Surgical fastening clips, systems and methods for proximating tissue

A method for surgically proximating tissue, the method comprising:

• providing a surgical fastener clip having an undeflected state in which a single wire of the clip defines:
• a center portion having a perimeter defining a circle-like shape,
• a first leg projecting relative to the perimeter from a point of departure to a tip to establish a spacing between the first leg and the perimeter,
• a second leg projecting relative to the perimeter from a point of departure to a tip to establish a spacing between the second leg and the perimeter,
• wherein extensions of each of the legs relative to the perimeter defines a wind direction that is one of clockwise and counterclockwise, the wind directions being identical;
• assembling the clip to a delivery device including a retainer, a tether and a sheath, wherein the retainer is slidably disposed within the sheath, wherein the retainer is an elongated tube, wherein the tether is disposed within the retainer, wherein the clip is selectively engaged by a distal region of the retainer and the clip is disposed within the sheath, the sheath maintaining the clip in a collapsed state, wherein the tether is releasably mounted to the clip;
• advancing the clip, in the collapsed state, to a location adjacent tissue to be proximated;
• releasing the clip from the sheath to allow the clip to transition from the collapsed state toward the undeflected state;
• rotating the clip via the retainer such that the tips pierce through tissue to be proximated;
• further rotating the clip via the retainer such that tissue to be proximated is gathered between each of the legs and a corresponding region of the center portion to at least partially proximate the tissue;
• and
• releasing the clip from the delivery device.
