Abstract
A needle and suture assembly includes a needle made of a superelastic alloy, such as Nitinol, including an elongated body having a proximal end and a distal end with a sharpened tip, a suture having a free end juxtaposed with the proximal end of the elongated body of the needle, and a connector disposed between the needle and the suture. The connector includes a first end attached to the proximal end of the elongated body of the needle and a second end attached to the free end of the suture. The connector is made of a material, such as stainless steel, having less elasticity and greater plasticity than the superelastic alloy of the needle.
