The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to medical devices for facilitating the flow of fluids and materials in and/or between adjacent body lumens, for example, a stent which maintains an open flow passage between body lumens. In one example, a stent may have a constrained configuration and an expanded configuration. In the expanded configuration, the stent may have first and second retention members and saddle region extending therebetween. The saddle region may comprise a coil configured to apply a restoring force to tissue surfaces respectively apposed to the first and second retention members.
