1. A suturing assembly comprising:
a suture passing member formed with a lumen in which are disposed a suture holding element and a first puncture element formed with a sharp distal end for puncturing tissue, both said first puncture element and said suture holding element comprising suture receiving portions; and a second puncture element comprising a suture receiving portion and a sharp distal end for puncturing tissue; wherein said first puncture element and said suture holding element have a retracted position and a deployed position, wherein in the retracted position, a distal end of said suture holding element does not protrude beyond the sharp distal end of said first puncture element; and in the deployed position: a. said first puncture element and said suture holding element are positioned further away from a distal end of said lumen than in the retracted position, b. the distal end of one of said first puncture element and said suture holding element bends and passes over the distal end of said second puncture element, c. a space is formed between said first puncture element and said suture holding element and said second puncture element is positioned opposite said space, and d. during movement of said first puncture element and said suture holding element from the deployed position back to the retracted position, the suture receiving portion of the one of said first puncture element and said suture holding element that passes over the distal end of said second puncture element, moves adjacent the suture receiving portion of said second puncture element. |
