Abstract
One embodiment is directed to a system for providing surgical access across a wall of a tissue structure, comprising a delivery member having proximal and distal ends; a first helical member having proximal and distal ends and a helical shape, the proximal end coupled to the delivery member distal end, the distal end extending distally of the delivery member distal end; an anchor member removably coupled to the helical member distal end; and a suture member coupled distally to a portion of the anchor member and extending proximally to a position wherein at least a portion of it may be freely manipulated by an operator; wherein upon rotation of the delivery member in a first direction, the first helical member and coupled anchor member are advanced across at least a portion of the wall of the tissue structure, pulling along the distal portion of the suture member in a deployed suture pattern which remains coupled to the anchor member, the deployed suture pattern being characterized in that it is substantially helical and represents a number of helical loops encapsulated by the wall of the tissue structure that is greater than about one helical loop, and is less than about three helical loops.
