal stent of a stent-graft is held in a delivery state by the tip capture device; a handle mechanism configured to deploy the proximal stent of the stent-graft, the handle mechanism having a grip component that is rotatable in a first direction to transition the proximal stent from the delivery state to a partially deployed state and that is rotatable in an opposite second direction to transition the proximal stent from the partially deployed state to a fully deployed state, and a tip release actuation component operably coupled to the grip component, wherein rotation of the grip component in each of the first and second directions rotates the tip release actuation component in the first direction; and a shaft component having a proximal end operably coupled to the tip release actuation component and a distal end operably coupled to the tip capture device.
