ACCESSING DATA STORED IN A MEMORY OF A SURGICAL INSTRUMENT
A process and system are disclosed for downloading sensor data, stored in a memory device of a surgical cutting and fastening instrument, to an external or remote computer device. The process may involve storing data from one or more sensors of a surgical cutting and fastening instrument in a memory device of a control unit of the surgical cutting and fastening instrument during a surgical procedure involving the surgical cutting and fastening instrument. Next, after the surgical procedure, a data link between the control unit and the remote computer device is established. Then, the sensor data can be downloaded from the control unit to the remote computer device.
