Claim Text:
1. A method for closing a hole in a wall of a vessel, the vessel defining a vascular lumen, comprising: a. inserting a guidewire having proximal and distal ends through the hole and into said lumen; b. inserting over the guidewire and through the hole (i) an elongate deployment member housing an implantable closure device having proximal and distal ends and being expandable from a collapsed state to an expanded state, the expanded state providing a geometry sufficient to substantially occlude the hole and (ii) then first inserting the distal end of said closure device through said hole and into said lumen until the proximal end of said closure device passes through said hole and into said lumen; c. positioning the collapsed state of the implantable closure device adjacent the wall of the vessel in a configuration wherein the collapsed implantable closure device spans the hole from within the vascular lumen; d. deploying a catch member configured to extend away from the proximal end of the closure device to prevent withdrawal of the closure device in its collapsed state through the hole: e. expanding the implantable closure device from the collapsed state to the expanded state by decoupling the implantable closure device from the deployment member; f. controllably moving the catch member to a retracted configuration wherein the catch member is moveably coupled to and substantially aligned with the deployment member; and g. withdrawing said deployment member out through the hole and leaving behind said closure device.
