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 coupled to a retractor. The housing can be have one or more movable sealing ports for receiving surgical instruments. Each movable sealing port can include one or more sealing elements therein for sealing the port and/or forming a seal around a surgical instrument disposed therethrough. Each movable sealing port can be rotatable relative to the housing and each sealing element can be rotatable relative to the housing along a predetermined orbital path.
