  • Publication number: 20250082483
    Abstract: An endovascular system includes a delivery device operable to advance and/or retract a tubular implant disposed in the lumen of a catheter. The delivery device comprises a delivery wire, a set of stoppers comprising a distal stopper and a proximal stopper fixedly attached to the delivery wire, and a coupler disposed between the distal stopper and the proximal stopper of the set. The coupler is configured to contact and apply an outwardly radial force to a distal end portion of the tubular implant in the lumen of the catheter to grip the tubular implant in the lumen of the catheter. The proximal stopper of the set is configured to engage the coupler when the delivery wire is advanced to apply a translating force in a distal direction to the coupler thereby generating a pulling force in the distal direction on a portion of the tubular implant proximal of the distal end portion of the tubular implant.
