Abstract
A surgical access device can include a plurality of retractor members that together define a lumen having a first cross-sectional dimension. Each of the plurality of retractor members can be moved radially outward to at least a second cross-sectional dimension to create a surgical access passage. The surgical access device, systems and kits comprising the surgical access device, and methods of using the surgical access device can include a mechanism for inserting an elongate member from exterior the body to the surgical site, a mechanism for moving the retractor members radially outward, a mechanism for guiding the radially outward movement of the retractor members, a mechanism for securing each of the retractor members in a range of positions, and a mechanism for illuminating the surgical site. Variations of the devices, systems, kits, and methods are useful for creating and maintaining a surgical access passage for performing minimally invasive surgery.
