ABSTRACT:
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. An optional intermediate retractor assembly is positionable between the first and second retractor portions to provide further tissue retraction capabilities.
