until a force is applied by the u shaped part 2 this combination of adequate rigidity of the clip part 1 in its noncrimped configuration and of the ability of the clip part 1 to preselectively begin to crimp at the weakened portions 3a and 4a enables the surgical ligating clip of this invention to ligate a tubular structure in the same manner as a metallic clip that is as shown in fig9 the clip is placed around the blood vessel in fig1 the tips of part 1 touch each other to form a diamond shaped enclosure around the tubular structure and in fig1 the arms 3 and 4 and the members 3b and 4b are approximated referring again to fig1 to 4 the means 6 for holding the part 1 in a contiguous relationship with the distal end of the part 2 can further comprise one or more tabs 7 either the protrusion 6 and or the tabs 7 are movably contained by a mechanical applicator see e g fig9 the means for containing the protrusion 6 and or the tabs 7 at the distal end of the mechanical applicator are known in the prior art and can be e g a notch at the distal end of the applicator after the clip is in an approximated position as shown e g in fig1 the protrusion 6 and or the tabs 7 can separate from the notch e g by a manual force transmitted to the distal end of the applicator the type of mechanical applicator useful in movably containing the ligating clip is not critical to the practice of this invention that is an applicator from the prior art can.
