1. A method for sensing within a body lumen of a patient, comprising:
sensing a pH with an implanted medical device coupled to the body lumen or sensing a direction of travel of contents within the body lumen with an impedance sensor of the medical device;
based on the sensed pH or the sensed direction of travel, determining whether the patient has experienced an event;
transmitting data from the implanted medical device to a data acquisition module located outside of a body of the patient; and
releasing the medical device from a wall of the body lumen via deterioration of a bioabsorbable portion of the medical device.
