PATIENT INTERFACE DEVICE AND THERAPY DELIVERY SYSTEM

摘要

A method and system for diagnosing a medical condition, alerting a patient that a therapy is impending, and allowing the patient to override or modify the impending therapy are provided. The system may include an implantable medical device ("IMD") and a patient interface device. The IMD may sense a physiological parameter within a patient, determine whether the physiological parameter qualifies for therapy based on a therapy criteria, and alert the patient via the patient interface device that therapy is impending if the physiological parameter qualifies for therapy. The patient may be given an opportunity to respond to the alert with the patient interface device and send an therapy modification indication if the therapy is not needed or wanted. The IMD may wait a predetermined period of time for the patient response and deliver the therapy if the patient response is not transmitted before expiration of the predetermined period of time or withhold the therapy if the patient overrides the delivery of the therapy within the predetermined period of time. The IMD may adjust one or more operational settings applied during its operation in response to the activity of the system. The patient interface device may be configured to avoid accidental override or modification of the delivery of the therapy.
