Abstract:
1. An apparatus for closing a hole in a vessel comprising: a sheath; a deployment member having proximal and distal ends; an implantable closure device having proximal and distal ends, the implantable device being removably coupled to the distal end of the deployment member and being expandable from a collapsed state to an expanded state after the implantable device is inserted through the hole into a lumen defined by the vessel, the expanded state providing a geometry to substantially occlude the hole; a catch member configured to extend away from the proximal end of the implantable device by a catch member length, wherein the catch member length is selected to extend within the lumen and disposed relative to the implantable device to prevent withdrawal of the implantable closure device back through the hole prior to expansion to said expanded state and wherein the deployment member and catch member are slidable within the sheath; a foot member having proximal and distal ends and a flexible portion therebetween, the flexible portion accommodating rotation of the distal end relative to the proximal end, wherein the distal end of the foot member is releasably coupled to the closure device and the proximal end of the foot member is coupled to the deployment member; a rotation actuating member coupled to the distal end of the foot member to controllably rotate to the proximal end of the foot member; and wherein the rotation actuating member comprises an elongate bending spring member coupled to the proximal and distal portions of the foot member.
