A tissue retractor device is provided. The device includes an inflatable tissue retractor head being attached to a distal end of a shaft having a conduit extending from a proximal end of said shaft to the inflatable tissue retractor the inflatable tissue retractor head is optionally covered by a delivery sheath when deflated. The device also includes a handle which is detachably attached to the proximal end of the shaft. The handle includes a port for communicating an inflation fluid through the handle and the conduit to the inflatable tissue retractor when the handle is attached to the proximal end of the shaft. In some embodiments, the retractor device comprises a tensile element slidably attached to the inflatable head, the tensile element configured for controlling and/or maintaining an angulation of the inflatable head with respect to the shaft.
