Abstract:
1. A method of closing an opening in tissue having a proximal surface using a device having a plurality of tissue engagement elements extending distally from a central junction and capable of occupying a plurality of compressed configurations and at least one expanded configuration and a separate locking element, said method comprising the steps of: passing the device while in a first one of the compressed configurations through a sheath disposed adjacent to an opening in the proximal surface of the tissue; expelling the device from the sheath into space beyond the proximal surface of the tissue such that the device assumes the at least one expanded configuration; manipulating the device such that the tissue engagement elements engage the tissue; following engaging the tissue with the tissue engagement elements, advancing the locking element along a flexible member from a proximal end of the flexible member toward the device and along the plurality of tissue engagement elements, the flexible member extending from a device proximal end at the central junction to a position remote from and proximal to the device proximal end; and moving the device to bring edges of the opening into apposition.
