Abstract
An implant delivery system including a catheter having a delivery lumen; a pusher member slidably disposed in the catheter delivery lumen; a retaining member 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 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 carried on the pusher member, to thereby allow the implant to expand from the collapsed configuration.

7. An implant delivery system, comprising:
-
a catheter having a delivery lumen; a pusher member slidably disposed in the catheter delivery lumen; an expandable implant carried on a distal end portion of the pusher member; a plurality of retention members, each having a first end attached to the pusher member at a location distal to the implant, and a second end releasably engaging the implant to thereby retain the implant in a collapsed configuration on the pusher member for delivery of the implant through the catheter delivery lumen; and an inflatable membrane attached to the pusher member and having an exterior surface affixed to the respective retention members, the pusher member comprising an inflation lumen in communication with an interior region defined by the membrane, wherein inflation of the membrane causes the retaining members to disengage the implant and thereby allow the implant to expand from the collapsed configuration, the implant delivery system further comprising a guidewire disposed within the inflation lumen of the pusher member. - View Dependent Claims (8, 9, 10, 11, 13)
