Abstract
Abstract A device for providing access to a surgical location within a patient is provided. The device includes an elongate body and a sleeve. The elongate body has an outer surface, an inner surface, and a distal portion. The inner surface defines a passage that extends through the elongate body along a longitudinal axis through which surgical instruments can be inserted to the surgical location. The distal portion is capable of having an expanded configuration when inserted within the patient. In the expanded configuration, the cross-sectional area of the passage at a first location is greater than the cross-sectional area of the passage at a second location, wherein the first location is distal to the second location. The sleeve is configured to be moved relative to the elongate body along the longitudinal axis to increase or to decrease the length of the passage along the longitudinal axis.
