25. A method of preventing reuse of a staple cartridge in a surgical instrument, the method comprising:
-
transmitting a first wireless signal to a transponder disposed within the staple cartridge; receiving a second wireless signal from the transponder to determine one of a first electronic state and a second electronic state of the transponder based on the second wireless signal; enabling actuation of a cutting instrument of the surgical instrument when the first electronic state is determined; and transitioning the transponder from the first electronic state to the second electronic state substantially simultaneously with an actuation of the cutting instrument. - View Dependent Claims (26, 27, 28)

30. A surgical instrument, comprising:
-
an end effector comprising a moveable cutting instrument to cut an object; a motor coupled to the end effector to actuate the cutting instrument, each actuation of the cutting instrument corresponding to a firing operation by the surgical instrument; and a control unit to count a number of firing operations by the surgical instrument and to electronically alter at least one component of the surgical instrument when the number of firing operations is equal to a predetermined number, wherein the altered at least one component prevents firing operations by the surgical instrument in excess of the predetermined number. - View Dependent Claims (31)
