1. A closure device for closing an opening in tissue as part of a closure system, the closure device comprising:
a needle actuation handle cooperating with a housing;
a first hollow needle selectively movable by the needle actuation handle, the first hollow needle comprising a slot extending proximally from a distal end of the first hollow needle;
a suture anchor frictionally engaged with the slot and a lumen of the first hollow needle and coupled to a suture, a portion of the suture anchor that extends transversely to a portion of the suture anchor mounted to the suture resting along sides of an outer surface of the first hollow needle on opposite sides of a longitudinal axis of the first hollow needle as the first hollow needle is advanced through tissue adjacent the opening.
