In one form of the present invention, there is provided apparatus for suturing tissue, wherein the apparatus comprises: a housing; a first needle mounted to the housing; a second needle mounted to the housing; a suture having a leading portion and a trailing portion; a first structure associated with the first needle for passing the leading portion of the suture from a near side of the tissue to a far side of the tissue; and a second structure associated with the second needle for retracting the leading portion of the suture from the far side of the tissue back to the near side of the tissue. In another form of the present invention, there is provided apparatus for suturing tissue, wherein the apparatus comprises: a housing; a first needle mounted to the housing; a second needle mounted to the housing; a suture having a leading portion and a trailing portion; a first structure associated with the first needle for passing the leading portion of the suture from a near side of the tissue to a far side of the tissue; a second structure associated with the second needle for retracting the leading portion of the suture from the far side of the tissue back to the near side of the tissue; a pre-formed, uncinched knot formed in the trailing portion of the suture; and a support for releasably supporting the preformed, uncinched knot relative to the housing. In another form of the present invention, there is provided a method for suturing tissue, the method comprising the steps of: providing a suture having a leading portion and a trailing portion, wherein a pre-formed, uncinched knot is formed in the trailing portion of the suture; passing the leading portion of suture from a near side of the tissue to a far side of the tissue; retracting the leading portion of the suture from the far side of the tissue back to the near side of the tissue;. passing the retracted leading portion of the suture through the pre-formed, uncinched knot formed in the trailing portion of the suture; and cinching the knot so as to secure the suture in the tissue. |
