1. An apparatus for closing a hole in a vessel, comprising:

  • a. a delivery assembly comprising a delivery sheath and a foot member having proximal and distal portions and a flexible portion therebetween,wherein the flexible portion is capable of accommodating rotation of the distal portion relative to the proximal portion,b. a rotation activating member comprising an elongate bending spring member coupled to the proximal and distal portions of the foot member, said spring member being adapted to cause the distal portion of the foot member to rotate relative to the proximal portion of the foot member;

    c. an implantable closure device having proximal and distal ends, the implantable device being removably coupled to the distal end of the foot 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 sufficient to substantially occlude the hole; and

    d. an elongate member housed in said delivery assembly, a catch member coupled to said elongate member and 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 to prevent withdrawal of the implantable closure device back through the hole.
