Abstract
Methods and devices are provided for providing surgical access into a body cavity. A surgical access port is provided that has an adjustable longitudinal length, such as by being formed from multiple segments configured to move relative to one another. An anchor can be coupled to a distal end of the surgical access port to help secure the surgical access port within a tissue opening by engaging a distal side of the tissue. Optionally, the anchor can be removably coupled to the distal end of the surgical access port, thereby allowing any one of a plurality of anchors to be selectively coupled thereto.
