<p>A suture needle (10) having, in sequence, a shaft portion (11), a tip portion (13), a conical point portion (15) and a point (17). The shaft portion (11) may be straight or curved, and cylindrical or tapered. The tip portion (13) has at least two substantially flat surfaces (19). The conical point portion (15) is of conical shape having a substantially round cross section adjacent to the point (17) of the needle (10). A plane (25) tangent to the surface of the conical point portion (15) makes a greater angle (C) with respect to the longitudinal centerline (23) of the needle (10) than does the angle (PI) formed by the intersection of a plane through a flat surface (19) of the tip portion (13) and the longitudinal centerline (23) of the needle (10).</p> |
