Treatment apparatus with electromagnetic energy delivery device and non-volatile memory

An apparatus for treating skin tissue comprising:

• an electromagnetic energy source;
• an electromagnetic energy delivery device coupled to the electromagnetic energy source, the device including an electrode with a tissue contacting portion, the electrode configured to produce a tissue effect on the skin tissue;
• a non-ambient cooling member configured to create a reverse thermal gradient through an outer layer of the skin tissue to an underlying tissue;
• a plurality of sensors coupled to the electrode;
• and
• a control operatively coupled to the sensors and configured to determine whether at least a portion of the tissue contacting portion of the electrode is out of contact with the skin.

A method of producing a tissue effect with an electromagnetic energy delivery device including an electrode with a tissue contacting portion and a plurality of sensors operatively coupled with the tissue contacting portion, the method comprising:

• contacting the skin of a patient with the tissue contacting portion;
• delivering electromagnetic energy through the skin with the electrode;
• and
• using the sensors to detect whether the tissue contacting portion is out of complete contact with the skin of the patient.
