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