Abstract
Methods and devices are provided for providing surgical access into a body cavity. In one embodiment, a surgical access device is provided that includes a housing having multiple access ports for receiving surgical instruments, and a retractor removably coupled to the housing and having a working channel configured to extend into a body cavity. With the housing and retractor mated together, a portion of the housing through which instruments can be inserted can rotate relative to the retractor. The retractor can be positioned in tissue using an inserter tool configured to seat the retractor and to automatically release the retractor into position within the tissue. The retractor can be removed from the tissue using a cord coupled to the retractor.
