A device is provided for vibrational stimulation of body tissue in body cavities which are difficult to access, particularly in the nasal cavity. The device includes an expandable stimulation member, which can be introduced via a body opening into a body cavity. In an expanded state of the device, the stimulation member abuts against the body tissue within the body cavity. To accomplish vibrational stimulation, the stimulation member is brought to vibrate at a frequency of 48-70 Hz within the body cavity. A method is also provided for vibrational stimulation of body tissue in a body cavity, particularly in the nasal cavity of a patient.
