<p>A suture tensioning device (10) is described that comprises first (12) and second (14) jaws in facing relationship and oriented in parallel to each other. The first (12) and second (14) jaws are disposed in relative slidable engaement so that one of the jaws is adapted for parallel movement towards and away from the other jaw to define a variable gap (13) between them. A suture retainer (38) is engaged with a surface (30) of the second jaw (14) to enable a suture (20) to be tied so that the suture (20) exerts a variable tension on the surface (30) caused by the variable gap (13) between the first (12) and second (14) parallel jaws. Preferably, the first jaw (12) has defined therein a shape (42) designed to engage with a surface (16) from which a suture emanates. Preferably, the device includes two L-shaped elements (24, 25), each element having a shorter (28, 31) and a longer (26, 32) arm in orthogonal relationship. The longer arms (26, 32) of the respective support elements (24, 25) are slidably engaged with each other and adapted for movement from a first position, wherein the shorter arms (28, 31) are in registration and spaced apart from each other, to a second position, where the shorter arms (28, 31) are in registration and are closer together or farther apart than at the first position, so that a variable gap (13) between the shorter arms (28, 31) is defined. A suture retainer is engaged with one (28) of shorter arms and adapted for tying off a suture (20) emanating from a surface (16) and a conforming element (42) is engaged with the other arm (31). Methods for adjustably tensioning a suture (20) and a kit for performing suspension of a tissue (22) are described.</p> |
