1. A surgical device, comprising:
- a distal retractor having a passageway extending therethrough, the distal retractor being configured to be positioned within tissue to provide access through the tissue via the passageway;
a proximal housing coupled to the distal retractor; and
a base coupled to the proximal housing and having first and second holes formed therein that have first and second sealing elements respectively positioned therein, the first and second sealing elements each being configured to form a seal around a surgical instrument inserted therethrough and into the passageway, a center point of the first hole being laterally offset from a center point of the base and from a center point of the second hole, a center point of the first sealing element being laterally offset from the center point of the first hole, the center point of the second hole being laterally offset from the center point of the base, and a center point of the second sealing element being laterally offset from the center point of the second hole;
wherein the first sealing element has a first range of motion in which the first sealing element is rotatable 360°
with the second sealing element in a first orbital path around the center point of the base relative to the proximal housing and the distal retractor, and the first sealing element has a second range of motion in which the first sealing element is rotatable 360°
in a second orbital path around the center point of the first hole relative to the second sealing element, the proximal housing, and the distal retractor.

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.

8. A method of providing access through tissue to a body cavity, comprising:
-
positioning a surgical access device within an opening formed through tissue such that the surgical access device forms a working channel extending through the tissue and into a body cavity, the surgical access device including a base having a surface defining a horizontal plane; inserting a first surgical instrument through a first sealing element in the surgical access device and through the working channel of the surgical access device to position a distal end of the first surgical instrument within the body cavity; and moving the first surgical instrument to cause the first sealing element to move in the horizontal plane along a first orbital path from a first position, in which the first sealing element is located a first distance from a center point of the surgical access device, to a second position, in which the first sealing element is located a second distance from the center point of the surgical access device that is different from the first distance; wherein moving the first surgical instrument causes rotation of the base of the surgical access device. - View Dependent Claims (9, 10, 11)
