A suture assembly comprising: a first suture having a generally U-shaped configuration comprising a first arm, a second arm and a first bridge connecting the first arm of the first suture to the second arm of the first suture, wherein the first arm of the first suture and the second arm of the first suture extend proximally from the first bridge; a second suture having a generally u-shaped configuration comprising a first arm, a second arm and a second bridge connecting the first arm of the second suture to the second arm of the second suture, wherein the first arm of the second suture and the second arm of the second suture extend distally from the second bridge; the first arm of the second suture being wrapped in a first helical arrangement around the first arm of the first suture in a clockwise and distal direction, and the second arm of the second suture being wrapped in a second, oppositely wound helical arrangement around the second arm of the first suture in a counterclockwise and distal direction; wherein the first arm of the second suture is wrapped three times around the first arm of the first suture and the second arm of the second suture is wrapped three times around the second arm of the first suture; the suture assembly is designed to be capable of assuming (i) a longitudinally-extended, radially-contracted first configuration, in which the wrapped portions of the second suture are longitudinally-extended and radially-contracted, wherein the first bridge of the first suture is spaced a first distance from the second bridge of the second suture, and (ii) a longitudinally-contracted, radially-expanded second configuration, in which the wrapped portions of the second suture are longitudinally-contracted and radially-expanded, wherein the first bridge of the first suture is spaced a second distance from the second bridge of the second suture, with the second distance being shorter than the first distance; wherein in the longitudinally-extended, radially-contracted first configuration, the wrapped portions of second suture extend a first length along a longitudinal central axis, the longitudinal central axis between and parallel to the first arm and second arm of the first suture, and the wrapped portions of second suture have a first radial width extending perpendicularly from the longitudinal central axis; and wherein in the longitudinally-contracted, radially-expanded second configuration, the wrapped portions of the second suture extend a second length, shorter than the first length, along the longitudinal central axis and have a second radial width, larger than the first radial width, extending perpendicularly from the longitudinal central axis, characterized in that the first and second ends (45, 50) of the second suture are connected to one another so as to form a loop. a first suture having a generally U-shaped configuration comprising a first arm, a second arm and a first bridge connecting the first arm of the first suture to the second arm of the first suture, wherein the first arm of the first suture and the second arm of the first suture extend proximally from the first bridge; a second suture having a generally u-shaped configuration comprising a first arm, a second arm and a second bridge connecting the first arm of the second suture to the second arm of the second suture, wherein the first arm of the second suture and the second arm of the second suture extend distally from the second bridge; the first arm of the second suture being wrapped in a first helical arrangement around the first arm of the first suture in a clockwise and distal direction, and the second arm of the second suture being wrapped in a second, oppositely wound helical arrangement around the second arm of the first suture in a counterclockwise and distal direction; wherein the first arm of the second suture is wrapped three times around the first arm of the first suture and the second arm of the second suture is wrapped three times around the second arm of the first suture; the suture assembly is designed to be capable of assuming (i) a longitudinally-extended, radially-contracted first configuration, in which the wrapped portions of the second suture are longitudinally-extended and radially-contracted, wherein the first bridge of the first suture is spaced a first distance from the second bridge of the second suture, and (ii) a longitudinally-contracted, radially-expanded second configuration, in which the wrapped portions of the second suture are longitudinally-contracted and radially-expanded, wherein the first bridge of the first suture is spaced a second distance from the second bridge of the second suture, with the second distance being shorter than the first distance;
