A medical device for treating esophageal atresia may include a woven tubular member having a first end, a second end, and a body portion extending between the first end and the second end. The first end may have a first flange extending radially outwardly from the body portion. The second end may have a second flange extending radially outwardly from the body portion. The woven tubular member may be configured to transition from an initially-deployed state toward an equilibrium state. In the initially-deployed state, the body portion may include an inner region extending from the first flange to a transition region and an outer region extending from the second flange to the transition region. The outer region may surround the inner region. The woven tubular member may be self-biased to be in the equilibrium state.
