Methods and devices retract tissue for minimally invasive surgery in a patient. A retractor includes a working channel formed by a first portion and a second portion. The first and second portions are movable relative to one another from a first configuration for insertion that minimizes trauma to skin and tissue to an enlarged configuration after insertion to further retract skin and tissue in a minimally invasive manner. Instruments are engageable to the first and second portions and operable to move the first and second portions relative to one another.
