1. A tissue treatment apparatus for use in treating a region of tissue located beneath a skin surface with electromagnetic energy, the tissue treatment apparatus comprising:
a delivery device configured to transfer the electromagnetic energy through the skin surface to the region of tissue;
a handpiece coupled in a removable and releasable manner to the delivery device, the handpiece having a longitudinal axis and an electrical/fluid interface coupled to the delivery device; and
a vibration device mechanically coupled with the delivery device, the vibration device comprising a vibration motor, a carriage, and a leaf spring each positioned inside the handpiece, the leaf spring including a plurality of spring arms and a spring body, the vibration motor located in a space framed by the spring arms and the spring body, the carriage attached to the electrical/fluid interface, the leaf spring, and the vibration device, the vibration device having an axis of rotation that is aligned transverse to the longitudinal axis of the handpiece, and the vibration device configured to transfer mechanical vibrations through the skin surface to the region of tissue along an axis that is substantially normal to the skin surface.
