System for providing surgical access

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 plurality of helical members, each having proximal and distal ends and a helical shape, each proximal end coupled to the delivery member distal end, each distal end extending distally of the delivery member distal end; a plurality of anchor members removably coupled to the helical member distal ends; and a plurality of suture members coupled distally to a portion of one of the anchor members and extending proximally to a position wherein at least a portion of each may be freely manipulated by an operator; wherein upon rotation of the delivery member in a first direction, the helical members and coupled anchor members are advanced across at least a portion of the wall of the tissue structure, pulling along the distal portions of the suture members in a deployed suture pattern which remains coupled to the anchor member.
