Abstract
An externally actuable, hermetically sealed switch is incorporated with an implantable medical device (IMD). A patient applies pressure against the tissue over the IMD and actuates the switch. The actuation of the switch causes the IMD to take predetermined actions, such as recording data, inhibiting therapy, initiating therapy, increasing therapy, requesting information, initiating a communications session, or performing a status check. Thus, the patient is able to interact with the IMD without requiring an external device such as a programmer, patient activator or magnet.
