摘要：
One embodiment is directed to a method for providing surgical access across a wall of a tissue structure, comprising: installing a guiding member into the wall of the tissue structure to a desired guiding depth； using the installed guiding member as a positional guide, advancing a helical member into the wall of the tissue to a desired helical member depth, the helical member comprising a helical member distal end removably coupled to an anchor member which is coupled to a distal end of a suture member, such that advancing the helical member into the wall causes the anchor member to be advanced into the wall and to pull a distal portion of the suture member along with the anchor member into the wall to substantially encapsulate a number of helical loops of suture member that is greater than about 1 loop and less than about 3 loops； withdrawing the helical member from the wall of the tissue structure, leaving the anchor member in a deployed configuration decoupled from the helical member and coupled to at least a portion of the wall of the tissue structure； and tensioning the suture member to apply a load to the deployed anchor member.
