A system includes an adjustable gastric band coupled with an injection port. The port includes sensors, a plate beneath a septum, and a vibration generator in communication with the sensors. A first sensor detects palpation through a patient's skin when the injection port is implanted in the patient. The vibration generator provides a vibratory response to detected palpation, thereby providing haptic feedback to a physician who is attempting to locate the injection port by palpating the patient. A second sensor detects a needle striking the plate, and the vibration generator provides a vibratory response to a detected needle strike. The vibration generator thereby provides haptic feedback to a physician to confirm that the needle has been successfully inserted through the septum. A pressure sensor may be used to provide vibratory feedback to the patient to indicate that an adjustment to the band is needed.
