The tissue dilation tubes can be preassembled prior to use by utilizing a dilation tube retention assembly which can maintain the dilation tubes in a substantially fixed position and release the tubes therefrom in order to dilate a patient's tissue. Methods of producing the present systems and using the present systems in surgical procedures are also disclosed.
