Delivery system for tubular braided devices

An endovascular system, comprising:

• a catheter having a lumen;
• a tubular implant having a collapsed state for being disposed in the lumen of the catheter and an expanded state when unconstrained by the catheter;
• and
• a delivery device operable to advance and/or retract the tubular implant relative to the catheter, wherein the delivery device comprises:
• a delivery wire;
• a first set of stoppers comprising a distal stopper and a proximal stopper fixedly attached to the delivery wire;
• a first coupler disposed between the distal stopper and the proximal stopper of the first set, the first coupler being 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;
• a second set of stoppers comprising a distal stopper and a proximal stopper fixedly attached to the delivery wire;
• and
• a second coupler disposed between the distal stopper and the proximal stopper of the second set, the second coupler being configured to contact and apply an outwardly radial force to a proximal end portion of the tubular implant in the lumen of the catheter to grip the tubular implant in the lumen of the catheter, wherein
• the proximal stopper of the first set is configured to engage the first coupler when the delivery wire is advanced to apply a translating force in a distal direction to the first 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;
• and
• the distal stopper of the second set is configured to engage the second coupler when the delivery wire is retracted to apply a translating force in a proximal direction to the second coupler thereby generating a pulling force in the proximal direction on a portion of the tubular implant distal of the proximal end portion of the tubular implant.
