An implant delivery system (10) including a catheter (60) having a delivery lumen (66); a pusher member (30) slidably disposed in the catheter delivery lumen; a retaining member (50) coupled to a distal end portion of the pusher member, the retaining member configured to retain an expandable implant in a collapsed configuration on the pusher member for delivery of the implant through the catheter delivery lumen; and an expandable actuator (40) coupled to the distal end portion of the pusher member and operatively associated with the retaining member, wherein expansion of the actuator causes the retaining member to disengage from an implant (20) carried on the pusher member, to thereby allow the implant to expand from the collapsed configuration. |
