Tissue Retractor Assembly

A tissue retractor assembly, comprising:

• a. a cannula defining an axis and a distal end;
• b. an anchor releasably engaged with respect to the distal end of the cannula, the anchor including (i) an outer tube and (ii) a central shaft that includes at least two barbs which are configured to be outwardly deployed when the central shaft is translated proximally relative to the cannula;
• c. a wire form releasably engaged with respect to the distal end of the cannula, the wire form including a coiled spring that is adapted to expand radially outward;
• d. a suture in cooperative association with the anchor and the wire form to facilitate movement of the wire form relative to the anchor.

A tissue retractor assembly, comprising:

• a. a cannula defining an axis and a distal end;
• b. a grasper adapted to extend from the distal end of the cannula, the grasper including a loop of suture and a one way locking toggle;
• c. an anchor releasably engaged with respect to the distal end of the cannula, the anchor including (i) a back span, (ii) one or more torsion springs, (iii) an axial connection between the back span and the one or more torsion springs, and (iv) at least two sharpened legs;
• and
• d. a suture in cooperative association with the anchor and the grasper to facilitate movement of the grasper relative to the anchor.

A tissue retractor assembly, comprising:

• a. a cannula defining an axis and a distal end;
• b. a first grasper detachably engaged relative to the distal end of the cannula, the first grasper including a first clip configured and dimensioned to be deployed axially from a distal end of the cannula to define a first C-shaped form;
• c. a second grasper detachably engaged relative to the distal end of the cannula, the second grasper including a second clip configured and dimensioned to be deployed axially from a distal end of the cannula to define a second C-shaped form;
• and
• d. a suture in cooperative association with the first grasper and the second grasper to facilitate movement of the first grasper relative to the second grasper.
