Abstract
A device for providing access to a surgical location within a patient comprises an elongate body having a proximal portion and a distal portion. The elongate body defines a first passage for accessing the surgical location with surgical instruments. The elongate body has a contracted configuration for insertion into the patient and an expanded configuration for providing access to the surgical location. The cross-sectional area of the first passage at a first location of the expanded configuration is greater than the cross-sectional area of the first passage at a second location of the expanded configuration. A second passage is separate from the first passage and is formed integrally with the elongate body. The second passage extends from the proximal portion toward the distal portion and is sized and configured to receive a viewing element for visualizing the surgical location.
