1. A surgical access device, comprising:
- a housing defining a working channel, the housing having a base with first and second openings formed therethrough;
a first support rotatably disposed in the first opening formed through the base;
a first sealing element disposed in the first support at a location offset from a central rotational axis of the first support, the first sealing element having a first central axis parallel to and offset from the central rotational axis of the first support, and the first sealing element being configured to receive a first surgical instrument inserted therethrough and into the working channel;
a second support rotatably disposed in the second opening formed through the base; and
a second sealing element disposed at a location offset from a central rotational axis of the second support, the second sealing element having a second central axis parallel to and offset from the central rotational axis of the second support, and the second sealing element being configured to receive a second surgical instrument inserted therethrough and into the working channel.

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.

9. A surgical access device, comprising:
a housing having a base rotatably coupled thereto, the base having a plurality of sealing elements including first and second movable sealing elements that are each disposed within a support that is rotatably disposed within a predefined shape formed in the base, the first and second movable sealing elements being eccentric relative to its support, each sealing element configured to form a seal around an instrument inserted therethrough, and each sealing element being rotatable within the base independent of one another, wherein rotation of each of the first and second movable sealing elements relative to the base is effective to move the first and second movable sealing elements laterally within a plane defined by a substantially flat surface of the base to change a distance of the first and second movable sealing elements from a center-point of the base. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
