Claim 12:
13. A method for forming superelastic Nitinol arms for a clipping device for treating tissue, comprising:
inserting a first Nitinol stock in a first recess of a female portion of a die assembly, the first recess sized and shaped to have a desired geometry of each of the arms for the clipping device;
inserting a second Nitinol stock in a second recess of the female portion of the die assembly, the second recess sized and shaped to have the desired geometry of each of the arms for the clipping device;
mating a male portion of the die assembly to the female portion, the male portion including a first geometrically complementary protrusion sized and shaped to be received within the first recess of the female portion to configure the first Nitinol stock to have the desired geometry of each of the arms and a second geometrically complementary protrusion sized and shaped to be received within the second recess of the female portion to configure the second Nitinol stock to have the desired geometry of each of the arms;
placing the mated male and female portions of the die assembly in a fluidic bath having a temperature of approximately 500° to treat the first and second Nitinol stock having the desired geometry; and
removing the die assembly from the fluidic bath and water quenching the die assembly to set the first and second Nitinol stock in the desired geometry.
